Hi,
I am carrying out some tests using the laser image transfer method, where the image of a circuit is put on a PCB as an acid resist, so leaving the circuit in copper. My thread PCB by Laser transfer.
My method is a 'sandwich' of two stiff plates app 110x160mm bolted at the edges. PLATE-SILICON SHEET-IMAGE-PCB-IMAGE-SILICON-PLATE. The plates need to compress the silicon enough to give even pressure to the image, and be able to withstand heat up to perhaps 250C.
I am trying different methods of heating, this time I want to test microwaves. I've tried it with plastic and rubber bands, the band snapped and the plastic melted, but it worked. So now I need a better approach. (No metal)
Any suggestions, for materials for this. Obviously I don't want dangerous fumes.
