@jdslyman Lol, I still do that. Thought it was just to scrub dirt off the contacts
EDIT: I thought you meant just reseating, not dropping the whole thing
I believe a more important question would be why electronics die the day after warranty expires :/
Jonathan De Felice that is the day for the micro trolls to mate with your components fucking up your computer.
right, my iphone die exactly 1 year after i bough it, no waranty because of litle scratch on the body, right
GreenDisplayGaming I was just joking. usually, appliances die the day after the warranty expires lol who knows why..

I have a tape recorder from 1958 that still works perfectly - with it's original capacitors....

I was about to brag about my VIC-20 working for 40 years on the original capacitors, but I think your tape recorder has my VIC beat by a few years.
Bruh. That's Just One Year After My Country Independence.
@MrNeutron98 careful to not cut yourself on that edge
Honestly capacitors in a tape recorder probably get charged and discharged less often...

Planned Obsolescence is absolutely a thing.
The HP 4000 and 6000 series printers both have small, cheap sponges near moving parts that are reportedly for noise reduction. The trouble is, they're held on with some pretty good double sided tape. Over time, the sponges wear away and parts start to stick on the now exposed tape, causing paper jams. The fix is to just scrape it all off and wipe away the sticky residue. Funnily enough, I've never been able to hear the difference in a printer before or after those "noise reduction features" were removed.
If it was just the 4000s I might buy that it's an honest mistake but when the same exact flaw is in the newer 6000 printers, in the same exact spot, I call shenanigans.
HP has always been like that though. just look at the old deskjets, if you're lucky you'd be able to actually finish an ink cartridge before the printer itself fails...
also in the early to mid 2000's their computers, their computers where designed as so you would throw it in the bin and buy another as soon as, if not before the warranty period runs out. my aunt got a brand new 1.8ghz Pentium 4 from them shortly after i'd built my 1.4ghz Pentium 3 and tried to tell me that her's was better than mine... the netburst p4 was slower than my p3 for a start (not HP's fault) however, whilst i was struggling with a pitiful 368mb of ram, HP figured that not only was 128 megs plenty for XP and all their factory installed bloat, but they felt the need to sacrifice 32 meg of it on a pitiful onboard gpu! heck, my videocard had access to more memory than her windows did... not bad for the $1,000 price disparity right?
I will NEVER use an HP printer, Epson and Lexmark are way more reliable
ThunderClawShocktrix I use a mid nineties HP Laserjet 4 plus with a million and a half pages run through it. It's built like a tank and still produces prints like new. The only things I have replaced on it was a
fuser once, a couple of pickup rollers and toner cartridges.
Planned Obsolescence is super common among appliances.
So we can call for sure HP is the worst tech company for both PC/Laptops and Printers rolf!.
My PS1 and N64 still running fine after over 19 years
well systems from 20 years ago are different than todays standards
I would call it because the hardware in n64 is big af that means it lasts longer
Money wasn't a thing that time, more for happy customers. Now short lifespan so we have to buy again. Tbat time was also when everything was discovered. So game companies pc companies exc- want to get more and more and take the most out of the devices. Now we have dlc's buy in a store. Not only that. In 2000 exc- they never heard of that. Now we can buy lvls. And like the last finalfantasy unfinished game. Game updates exc- or look at windows 10. Thwywant full control now. Times have changed badly. All for the money not for the customers. Fossil phones where better and when you dig one up sure you still be able call with it. It's thisdays business tricks.
@@dennyd2724 well said.
You should worry about perserving then
how about the reset button on your PS1?
This is fascinating. As a lover of vintage technology I've been learning about various ways to repair those tiny physical defects, and there are ways to fix most anything short of electron shenanigans. So from what I've seen, the way a vast majority of electronics die before their full lifetime is because they are no longer in the possession of somebody who cares enough to do the often simple maintenance and repairs that can revive them. Of course once there are no longer any replacement parts for vital components that are truly beyond repair and cannot be produced by hobbyists and enthusiasts (mainly the heavily guarded industrial secrets) life as we know it will be turned upside down, but I don't see that happening for a very long time.

