Hi technos, I have run into trouble with a PSS connector from Samtec. Before reflow it is OK, can't see any cracks in all the parts I checked in the tubes, but I get major cracking of the pins, randomly, after reflow. Please see the picture at http://www.stevezeva.homestead.com/files/crackedpin.jpg, another friendly support from Steve G. What could cause that? It is an established product, we already built thousands with no trouble. Could it be the reflow recipe causing this? Maybe it was borderline and for some reason it is too hot now. It is not the joint, but the actual pin that cracks. Actually, can the thermal excursion give this? Or is it some tension built in the pins from bending at the connector manufacturing level, maybe the material was tempered somehow? Any clue would be appreciated.
