We have tried the BGA replacement two to three times on the same PCB. And we found it reliable. The only thing that is to be considered to have proper removal of BGA in order not to damage the PCB solder pads.

Maninder Singh, Deltron (A Division of CDIL), India
At my company we qualify PCB suppliers in part based on HATS or IST via reliability results. We specify 6 preconditioning cycles to simulate assembly processes. Our reliability test results, then, are only valid up to 6 thermal cycles.

As Mr. O'Brien points out, a board with one reflow cycle has margin for only one BGA replacement. So we limit our assembly suppliers to 6 thermal cycles at any one site, but only one BGA replacement.


Jimmie King, GE Healthcare
All depend of the board finished. We are using AgIm and ENIG-Au/Ni we reworked Ceramic BGA's three times on AgIm boards and five times on ENIG-Au/Ni finished. The BGA removal profile is crucial in order to not damage or burn the PCB lands.
