Hi Craig,

One rework cycle for a BGA means desoldering, cleaning excessive solder from the BGA-pads, reballing and resoldering, all this in addition to the original soldering cycle.
I don't think there's any manufacturer that will guarantee that their BGA's will survive this.
In practice I've had some good results (meaning: the board still worked) with BGA's that were subjected to all these cycles for 4 or 5 times.

Kind regards,

Technetters,

Any recommendations on maximum number of rework cycles for a Plastic BGA?

TIA,
Craig
