    Your laid back approach is AWESOME. Your not stressed and simple direct explanation is just what newbies need. Your system is exactly how I make my boards and mine come out excellent every time. I skimp and use ferric chloride hexahydrate and caustic soda but I have been doing it for years and know the measurements. Also an etch tank with a fish tank bubbler and heater bring the etch time to under 8 minutes depending on copper thickness. Dry Film Solder mask is cheap and easy with a laminator.

    Thanks for the kind words. I have finally perfected the process all the way to solder mask. It comes form a conglomerate of others work and tweaking it. In a nutshell, there are papers out there saturated with silicone oil that toner prints to with no problem (assuming the write paper) and little pressure initially with the board hot and flat and clean. It transfers perfectly then once stuck in the right place, in my heat laminator2X. Cooled and done right it peals right off and reuse the sheet.

    I have been making pcb s for years. I made a rocker for the solutions, uv light box and using a Dremel drill on a flex cable.
    There are now new products and procedures that are really fascinating, I use a MacDraft Pro drawing program to create the positive circuit and print it out on an old hp 5000 printer to the transparency sheet. I like the idea of using two stacked prints to enhance the pattern. I sometimes use a heat lamp (150W lamp) over the etchant to warm it up. I made a vent hood with squirrel cage fan to blow fumes out. I am still experimenting with the photo resist sheets, (now on order) and using the hard to find photo resist in the spray can to try on my home made pcb spinner, that will be used in the hood. Sorry I went on here, but that about covers it. //... Joe

      This is a homemade circuit board manufacturing process.. a board such as that's inside your own computer or PlayStation.
      After having done making the board, one can 'solder' electronic components on it. You can make your own radio station or a satellite receiver or whatever you want.

    Making my own PCB's was fun the first couple of times. It was much more fun when that mail arrived with a top notch, superbly manufactured rendition of my design. I still had all the fun of designing the circuit, and laying out the PCB. A factory with the right equipment did a top-notch job realizing it, for a cost that I could never achieve making a lower quality version myself. Many DIY-ers naively calculate cost by assuming their time is worth nothing, and gloss over quality differences.

      I followed this video, but instead of using a CFL bulb I used a halogen. I put the board after it in the developer, but it came out exactly as it was, like nothing happened. My board was sold as photosensitive, it came with the protective sticker, but never looked green or blue. Just copper color. Do you think only the lamp was the problem? After putting it into the developer I killed the photosensitive layer, right? So I cannot repeat it with a CFL and the same board? If I cannot: can I still use the board with marker / iron method? Thanks a lot in advance!

    I've found that a laser engraver is fantastic for making custom pcb. Rather than having to rely on those light sensitive boards, simply paint the whole board black, print your circuit out with the laser engraver removing the unwanted paint i.e. the copper that is to be removed. Then continue with Ferric Chloride.

  • @robertrandom3450

    In my opinion, harmful etchants (like ferric choride) are un-nessisary to develop board. They require special disposal, are environmentally un-cool, and require special safety measures. I use white vinegar, salt, and hydrogen peroxide to etch boards. Results are always perfect. These chemicals are far more benign than methods suggested above.

    An excellent tutorial. One suggestion: the very thin drill bits that I use -- 0.04" -- can easily "dance" away from the hole that are intended to be drilled, particularly on this very hard phenolic board. To limit this, I use a center punch in order to create a very shallow divot on the hole as a wide to guide the drill bit during early moments of drilling.

  • @jtsiomb
    @jtsiomb Před 8 lety +30

    Ferric chloride is horrible, and 20 minutes wait time is a joke. I prefer a mix of hydrochloric acid and hydrogen peroxide. If it isn't smoking, add more hydrogen peroxide to taste. Etching is done in 2-3 minutes if you stir a bit, and the leftover HCl and cupric chloride in the container can be reused a number of times, by adding some more hydrogen peroxide when it seems to lose its potency.

      +John Tsiombikas You're right. I had been etching PCB's for a longtime with sodium persulfate and it took almost 30 mins. That stuff is also pretty expensive, it had been a longtime since I done an electronic project. I will start with this hobby again soon but with better equipment. Better solderstation, using silkscreening to create professional PCB's. I'll also make a DIY etching tank with plexiglass. It's very cheap to make one yourself instead of buying one.

