There are solder pastes that seem to give you less voiding. Currently we are using Kester ,water soluble paste that gives us pretty good results on BGA's up to 0.5mm pitch. Stencil design was a challenge but we are getting consistent results . Here

Sorry it has taken me so long to respond. I got pulled off onto other projects and was not able to work on the solution to the problen until recently. The solution we have come up with is to change from no-clean flux based solder paste to water sol

We use water soluble paste, Kester R560. These units are wave soldered and cleaned in an Electrovert Aquastorm water wash with a 3% Kester saponifier solution in the first stage.

I using water-soluble solder paste, the solder paste recommended, the peak temperature is 215 deg C, the dwell time above 183 deg C is 60-90 sec. **How I can do, the flux in solder paste is active enough to remove the corrosion on the Cu leads to get