Planned obsolescence should be illegal at least in most cases
It is illegal in some cases, plane stuff and baby stuff for example.
It doesn't matter. The corporate big-wigs get their work-arounds via toxic updates and "instabilities" and "patches"... You ever wonder how (for instance) a company like Microsoft can hire a literal army of software engineers, all working toward the same general purpose, and still not accomplish a single completely functional operating system by the date of release? Think about that... And note, I purposefully used "date of release" not "deadline" or "due date"...
As to "the same general purpose" (since someone will doubtless complain for ambiguity)... It's simple. As part of a single company, the individual will want to keep working (even gain rank within the company) so it would stand to reason, sending a reliable, useful, durable product to the public for all its accolades would gain the company respect, loyalties, and return business...
Instead. within a day of being released, there's a patch and a stack of updates to keep your computer humming till (what seems like) rapture. So... not even a day of operation? Not a couple hours test-drive on the information highway? No, more updates... more patches... more "sorry, but this shit don't work right either, so you'll be able to have use of your computer in a few more days... weeks... oh hell, just forget about it and smoke weed like a good little soldier... :o)
As much as I am sure that planned obsolescence is real, I also believe that many times it isn't a conscious decision by the manufacturer and is actually a natural part of statistics and market pricing.
That's true and it would be difficult in a lot of cases to prove intention.
I had a USB wifi adapter fail, within a day, exactly a month after I started using it. It's not like I can sue the Chinese company responsible.

Planned obsolescence is a very real thing. I used to work for a company who were masters of this. We would be in the prototype phase and when we designed a part, it was in the framework of "make it last, but not too long". The price of a part would be equal if we used the heavier gauge steel instead of the lighter, but that would make it too robust, too long of a lifespan. So we choose the thinner stuff. And we plan it to fail two to four months from warranty expiration. And to make it worse, we could make the failure to appear the user's fault. That is what I had issue with, and thus ended my employment there. No place for that sentimental dawdle in this day and age.
why use one's family name as the company name?...
That is why no modern car will see classic stage!
"Planned obsolescence" is not a thing or, more precisely, it's usually misunderstood, it's not a plot to exploit people by somehow knowing exactly when something will break or wear out. All it basically is is the intersection of cost and demand i.e. "how much are people willing to pay" that determines the quality or lifespan of a product. For example, how much would you be willing to pay for a typewriter that lasts a 1000 years? Probably not ever much since typewriters are obsolete technology.
We can build things to last longer, yes, but most customers are not willing to pay very much for a smart phone that lasts 20 years when it's obsolete in less than 5.
It's customers that drive "planed obsolescence".

I have worked in NAND drive development for 8 years. If all goes well we know the precise number of cycles we can read write or clear bits. Done properly, we can slowly and safely manage the data. Using trend analysis we can even alert you ahead of time before a failure. As NAND gets smaller it wears out sooner. This is why old devices from the 80's will actually outlasts newer devices.

Here is how: czcams.com/video/Jwk79w_-13H/video.html
Nice overview. Three key points to add:
1. Important to stress the most common causes of failure and how users can avoid them (e.g. heat, abuse of connectors, dropping, liquids).
2. Biggest problem I've found is that websites become bloated with videos, pop-ups, scripts, etc. so that more powerful hardware is required to deal with them (alternately, ad blockers).
3. Some of the long-term problems you mention could be planned for by ensuring that vulnerable parts can be replaced. Batteries, hard drives and memory for example.
It fascinats me how electricity behaves very much like water. The effects he's referring to become far more noticeable when you deal with high energy electronics that operate in the megawatt range. A lot of parts in these type of devices have to be replaced due to wear caused by the huge amounts of current going through them. The damage resembles sort of the wear and tear of water on on pipes and river banks overtime.
He doesn't mention a VERY important reason why capacitors fail; because manufacturers are cheapskates who under-rate their components to save a few cents. Lower voltage devices are cheaper, but putting a 6 volt capacitor in a 5 volt circuit is suicide for a circuit board.
So put a 2 volt capacitor wrong connected in there and everything will work fine again
that wasn't due to de-rating though but bad production methods, the electrolyte was contaminated.
Just wrong though. A 6 volt capacitor can STAND 6 volt, and actually is "over-planned" by 1 volt and works just fine in a 5 volt circuit. It's more like they put max (!) a 5 volt capacitor in a 5 volt circuit or maybe go even slightly lower, planning for no headroom (though turning on certain devices draws MORE volt than usually is there for a short periods of time), therefore the lifespan is shorter. Headroom would just cost more money, so they try to avoid it. But you were close lol :p
Smoke 165
@@smoke1659 I think he meant that the board would die by being fried by a 6volt over the 5volt.
I have a 1915 Candlestick telephone what still works on a current British Telecom connection. Although, the oldest electronic I use often what still works would be my 1934 Elextrolux Z25 Vacuum Cleaner complete with box and attachments. I Just can't see my modern Dyson ball working until the year 2100 though in 83 years time.
I also prefer the brushed ali build quality of older 1960s/70s hifi equipment too. You struggle to get that these days its made in either plastic or black and rather bland looking instead.
Dyson obsoletes all his models, as soon as he releases a new model, he stops making parts for the old one, and when it breaks you can't fix it.
Older style (or metal commercial) vacuums in genral much better than dyson.

