content: Good luckThere are a lot of channels out there but they all seem to lose the DIY/teaching aspect after some timeTry and focus on quality over quantity and you'll be on the right track in my opinion.Your video had a nice intro and you included some nice little details that were helpful to me so I'd say it's a nice start but as with anything there's always room to grow.Again there's no shortage of channels but if you focus on quality and do it for the right reasons I dont see you having trouble finding a nice niche for yourselfOn the other hand if you're trying to get rich off of add revenue it's going to be a long tough uphill battle and you might want to focus your efforts on a more lucrative arena other than YouTube.

content: I would have soldered the components in a different order: from the lowest height/profile first to the tallest last. It just makes things easier, because this way the components do not tend to fall when the board has its copper side up.

content: It might be helpful if you included links to the software you are using in the description, and perhaps use on screen text for important bits to re-emphasize key points (like your chemicals, ratios, temperatures, times, etc).Overall a good video.

content: In my opinion, this could be done cheaper and more safety. You can replace acid with sodium persulfate which is also cheap or even cheaper. Also, there's no need to use Kapton tape, basically. You can position it and with first touch the iron will make ink stick copper and paper together, it won't slip. There's also thing with cooling down ink with paper, too much temperature difference will make ink&paper shrink. Personally I'm putting toner-transfered PCB into 40 Celsius water with some detergent (to make water soft) when it's the same temperature as the water.In any case, it always takes a lot of practice and time to learn this

content: Haven't watched the video yet. But I started a YouTube channel as well (URL in sig below) and have posted 9 videos so far, and surprisingly, I've had no negative comments yet. Kind of weird considering the usual YouTube comments. I was all prepared to try my best to not let the negative comments bother me, and none of them came...

content: OK, watched DifferentCurrent's video. Very well done.My only issue is a thing that annoys me when I hear it -- please don't say "PCB Board."The B in PCB stands for "board" so you are saying "Printed Circuit Board Board." Just say "PCB" or say "Printed Circuit Board" or just "board." But when that's my biggest complaint, it means you have done a good job. And that is more of an OCD thing with me than a real complaint.I really liked the time lapse screenshot of the board layout with the voice over while it was happening.Of course, if you get many comments on a home made PCB video, there is always someone who asks why anyone bothers to make PCBs at home when you can order them from OSH Park for so little. But I think there is a time and place for both. For me, I think I'd go with manufactured PCBs if I am going to make more than one or two, or there are a large number of holes to drill.Do the Press and Peel sheets have a shelf life? I have a pack somewhere that I bought at least 15 years ago, used part of one sheet, and haven't used the rest since. I wonder if they are still good...Is there any advantage to using these chemicals instead of the usual Ferric Chloride etchant?I bought a set of PCB drill bits cheap from dx.com, and broke one on the second hole I drilled, and broke another on the first hole I tried. And I used a Dremel in a Dremel drill press just as DifferentCurrent did. Only thing was I was drilling into ABS plastic sheet instead of a PCB, but I didn't think that would be a problem. It's actually softer than FR4 PCB material.

content: Quote from: Carl_Smith on April 26, 2016, 03:54:39 amI do both, pretty much all of my mixed signal and RF unit testing is done on test jig PCBs I fab myself in the kitchen when the wife's not looking (DON'T let any ferric chloride get into your stainless steel sink or you'll find it's now a colander - don't ask how I know this). I go down to 0.5mm pitch and 0402, but it tends to be mostly single sided etching with a solid ground plane.For the system testing and above I get the boards fabbed by a board house.

You are able to do that with this method? I have a number of little boards I would like to build that amount to tests or fixtures. It would be nice to be able to quickly test a section of a high speed circuit. I think I might try this just to know for myself. There are some cheap PCB houses out there, but it takes a number of days. These little things could answer a question in a matter of hours.

content: My turnaround is half an hour, from opening the cupboard where the chemicals are, doing the UV exposure, developing, putting the board in the warmed ferric chloride, rinsing, removing the resist and rinsing again, putting all the paraphernalia back in the cupboard.Edit: Although I have a proper set of bubble etching tanks, I don't use them, it takes to long to set up for my transient kitchen facilities, and they're buggers to clean out. All my chemicals are in old translucent plastic takeaway containers with lids, and they in turn are stored in a plastic storage box again with a lid, so any spillages will have minimal if any impact.Possibly not strictly conventional, but I warm the premixed ferric chloride in the microwave. Again, don't tell the wife. I am sure there are million reasons not to do it this way, but that's the way I do it.I use an old Hp1320 1200dpi laser on Mega Laserstar transparency which is like translucent thick tracing paper.The key is once you have a process, stick to it, but it took many failures for me to get a process.Coincidentally my process has eveolved to very much resemble Mike'shttp://www.electricstuff.co.uk/pcbs.htmlbut I rarely need to do double sided etching for the unit test boards, favouring instead a solid ground plane and any extra unrouted lines I ensure are low speed and manually add using Kynar wire, but that's the nature of RF and mixed signal anyway. I generally copper pour ground on top too as well a bottom and use tiny 0.6mm OD copper rivets for the ground vias.

content: That an excellent encouragement - the words and the resulting pics. Seems like you have sorted the process to be worth it in terms of time. So many times I just want to take a portion of a circuit and get a sense of how well it works. With power or high-speed stuff a PCB is the only practical way to shake down the details.Did you do the holes with a manual drill press?

content: Quote from: rx8pilot on May 14, 2016, 01:32:01 amYes I use a manual drill press and largely stick to 0.7mm/28mil bits for the vias, and a bit larger for the headers. 0.7mm seems about the smallest I can go without an armageddon of broken bits: I am not a machinist by any measure, I am sure if you have skills in that area you can do much better. For proper boards fabbed at board houses I use 0.3mm/12mil, and sometimes 0.25mm/10mil but it's more expensive.https://www.megauk.com/pcb_drilling_machines.phpI keep meaning to sort out some kind of vacuum attachment to get rid of the swarf because you end up having to clean the board of drilled out dross very frequently.The best thing about surface mount is, of course, there're much fewer holes to drill! In RF, hi speed and mixed signal though, frequent ground stitching vias are essential irrespective.
