hello, tin snips are good, you can also score the board with the blunt side of a industrial knife cutter then break it apart by placing the board on a desk and place it on the edge being separated and push down to snap it. All the best George

Hi.. Nice video... But don't you think that some tracks for the mosfets or transistor are too thin as they supposed to work on higher current... Please let me know if I am working...... Thank you..

It's not an ideal layout, but it was meant as a quick prototype. For real world use I'd go with a two-layer board with 2oz copper (or better.) I should have also use polygons instead of those thick traces.

Thanks. The ferric chloride and Liquid Tin are saved and reused. The soldermask developer and photomask developer are just diluted with more water and poured down the drain. If you are going to be making more than a few boards a year, you should probably look into a better way.

Hey, thank you for the video! I have a question I hope you could answer it. I have some transparencies but the contrast I very low and the print is not good. Can you please tell me if you had problems with transparencies not being contrast enough? I wonder if this is a problem with my toner or the transparencies that I use. Thank you

I set my printer driver to print very dark (which uses more toner) and it works nicely.

@@upgrdman hey Thank you for the reply. I guess either my toner or the transparencies are of poor quality because I too use the highest density possible but the results are poor. I guess I will stay with toner transfer until I find a way. I used vellum paper with good results but it is not forgiving at all. Need to be in absolute contact otherwise the exposure is not sharp at all. Thank you again.

I've never done DIY double layer boards, it seems more effort than it's worth. Past a simple one-layer board, I would just have some boards fab'd by one of the cheap vendors in China.

Giuseppe De Feo Hi. I don't know the details, but this is the light I use: www.mgchemicals.com/products/prototyping-and-circuit-repair/prototyping/exposure-kit-416-x/ It's roughly 6" (150mm) from the surface of the PCB.

upgrdman i have a cuestion, Which is the difference between POSITIVE DEVELOPER and SODIUM CABONATE , because im using the second one, in the process protect the nets and pads, and after remove the copper, but the copper is removed from the pads and nets.

How did you print your copper layer on glass sheet? by laser printer? It won't get damage because of high temperature?
@upgrdman

+Mostafa Najmi Hi. It's printed on a thin plastic "transparency" (the kind used for overhead projectors.) I used a laser printer, but inkjets should be fine too. If you want fine traces like i used (10mil and sometimes even 6mil) you need a printer that does at least 1200dpi. 600dpi is not enough.

Can anyone tell me if a Tinn solution would work on gold-plated traces? Please ignore the fact that its stupid to tin plate over already gold-plated. I would assume it would work (cause copper and gold are chemicaly very similar), but I would like to be 100% sure before buying tin plating solution

dana miller Hi. Yes, it is reusable and it lasts a long time. I bought a 500mL bottle around 3 years ago, have tin planed maybe 10 square feet (almost 1 square meter) of boards, and it still works like new.

upgrdman Hi upgrdman, What about the developer; is that reusable too?You had the developer premixed on a container with a lid; is that because you store it there for future uses? or is it just like you said it, premixed just for this video? Thanks.

Tony caruso Yes, that is reusable too. I typically reuse the developer until it becomes difficult to clearly see the board when submerged.
