pcb-printer: Experiments

  • Use etch-resist ink as solder mask
    • can you solder using a soldering iron?
    • can you solder using the reflow oven? (might get too hot)
  • Get etch resist to NOT FUCKING FLAKE OFF THE STUPID PCB DURING ETCHING GRAAAAAAHHH! *rage*
    • RESULTS: Use Fe3Cl, not NaPS. All other attempts led to epic failage.
    • Tried a couple of curing temperatures (temp setting on reflow oven) and times, here are my results:
100 °C 150 °C 170°C 180 °C 200 °C
4min FAIL! FAIL FAIL OKish
6min FAIL FAIL
8min FAIL FAIL OKish
10min FAIL
  • „OKish“ means the resist still flaked off, but stuck to the board relatively long.
  • An attempt to print on a pre-heated PCB and curing for 4min at 170 °C gave the best results so far (though not perfect), but the hot PCB warped the plastic carrier beyond repair =( A routed aluminium carrier with integrated heating could work.
