what we are getting is open circuits not every BGA is failing we use Humiseal 1A33 and currently there is no masking instruction for around the BGA

We doubt that Humiseal 1A33 is causing opens in your assemblies. We'd guess the opens occur earlier in the process, but are not hard failures. So, you pass your tests. When applied, the conformal coat flows into the gap in the ball crack and insulate
