Ball Grid Array (BGA) Packaging - Intel

During reflow the solder balls are self-centering (up to 50% off the pad), thus reducing placement problems during surface mount. Normally, because of the larger ball pitch (typically 1.27 mm) of a BGA over a QFP or PQFP, the overall package and board assembly yields can be better. From a performance perspective, the thermal and electrical ...
