In a previous job, we had torque off requirements for different sized components for our screen print adhesive (non-conductive in our case). We used a torque watch that would measure max torque, so we could test production boards, shear testing was

Having solder flow issues on gold pads. Issues started when supplier switched adhesive tape used to cover pads during varnish process. By running SEM/EDX and XPS analysis it has been determined that the new tape leaves behind a thicker organic residu

We agree with the points made by ScottE above. Additionally, most printers are not heavily loaded. So, you wouldn't have to buy another machine, give-up floor space, purchase and store peculiar tooling, etc. We think Darby does pin transfer. Maybe h

I'll chime in here as well. If you have adhesion problems, 90% of the time it's contamination on the substrate (soldermask, flux residues, cleaner residues, etc.). Like Dave said, omega meter is a test for gross cleanliness, and it's OK for process
