Your warpage problem could be caused by change in: * Multilayer board construction (not homogeneous or unbalanced - too resin rich or poor) * Supplier process capabilities (lamination cycles) * Material selections (usually cheap and dirty), etc.

Hi, I am also facing the same probelm. I assembly a substrate with a thickness of 0.30mm and the board warp after reflow. If I bake the substrate at 125 Deg C for 2 hours will it help to solve this problem? Thanks

Another area to look is on any breakaway. If they did not add copper to breakaway, it can warp your board if long enough. Seen it happen many times.

It could be as simple as a new operator in lamination lay-up who is laying up 90 degrees against warp and fill.
