For example, in the BGA world, the thinning of substrates and overall package thickness has led to increased package warpage during the SMT process, and hence the need to adjust stencil openings. In some cases the package may tend to bend away from the PCB during SMT reflow leading to an open, and by increasing paste volume

The three distinct processes that occur during annealing—recov-ery, recrystallization, and grain growth—are described as follows. Recovery. During recovery, there is a rearrangement of ...
