Why don't you look into a BotFactory Squink? It can deposit solder and pick-and-place. It prints conductive ink for the traces too. $3K is probably spot on for your budget. Check out http://www.botfactory.co

I am looking for Permanent non conductive ink (Black and white) to mark PCBs with. I am also looking for a method to apply the ink (stamp) in letters 0.08 high. I need to stamp the board in two locations the first is 9 characters long (Numeric) and

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

Hi GSX, just and FYI on why you are seeing a difference per lots. Carbon Ink is Not used on a steady bases by most manufactures, and shelf life of the Carbon ink is fairly short, my guess is what they are doing is adding thinner to the carbon ink t
