I have this board that is 18 by 14 though hole and SMT. After reflow the board
looks good not warped. Once assembled and sent to wave the board warps, only
around the PCI connectors. It warps so bad I don't have any lead protrusion. I
have tried to run this board many ways fast slow and minimal preheat. I still
have this problem. Has anyone ran into this problem before? Is this common
around PCI connectors? I recall this happening once before many years ago, I
resolved it by tacking down the edge and middle of the connectors then
masking. Is this the only fix? Any other suggestions
Thanks in advance
