Help with PC boards
« on: June 03, 2017, 03:34:02 PM »

Good day,

I have begun experimenting with a view to making some printed circuit boards, using the "toner transfer" technique. Initial attempts using the wife's electric iron are encouraging, but the idea of applying heat and pressure this way seems to me rather woolly! Does anyone out there have some idea of the temperature required to melt the toner onto the copper? I am looking at maybe clamping everything together and heating it in the oven. Any and all info / comments / suggestions most gratefully received.

cheers John K.

There's loads of advice on Youtube. Best I have seen is to tape your design to the pcb then run it through a heated laminator several times to transfer the ink. I don't know how hot the iron is but I would be careful of overheating the board and detaching the copper from the bonding agent holding it to the grp board.

Yes - precisely the sort of thing I hope to avoid.

A domestic iron with temperature control is probably the simplest and safest way to do the job.  Just a question of selecting the right setting then applying heat for the right length of time.  There will probably be enough variation in temperature characteristics between makes of PCB to render any recommendations regarding actual temperature fairly meaningless.
