I would like to try using wax as a resist for etching PCB's. To do SMD's I would need to be able to burn lines in the wax with a resolution of 100 microns or possibly less.
Ebay has some cheap 808nm 300mW laser diodes that I was thinking about trying. My questions are; would it be possible to achieve the resolution I need with this LD and if so would it require a collimator? I can mount the LD at whatever height I need above the board.