This was very educational! I'm an EE/inventor. I have a flying invention on my channel with no moving parts except ions and electrons. I was trying to figure out reasons why it isn't too reliable yet, other than the obvious. Perhaps, if I add more lightweight cooling fins it will at least prolong the life of the affected parts. I never hear much about electromigration before either.

That military class motherboard actually died on me about 6 months ago...
How old was it ?
He grilled cheeseburgers and fries on it. just kidding.
the military class is absolute bullshit compared to actual military class motherboard which is water stress and drop resistant. maybe like titanium cpu pins on motherboard and waterproof coating maybe would kinda make it "military class"
Just a marketing wank. There's no official objective standards it needs to meet to be qualified as "military grade", they could probably cite some paper pusher using a cheap pre-built in an ROTC staff room as validation of it's military grade quality.
What does "military grade" even stands for? Do soldiers bring those along to play some Club Penguin (oh...) in between raids? There's no official tests or standards to it, neither an independent org to test them, it's just something people eat up thinking it's actually better - "oh, why I paid a hell lot more for this mb that offer pretty much the same of much cheaper alternated? This one's a military grade mb, bro!"

(Aug 2023) - I just caught this amazing video. Marketing always talks about how great the products are. Service and repair videos are very few and far between. One thing that wasn’t mentioned is variation in manufacturing. I think manufacturing engineers, and the people who actually make things so well every single day are the unsung heroes of the electronics industry. Put it another way… If the connectors to a power supply are not crimped correctly, that connector will eventually fail.
Thank you again for a great video!
If you think of how much electronics are found in cars today and how many things they control(engine management, safety features, keyless entry, stop/start, traction control emergency breaking, lane assist, adaptive cruise control ) plus the temperature changes they operate at compared to pc's it is more than a bit scary to think what would a failure or malfunction could do.
That is why I drive a 20 year old carburetor car. Only ignition and sound system is electronic.
my father had the FICM..."Fuel injection control module" go out in his 2004 Chevy Duramax truck. The truck has only 160K miles on it and is in great shape. GM or Isuzu (manufacturer of the engine) doesn't make them anymore. No aftermarket manufacturers make the FICM, nor can a modern part be adapted. The only ones out there are from scrapped trucks. He had to wait 4 months to get one from a junkyard.
Planned obsolescence is a scumbag move, but even more on mobile devices. In PC you can get away with an i5 2500 at this very moment, on phones the next android version is most likely not working for your model, no idea how it works for IOs though.
Apple's updates for the iPhone are pretty good and they support devices going a few years back. The new update that launched yesterday is available for the iPhone 5, which was released in September 2012. I have a iPhone 5s (2013) and it's still working fine. The only really noticeable speed decrease is when I'm loading the facebook/messenger app where it takes up to 10 seconds for some reason. The biggest problem is that the 16GB memory (more than enough in 2013) is too small right now and there is no way to upgrade it other than buying the 32/64 GB back in 2013.
get away with an i5 2500, my dad was using a Pentuim D (two pentuim 4s) as a daily driver for a while at work. My nan still uses a C2D machine, and i had a gaming machine using a Q6600, nothing is wrong with the LGA775 CPUs and they still work lovely.
the A7 is still a powerful chip, it outperforms most of the budget sector today.
on android each upgrade makes the device better, if you can install the newer version. I'm using a Sony Xperia M with 4.3, and is quick as was with 4.1 (maybe a little bit quicker but eh)
fuck you talking about. im still using a samsung note edge from 2012 and its doing just fine. running latest version of android no problem.

