| | We are wave soldering some fabs with a lot of unmasked trace area along the edges. The trace area is solid copper covered with tin / lead, no masking, no components along the edges, same on solder side and component side (goofy board design). I

'Hege is checking in for the DRS25 by Air Vac. Forced Air Convection reflow, and huge heating capacity for bottom side, ensuring minimum Delta T across the PCB during the process. Have 3 of these machines constantly in use for the last 2 and a half

What exactly counts as "always on"? Our ROHS wave solder machine is always on during the week but the pot shuts off at the end of the shift and turns on early in the morning so that the solder is melted before we get to work. It is only using a small

It sounds like you will need to pre-heat the aluminum beofre using even a laser to solder this type of application. While lasers are great for many applications, especially those that have challenging keep out areas, thermal mass issues (with approp
