| I recently switched from solder paste in 500 gram jars to 500 gram tubes. I did this to try to limit the time the paste is exposed to the room environment. But we have a need to clean the stencil every 4 - 5 boards which means taking the bulk paste

Hi Carol- What you are asking for can be done. Variables you must account for include the paste viscosity, dispensing head speed, dispenser height relative to board surface, and needle size. You can use most any semi-automated system such as Camalo

Recently, there has been an upsurge in the Pin Hole/Blow Hole problem in our wave soldering process. We are baking the PCBs for 2 Hrs. at 125 degree C. The Wave Soldering profile seems to be O.K. Still the problem is persistent. Can somebody help
