OSP finish and Omnix 5002 solder paste(SnPb) | 14 May, 2010

I attached a RX picture. A lot of voids and micro balls arround the flux residue. What do you think, relow temperature reflow or OSP poor weeting.? I appreciate your comments. Thanks,

We'd expect both OSP poor wetting and improper reflow recipe to show-up in more places than just this one component. But if those are the only choices, we'll go for 'wrong solder paste.' Ooops, that's not one of the choices. Ok, OK, we'll take poor reflow recipe.
