The mini-BGA was to be smaller than the standard BGA and larger than the micro-BGA. The last I heard there will be no mini BGA but companies such as Tessera, AMKOR-ANAM, etc. will go directly to supply 0.020" center to center pitch micro-BGA's. You

Having some issues with our GSM picking parts that are delivered by the PTF off center; and wondering if there's a relatively painless way to calibrate where the head goes to pick the part on the belt. Near as I can see, the PTF is picking the parts
