Hi DaveF already gave you some fine answers. Yes I have seen CNC routed copper PWBs, and the literature is filled with many unique trace types including laying of fine wires on a board or embedded. You wanting .15mm, and I am guessing, low resistan

Questions are: What is: * Purpose of this PCB ink? * Meaning of 'non-conductive?' * Temperature of your laser? * Reason solder mask is not the product of first choice? * Space of the unsoldered region located between soldered areas? * Maximum cure te
