presence of micro cracks and surface defects such as scratches and chips. In these materials, the high level of stress at the tip of a crack cannot be relieved by plastic flow and so even very small defects can lead to low failure loads

. An opposing school of thought was that voids act as crack arrestors, which improve solder joint life. The root cause of voids in BGA solder joints is well understood by the electronics industry with a number of papers published on the topic [1, 2, 3]. R
