I have not done pin in paste in production quantites, but speculation is always a blast so; OA fluxes are active at room temperature, they grow 'fur' with humidity if not washed off, great stuff for soldering, nasty stuff for reliability (if not rem

80%. There are too many factors at hand to point the finger yet. We need to build a truth table and dot the i's and cross the t's before stepping up to Goliath (Samsung). Is you placement guranteed good? What x-ray have you used? Are your fab.'s know
