Voids are quite common. You just need to make sure that it is not excessive per your assembly criteria. Take a look at a D-pak under X-ray.

Are you running any type of vibratory wave on the Vitronics as opposed to the electrovert? How about any turbulent wave differences if any? The only time I have ever flooded boards in fixtures is when the seal is broken or run an excess amount of v

If these are these bare [or partially assembled] boards, baking probably will not hurt, as long as the bake is not excessive. If these are these assembled boards, baking probably will not accomplish much. What is the source of this water? If it's

I wonder if anybody could spec a conformal coating or simalar application, to protect PCB's at 90% humidity. Standard HPA from electrolube does not work if the humidity is in excess of 75%. Cheers
