"Good morning. I made the following formula to make printed circuit boards, and I want to know if I am the first person in the world to use this method?"



"Or in other words, have you seen this method before?

I use a modified laser printer (with the fuser removed) to print onto polyester sheet, then apply high voltage to the bare copper board to transfer the unfused toner from the polyester. Finally, I use solvent vapors to fuse the transferred toner to the board.
thanks

 

Hello,

Toner transfer using a modified laminator has been used before:

Your method sounds a bit more trickier, as the toner is still loose on the foil.

At first, I wanted to modify a laser printer to allow the board to feed directly into it. However, fortunately, I didn't rush and asked myself the following logical question: "Why aren't there printers on the market that operate on this principle?" I tried to answer this question and concluded that the reason might be that the boards are rigid and not flat, which increases the likelihood of scratching the photoconductive drum

 

There are, or at least, there were, flat-bed printer/plotters that could handle flat sheets.
AND a common method was to use a laser printer and the do a heat transfer to transfer the ink to the PCB as etch resist.
