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

Hello all, these days I've met an OSP board testability issue. 1.OSP board 2.Solder paste:Kester R244 no clean paste 3.Print solder paste on test pad. Issue: There's brone(light yellow)flux residue on test pad,and the probe can't penetrate the residu

This issue is not "testability of OSP board". It is "testability of nc flux residue". Kester [or some other flux suppler] can probably recommend a flux residue that is more probeable. We have talked about the problems with probes getting gummed-up
