I am seeing poor quality solder joints, mostly on 0402 components. The problem is that while the pad on the pcb is getting fully wetted, the solder is not flowing up the sides of the 0402 component, i.e. the 0402 lead is somewhat de-wetting. The re

Try these things: 1. Do a function 30....your nozzle height should consistently be around 200 +/-20....but whatever number it does find it shouldn't change. (with nozzle on) 2. Most times its the z-bellows....an old z bellows that has a worn out spri

If we understand correctly, your SMT solder connections remelt when passing through the wave solder machine and your QA-people don't like it when that happens. It's nice not to remelt this solder, but as long as the board meets your acceptance stand

There should be a regulator to adjust the puff off on the inside left back panel. Remove the left side cover to get to it. Write down what its set at prior to adjusting it. I have also seen this problem caused by water in the system. Make sure that y
