There is no real reason why you shouldn�t use your current paste. Paste for printing usually is a coarser mesh than paste for dispensing. Dispensing paste is more expensive, because of the mesh and the packaging, but that doesn�t matter now. Compa

We do this quote often with our older Summit machine. there are a few ways to do this. all of these are assuming you have parts on the boards already and are working around them. 1- if you have a good tech that can add solder to the pads on the PCB a
