Over the past several months we have experienced intermittent problems with wave solder voids on PCBs coated with OSP. We suspect variation in the OSP application process, or oxidation of the surface due to insufficient or degraded OSP. Is there a me

OSP board finish is the issue. With OSP microBGA board, we need to have enough paste (enough flux) on pads (small pads on BGA), also we need to have strong, more activate flux to get rid of Preservative layer on top of pads. In this case, the OSP did

. This plating also covers the copper layer, protecting it from oxidation. Many finishing materials currently exist, each with its own set of trade-offs

. Without a nitrogen blanket one can expect heavier oxidation of the surfaces to be soldered. In addition, the no-clean fluxes are not as active as the water soluble fluxes, therefore reducing the oxides is more difficult