Planned obsolescence sometimes backfires, my washing machine went splat a month before the warranty was up.

now explain why my IBM 8088 built in 1988 still work perfectly but a pc i bought in 2005 is basically a paper weight i scrap for parts and uh screws cant get enough screws
If electrical engineers wanted to, they could make things last like for ever. But there's the thing with earning money...
Different devices have different life spans. It is not that old technology lasts better. New devices just cannot have lasted long and we see only those examples of old technology that have lasted.
If they were made to last long they would cost too much.
Planned obsolescence
The computer from 1988 was $1500+, the computer from 2005 is 50x faster but cost
I have always had issues with surface mounted components in that not enough solder typically makes the connections to them leading to breaking intermittent connectivity over time through heat and cold stresses having that lead to ultimate failures within the circuitry. Indeed, planned obsolescence due to lack of enough solder on the connections. Through time, they break apart and no longer are dependable. What's worse is that in the wave soldering process it IS possible to bring forth enough solder to make that not be at issue, but most manufacturers don't and/or refuse to make it any sort of a priority.
cheap manufactering
A lot of it is ROHS requiring solder be lead free (In order to be imported from china). Leaded soldering so much more effective. Other solder chemicals like silver can be used but it's too expensive to be used on a wide scale.
Don't often click on the random vids YT recommends but when I saw a much younger looking Luke I got curious. An interesting fact relating to thermal expansion: The first electronic* computer, the Colossus I, was built during WWII to help decrypt Nazi Tunny Codes used by their naval forces (their army used Enigma codes which were defeated with an electromechancial computer called La Bomba). When the proposition to build Colossus was first made there was a lot of push back because it was a well known fact that vacuum tubes (which the British call thermionic valves) failed quite rapidly, fortunately there was someone there (I think Tommy Flowers) that had experience with vacuum tubes and knew that so long as they kept the tubes warm they would last a lot longer. The reason the tubes normally failed is because of rapid heating and cooling.
*Colossus I and it's successors were special purpose computers, the first general purpose computer was made later using similar principles.
Short, clear, precise knowledge without periods of fabulation .
My Commodore 64 still works fine. I purchased that in the 80’s.
Markinpuff what??! I use to love centipede!😊
Zelda Williams Come and take it. Lol
Both my c64's work perfectly, as do 3 of my 1541 drives. I have had to swap a few chips on my '85 c64. My silver label '82 c64 is perfect, and that has mostly original '82 chips.
I got the impression from the video that new and smaller architecture CPUs would die faster because the transistors are so small. So maybe older machines will last much much longer due to the larger architecture of the CPU.
also if you never use it that will probably help prolong its lifespan.
So that makes me wonder if I buy the newest and most expensive CPU available today, will it be dead in 5 years, whereas a CPU from 20 years ago would probably last many many times longer?

sri krishna you probably ment electrons
no atoms
not just electrons as metalloid or e precise elements like Se and Ga are actually what you called as processing units so yes he meant to be atoms and really atoms including protons electrons bosons quarks matter waves and all these stuff
Yes and no... I mean, technically it is the electrons that are the electricity. So, no it isn't atoms but is particularly the electrons that are doing the most to help you play. However, yes since the electrons are part of atoms and wouldn't be useful without the protons and neutrons. But then, you literally are doing everything in your life with atoms because all matter (including your body) is made up of atoms. So, everything you do in life involves at least the atoms that make up your body, the ground you walk on and the air you breath... and more if you sit down, touch something or in any way interact with anything. There is just no escaping the involvement of atoms in life.
photons, it's just manipulation of photons, but then again life is filled with crazy shit so idk, maybe another universe
literally everything is atoms

Props for mentioning electromigration and hot carrier injection. First time I think I've ever heard either mentioned outside of the industry (even if the latter not by name).
There's also another phenomenon related to HCI: negative bias temperature instability. Similar results, different cause, but it's reversible. NBTI is a big problem for modern devices, but ICs have circuitry built into them to counter it.

And it has to leave the VPN endpoint, because somehow, you requests need to reach the actual target. So, VPN isn't the single holy grail for secure communication.

