Quoted from barakandl:going and redoing every IDC plug is probably overkill. Change the high current carrying and any suspect/problem connectors to crimp style.
Better use of your time is changing the round headers to square ones, but again probably overkill and takes good desoldering gear. The round original headers are usually cut nearly flush to the solder side of the board making the solder more likely to crack. Plus the round shape of the posts is not ideal.
Yes. They definitely cut those connectors too flush. I usually pull them all out, clean them, and then use a spacer that I 3D printed to use a use to push about 1/16" more of the pin through the shell. Worked out great. Good solid connections around the board. I just put all new connectors on the 40-pin interconnect.
