The days of autonomous cars and incorporating radar and lidar in the automotive sector are upon us. So, the first paper presents the reliability study of WLCSP for such applications. With the continued use of finer pitch components, it is imperative that we evaluate the SIR properties of fluxes to be used with the reduced lead spacing. The second paper presents a gage study to compare the SIR of various fluxes used in conjunction with fine pitch test patterns. The last paper investigates the effect of Ni contamination on the solderability within PTHs.
