I just ordered this adhesive copper foil sheet and this adhesive Capton tape sheet to try an experiment making Flexible Printed Circuits (FPC), multilayer PCBs, and multilayer FPC. In my mind, I can throw either/both of these sheet materials into my wife's Cricut vinyl cutter and cut out circuits in the exact same way it cuts out vinyl logos.
1. Stick Capton sheet to mat, cut sheet (through holes and pads) apply transfer tape, weed out cut area, apply to <something>. This will serve as solder mask. Remove transfer tape.
2. Stick copper sheet to mat, cut sheet, apply transfer tape, weed out cut area, align & apply to capton sheet from step 1. Remove transfer tape.
3. Stick Capton sheet to mat, cut sheet (through holes & vias), apply transfer tape, weed out cut area, apply to copper sheet from step 2. Remove transfer tape.
4. Stick copper sheet to mat, cut sheet, apply transfer tape, weed out cut area, align & apply to capton sheet from step 3. Remove transfer tape.
5. Stick Capton sheet to mat, cut sheet (through holes & pads), apply transfer tape, weed out cut area, apply to copper sheet from step 4. Remove transfer tape.
If you're just making a 2-sided FPC then you're done. Or, keep stacking sandwiches of capton and copper sheets until you get bored. You could start with a sheet of capton like I described above for FPC (you will end up with one sticky side you might want to clean the adhesive off) or you could start with a regular PCB. Do your first side with normal methods (routing, etching, UV, whatever) then start layering capton and copper.
What do you guys predict? Will it work? Or will it suck?