Of course, many people and even *tor* recommends to not only relay on its jumping points as a leak can make them trace you but aside from that, today i had exactly a very scary conflict , by using a new phone with all knew unconnetced to my other account gmail, somehow i got recommends based on serach from my family despite iam being on totally different wifi and never ever connected to my family wifi, all am thinking of is that they personalised me with my sim card number as it is the only think common, when ive got a recommendation for an old game of 10+ years played by my brother i knew they connected some dots together, to be Honest , i felt really sad and privacyless ( if that is a term) its really an invading to what you do by those Google servers, sad to see things went this far.
I want to explain that and reach out and shout between provacy and computer/net freedom community to make this a global announce, yet am thinking even if we impacted all that google might still have hidden shadow of what you do since they have the technology.
A most useful and informative video. Thanks 😊
Because Linus drops them
Because they need you to buy more of their products

Thank you! very informative. I've always wondered about that. PS What is the most robust information storage medium for archiving data, we have today? Lastly, do think it's reasonable to overclock a PC, given that it will obsolesce before it gives out? On that note, if a system is overclocked and cooled properly, will its lifespan be diminished as a consequence?
Coorperate Overlords😂 with that apple shaped face
That gave me LoLs
Thanks! I realize you are speaking of plug in devices. Here are some additional observations with installed systems based on over three decades in the business. Alarm systems rarely cycle power and some fire alarms are 30+ years old. Many are highly stable. The biggest problem is high voltage power spikes such as lightening. I have seen plenty and learned a great deal. However, much of this is mitigated with newer power supplies and selecting industrial grade surge protection. People may help save devices by unplugging them during a bad lightning storm. An iPad obviously does not need 120 volts during that time. We have UPS power supplies on all desktops, stereo, TV’s, Tivo’s; Siemans surge protection on the Main electrical panel and on both central air condensers’, and because we are on a ridge, we have lightning rods on the roof with a bonded ground system. We even use cascading Lurton Maestro dimmers on all down lights and only had two lights burn out in 23 years. Be a victim or be a wise guy.
Shame you skipped one of the more common failure causes, especially in modern computers: timing mismatch induced short circuiting. When you build massive networks of logic gates to form all of the necessary logic to make a computer of any sort. You have a minimum time you must wait before you can trust the output of any logical inversion, the time it takes for the signal to go from the input side to the output side. When you break the essential circuits down to logical inversion in diagram form, it's pretty clear there are some paths faster than others. Imagine this: you have a wire that can have voltages in it ranging from 0.85V to 1.35V. Some things connected to this wire can't handle the full 1.35V while other's can. It's just not feasible or even possible to separate them due to what they are needed for. So you build a gate system that will shut off that power wire to anything that might be hurt by the full 1.35V if it's about to be changed to that voltage. Simple solution, works really good majority of the time. However we want blazing fast chips so we do this as fast as possible with no wiggle room for maybe an electron going missing from that "shut off low voltage circuits" line.
Chips suffer from this a lot, they are built for it with a stated tolerance level based around exactly that problem. The higher end of the tolerance is where it's going to happen enough to notice a difference in lifespan of the chip. This is also where the mistakenly though up "Planned Obsolescence", at least as rampantly, actually comes from. They know in a few years, your most likely going to upgrade your machine or just replace the part at significantly lower price from age depreciation. So why not pick how hard your pushing things to provide the best bang for the buck for the range of time your expected to own it. It's a tradeoff of lifespan for balls to the wall power.
Alan Hunter this doesn't explain why electronics fail over time. If a designer designs around this 'hold time', then we expect not to have this occur. So does this 'hold time' change over time?

downvote. voltage moves at 10% the speed of light, this is a fucking non-issue even if the circuit was a meter longer.
You think I am gonna read that?
The apple reference was spot on!
👍
Great Posting, glad I watched it!

