OK so you're stuck with gold. Not all that bad unless you're paying for it. Gold is very flat compared to HASL, so you should have no problems printing. This should lead to good placement as well. But after oven you mat have a big contrast betwee

not just speed, looking to reduce down time on having to re-do boards from bad stencil screening. also, the accuracy of placing solder paste down on PCB's. why would you want an employee spending so much time aligning fiducial marks from panel to pan

See, now you know how you got the job!!! ;-) Assuming you mean solder mask, that stuff is designed to be tough to remove. It�s an epoxy meant to protect the board features from the ravages of board fabrication and everyday life. Your choices are:
