How about making PCBs with Press n Peel film
I have successively used Press n peel to make at least 2 double-sided PCBs several years ago.
But over the last few days, I have been trying to do another PCB, but no success & don't know why it is not working.
I followed the Press n Peel instructions.
i.e. I rubbed the bare copper with steel wool, then washed it with soap & water, then washed the soap off and dried it with a lint free cloth.
But after much ironing, only a few slight traces of tracks were visible.
I also used a procedure I found on an electronics forum which is essentially the same but it uses isopropyl alcohol rather than soap & water. The result was slightly better, but certainly not adequate.
I really don't know why it worked previously but not this time. I used the same HP Laser printer.
I also heard that the PCBs can be made by simply printing the image of paper rather than the P n P film. But apparently it takes a lot of work to remove the paper. However, if it works, I will do it that way.
Any assistance will be appreciated.