I love his SMOOTH transition from manufacturers purposely designing products for failure to his VPN sponsor ...
Electrostatic Discharge (ESD) kill electronics. Why is that not covered?
He also missed RoHS solder issues such as tin whisker and cracking of BGA joints.
Do good electronics get go to heaven?
Trev6511 depends on what the user did with them. ( ͡° ͜ʖ ͡°)

My Ps2, is in a better place now.
Over three decades of managing hardware, the main and most prevalent culprits are heat cycling (don’t turn off after running hot), vibration, bad power line conditions, software updates degrade perf and even can cause physical damage.
I did not think any body can cause anxiety and stress in just the first, 0:05 seconds . You succeed dude . Good video BTW
Wow I really didnt expect to hear of electromigration in such a video. Impressive! And it was quite good explained as well :-)
What are Electrolytes? Its what they put in Brawndo.... But why do they put it in Brawndo... Because it has what plants crave. YEAH.. cus It has electrolytes.
Best reference. Ever.
I found this very interesting. Thank you.
Thanks a lot for good information sir.
Harambe is never forgotten!
Mechanical and hydraulic systems usually give a fair bit of warning before they fail completely, but when electronics fail, it's usually without any warning. This is what concerns me about modern vehicles, as "drive by wire" systems are becoming more and more common. Electronics tend to be one of the less reliable aspects of a car.
I once had a Toshiba Satellite M105. It helped me through quite a bit for 6yrs. Rip laptop you've left quite a trail of frustration for me and possibly your previous owners. But may your circuits help those in robot hell.
So my guess was right, about the damages in the soldering spots. I didn't know that for sure, now I do. Thanks!
I dont think dell does planned obsolescence. Yeah i know the dimension machines and a couple of old system broke from design flaws, but a dell optiplex from 2006 can still be used to day and same with i laptop i own. If a system meets the minumum required specs, i could run a more modern os
CalculatinGenius just took apart both of ‘my dell optiplex and used one to upgrade the other now it works fine
Remember Dell doesn't necessarily make the parts for three PC. They come from different places like how your professor comes from Intel.
Javian, pretty sure Intel doesn't make professors lol.
HA. HA. HA. HA. Tell that to my sister and father, who have had 2 and 1 Dell laptops die on them suddenly, respectively.
@@bennemann Sigh. Basic maintenance. Like changing thermal paste and cleaning the dust every 1-2 years. Swapping the drive after a few years. Done. Finito. Spanky new working PC.
the atomic scale is much smaller than the "microscopic" scale, wtf
Shshhsh :D
The old axiom about "moving parts = failure" crumbles when you consider how many more failure points there are in an electronic substitute for a mechanical part.
Perfect example is the $350 Anti-Lock Braking control module for my car. It is no longer communicating with the Engine Control Module (main computer), so it has likely had an internal physical failure. The mechanical aspects of the braking system work just fine, however - the car slows and stops just as it ever did when pressing the brake (it has simply reverted to a non-ABS system). Both the mechanical components and the electronic ABS control module are the same age, but I'm about to burn $350 and an afternoon to make a light on my dashboard turn off, due to an electronic failure.
Plastic parts (a.k.a. PEMs, or plastic encapsulated microcircuits) also absorb moisture, which eventually leads to internal corrosion. Contrary to popular belief, plastic is not a perfect sealant. If you need a hermetically sealed part, that requires a ceramic package with a sealed lid.
During manufacturing, there are baking procedures to drive out any moisture PEMs absorb prior to soldering. If they aren't preheated and dried out, they will pop and crack when they are soldered. Just one more thing to think about.
4:40 so accurate lol
Rip over clocking
i almost burnt out my 1000$ gpu with over clock every thing started crashing and i was like oh $#*%
thats cause you dont know how to overclock and whet to high on the core... 2110mhz on a 1080ti... free frames in games yah know
This makes me realize how difficult interstellar travel will be. Even if a ship has multiple genetations of people, the onboard systems will gradually fail.
Sometimes my remote that I use on my tv stops working , and installing fresh batteries doesn't fix the problem . But I have discovered that by taking out the batteries and leaving it alone for maybe an hour , when I put the batts back in , it seems to work fine again ! What happened ? Was maybe a capacitor acquiring charge and retaining it , but taking out the power source and not using the remote for a while allowing that charge to leak off ?
It's very informative for us to understand how Electronics fail over time due to using. 😎 😎 *Nothing last forever* is the truth.
WHO SAID HARAMBE DIED???
kelvin kam me
Everyone.
Harambe really is dead. A child fell into his cage and Harambe decided to play with him. The zookeepers thought that he tried to kill the child, so that led to him being shot.
