Hi Gary,
You know the saying about old dogs and new tricks?
Anyway, I re read what you wrote:
"I print out the images on glossy paper with a laser printer and put the printed sides inwards, carefully line them up with a bright light behind and staple them together. Cut the PCB to size without touching it with your bare hands at any stage prior to heating, scratch up the surface with 180 grit sandpaper and then clean with acetone. Once dry (wet acetone will dissolve the toner) put the PCB between the sheets of paper and run through a preheated laminator at full temperature several times. Then I put the PCB in the oven at 180 for 5 minutes while the laminator is on. Take it out of the oven and straight through the laminator a couple more times. I know of at least one person who has done this with an iron rather than the laminator. The baking in the oven is important to get a nonporous layer of toner."
Question 1, what kind of glossy paper? I do not have any.
Question 2, when you say "take it out of the oven and straight through the laminator a couple more times", would that not ruin the image by scrubbing from the hot rollers? Or do you have the board between to clean sheets of white paper then?
BTW, I clean my boards with the fine ss scrubbing pads, the soapy ones, under running water. They come out very clean and no copper gets sanded off. Then spray with PCB cleaner and wipe off any pad residue with a paper towel.
I am weary to use acetone after the etching to get the toner off, always did that with the ss pads as well.
