The specific answer depends on what your specific application includes. #1: What are you removing? (solder paste, adhesives) #2: What are you cleaning? (stencils, screens, misprints, pallets) #3: What type of machine are you using? (Spray-in

We have struggled with this as well. Basically, we have a consistent rotation for all packages of the same type, but I don't think our rotation has anything to do with the actual rotation that the PnP equipment actually wants to see. I believe our

Hi A lot of good answers. "No verification was done on the part as it was deemed to be a "straight replacement". Sound familiar?" Yes this sounds familiar, yet I am never sure it is a new supplier or component problem. It could be that the old par