      Why is a twenty minute wait time a "joke"? I'm just considering that the board(s) could be used for years, so spending twenty to thirty minutes during this step of the manufacturing seems a reasonable investment - especially when compared to the many days or weeks it cane take for a third party manufacturer to produce the board(s) for you.
      I also feel that the satisfaction for creating your own circuit board(s) should out-weigh the whole process. If, however, you wish to mass produce your board(s), then certainly try other processes in order to reduce manufacturing times.
      I feel the bigger picture here is that anyone can create their own circuit boards, and even their own circuit components, at a low cost. What does it really matter if we need to wait minutes or hours to do so? The process of creating your own components, and thus the feeling of accomplishment, should - in my view - balance the effort required.

    What I always use is regular A4 paper instead of transparent sheets. It'll block more light but, the print is very sharp and does not have holes. So no need to print it twice. You need a laser printer for that though.
    4.5 minutes in UV light and you're done.
    You can also use a marker to draw your layout on the board. The marker paint will protect it while you are etching off the copper.

    Nice tutorial on PCB etching! I use almost the same method except the photoresist type - I use "POSITIV" spray. Covering patterns with some oily liquid (e. g., glycerine) is another way to stick them together and to the board so no any frame or glass piece is needed. Also, 'drill-aid.ulp' Eagle script (included in distribution) is very handy when you use manual drilling. The script reduces hole diameters to a selected (small) value more suitable for drill centering.

    my etching method is sculpting on PCB covered w/ musking tape w/ a cutter to engrave the layout,oldy as it is but still works fine

    Thanks for this tutorial! This method is very professional and very expensive, also you can't store photoresist board or foil for long (6 months-1y and sensitivity decays). For amateur work I prefer direct transfer of toner by heat, with some retouch.

    very impressive and looks easy the quality looks just like a one ready made

    Great job on this process. I did this in High School Electronics forever ago, only we used fingernail polish for resist, with no photosensitive coating. Real caveman, but it works. Again, Excellent video.

    I use a special paper that has a rating of 100 pound. Just iron the toner onto the board and soak in warm water for 10 min and you have a board that is very close to factory level. This is a great video too.

    I have the photographic negative for making the pcb , but Im not sure how to start making the PCB yet, thanks for your video it was the best I have seen so far.

    Collin, I recommend etching with Water + Muratic acid + Peroxide. It takes 20 seconds or so, compared to the 20 minutes of Ferrochloride. Just make sure you do it in a very well ventilated area, with a respiratory mask.

    Tip: use tracing paper instead of transparants. Toner adheres much better and because of the fine grain, layouts can be very detailed. It's cheaper as well. UV exposure needs to be a little longer.
    I don't need to double-up the layouts, allowing for a sharper image and therefore much finer tracks (I make 10 mil, 0.25mm tracks without a problem).

    the photo frame part is really a good idea!

    Here's a trick for the etchant bath. Lots of people make very nice setups with temp. control, aerators, etc. For a basic but not too basic setup I like to use a muffin fan from an old computer. Break off a couple blades next to one another so it is unbalanced. Place it underneath your tank. I use my variable bench supply for adjustable power but an old wall-wart would do. Secure the tank by placing heavy items beside all 4 sides so it can't vibrate off! Heat it with an incandescent desk lamp.

    This is an excellent tutorial on this topic. I have shied away from etching my own boards due to my fears of having perilous chemicals around my house (I have to do most of my hobby stuff in my living room & kitchen) e.g ferric chloride and the like. Yes, using stripboards can be tricky, but the main hassle with these is soldering one up that was copied from a breadboard - and the breadboard test wasn't a proper test to begin with...Thanks for the info, anyway.

    If you are wondering why he used red light when opening those PCB's is that red light has a longer wavelength (which makes the light less powerful), therefore it won't etch the photoresist.
    However, blue lights like fluorescent lights have shorter wavelength (makes the light powerful) therefore it will etch the photoresist.

    thanks now maybe i can start my plane project because i don't have to wait for 3 WEEKS for my circuit board to come so thank you very very much

  • @sagaertj
    @sagaertj Před 10 lety

    Some more hints: for etching i use 1/3 h2o2 (18% ) 1/3 water 1/3 hcl .
    Don't make too much since you can not store it, it etches a board in just less then a minute. You must do it outside since it produces Cl in the reaction.

    I remember doing this in Highschool. It's really amazing when you can take something as complicated (Or seemingly so) as a circuit board and make it yourself with relative ease.

    Nice vid! :)
    You can use a toner spray that spreads the ink so it covers holes that your printer hasn't drawn. or you can use nitrocellulose thinner. take a thin box, put the mask in and pour some nitrocellulose thinner on the box cover. The alcohol fumes will also spread the ink evenly along the printed mask.
