Does anyone have any experience, good or bad relative to exposing OSP coated
products to thermal cycles in Nitrogen ovens. We are talking about exceeding
200 C while the product in is the oven and it could be multiple cycles.

We've experienced problems with second side soldering with OSP coating in
non Nitrogen ovens when producing surface mount products. This was overcome
with the use of a stronger flux system, but the question is would the
introduction of Nitrogen reduce or eliminate and solderability issues
relative to the product being processed.

Any and all comments would be appreciated
