. 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

. The reason we do not twist wires to create splices is that it may affect the reliability of the solder joint. Over stress may crack and separate this type of splice
