- Enter the intricate world of surface mount components and learn to solder on a smaller scale. Once equipped with the right tools and a bit of patience, you'll be soldering minuscule parts like a machine.

No no no, don't solder like this! Use flux and don't go over all the solders with that solder wick it will damage the pads, pcb and the risk of shorts are really high.
The thumbnail for this video is a work of art.
Use some liquid flux first.
some flux and less solder will be better than your way
I was told by a hand pocket watch maker, "never drink caffeine when dealing with small parts." It allows you to be more precise in your body movements.
If you're bad at something, don't try to teach others...to be bad at something.
I didn't realise how good this guy really is until I tried SMD soldering for myself
More Colins lab please. This man inspired me to give hobby electronics a try.
He talks and looks like an "agent" from The Matrix.
"You too, can work, like a machine... Mr. Anderson"
FLUX Dude!
I agree on this video about 'anchoring the first pin' - but drowning the pins with solder and suck it off afterwards is not really how I handle these SMD / TSSOP devices;
Watch out for the QFP chips with a central bottom pad. While some of those center pads are just for thermal dissipation others actually are important ground connections. On those that have important grounding requirements, your technique will not provide reliable results. On those where the central pad is only for thermal reasons, you may have to watch out for heat dissipation. Getting that bottom center pad actually soldered is nearly impossible using only a soldering iron. But one technique that could work is instead of soldering the single corner pin, use a low temperature solder and lightly tin the bottom pad on the PCB and the pad on the chip. A very thin coating. Then heat the PCB from the under side to re-melt the solder and make that the first connection to a QFP, not the corner pin. If you can get your hand on a small tube of solder bearing paste, then use a small drop of paste on the PCB pad instead of tinning the PCB pad and the chip. Still very difficult to make that solder connection with a soldering iron. if the PCB has thermal vias the transfer heat quickly through the PCB to the pad, that will make it easier. But the whole process will be quite a bit easier to do with a hot air gun. With a hot aid gun you can also do BGA chips. If you're doing a lot of QFP chips, buy a hot air gun and a small tube of solder bearing paste. You'll eliminate a lot of problems. Keep the solder paste in the fridge so it doesn't go bad (it will separate if you don't) and use it for those special chips.
I use painter's tape cut into thin strips to hold down large multipin devices before soldering. This lets you reposition and align the device before applying any solder at all.
Super useful, always been terrified of surface mount despite cost advantages, but this video has inspired me to have a go. Thank you!
Hi Collin! Love your tutorials! One question, I noticed that you used the Hakko soldering station for this (SMS) project. What temperature did you set your Hakko to? What soldering tip did you use? Thanks much!!
Wow! Thank you for this video! I'm blown away... I wish I saw this video before I started connecting my neopixels!
Is there any specific breadboard to prototype your project with SMD?
You're the only reason I'm subscribed to this channel.
this de-soldering pump is really nice looking, i ended up buying one.
