equipment: (in wet lab)
laminator
printer
4. TRANSFER
supplies:
scotch bright pad
PCB paper ( can use magazine paper)
copper PCB board
tape
scissors (cut your board and transfer to size)
water
paper towel
Sharpie marker (for filing in traces/touch ups on transfer)
steps:
step 1: prepare the PCB board with ScotchBrite
(in a circular motion scrub the copper until it is shiny) *no finger prints
step 2: lay artwork print out face down onto prepared PCB board (you can use a tiny bit of tape to tag the
layout onto the copper, but be sure to tape outside the parameter of the layout)
step 3: run PCB board with printout (face to face) through the laminator 2-3 times
=
step 4: let the water do the work (if using the PCB blue paper, it will release on itʼs own/ if using magazine
paper, you will gently rub the artwork from the copper)
* here we can check the transfer and use a Sharpie pen to fill in any minor mistakes. Check your work before you put it in acid, you may have to do this
process again if too many traces are broken or the transfer did not take.
