Hi Ron, Your question really opens up a "Pandora's box", but when you say you're not able to print perfectly, what is it exactly that you mean? Is the print lacking volume? Is it mis-registered? Are you bridging? Also, what printers have you used? Do

Yeah, them soldering machines sure got some demons in them...My waves used to get blamed for wrong polarities all the time. Sneaky little devils used to pull components out of the boards, flip them around, and get the pins back in the holes while

I have done both. If you have a line that runs both sides in none pass, running the adhesive side first allows you to have one less machine or station for board flipping. If you have to move the board from one line to another, or back to the front
