Anyone pre-baking prior to the wave with OSP on the boards. Time and Temp? Seems I heard about an oxidation of the Cu under the OSP, or was the T & T too much? Question comes up because of the necessity to bake things such as Thermount boards prior to any temp. stressing. Thanks, Neal Preimesberger, HMSC Tucson. 520-794-1030 [log in to unmask]
