How to make a double sided circuit board using the toner transfer method - Part 2 of 2

I use the Pulsar PCB "Fab-In-A-Box" Kit http://www.pcbfx.com/ to make my own double sided PCB. I made this video for my lab http://www.icehockeyscience.mcgill.ca which is why it is so long but I don't think its a bad idea to share it with you in full length as many videos just jump through the process very quickly. I am a completely new at this as this is my second board I've ever made. I'm not a circuit guy but needed a board for my research project in biomechanics so I went out and learned. Please feel free to comment with improvements or suggestions on my methods but provide some reasoning if you do.

Thanks and good luck with your boards!

what was the point of the green stuff???

[0ak1e]

@1787dude The point of the green film is to add an additional layer of protection against the Ferric Chloride etch. You can do it without using the green film, but the quality of your traces will not be as good.

@0ak1e what is the name of that green film?

[0ak1e]

@vze4p6c2 It's called Toner Reactive Foil (TRF), I think you can buy it from Pulser directly, however, I got it from Abra Electronics. Good luck!

What thickness of pcb board are you passing through the  GBC Laminator.

[0ak1e]

@bayhoecott This was one of the sample boards that came in the PCB Fab kit. It was 1/2oz Copper, .032" thick. The etching really was much faster with the 1/2oz copper. I tried another double sided copper from a surplus store and it took almost 30 minutes!

nice job ! very clean and pure

@0ak1e thanks, i am just getting into this. :D

thanks for this video i need to know about the green paper using what its name pls say

[jjppmm29]

why dont you use sewing pins to line it up

[zanak]

you can cut the time by 2 if you etch both sides same time. the way I do it : cut you transfer paper and keep 2 or 3 inches of white space . line up your both faces using light. holdem tight together and put a small piece of tape just in the top of the white space to keep them lined, place the pcb between the two pieces of paper, heat transfer and etch, I've made some tiny double sided boards with fine traces (10 mils) using this method . thanks for the video
