Surface Mounting is the fastest growing technology in electronics today. This is due first to the great potential for assembly cost savings generated by the increase of PCB component density, board surface utilization and routing density, and secondly, to the elimination of board damage factors such as fiber fracture, friction forces of pin insertion or trace distortion.
Certainly, solder joint reliability issues increased with the shift of the through-hole towards re-flow technology. Solder joint robustness characteristics decreased and it is usually much more difficult to maintain, especially from the standpoint of the CTE. (Coefficient of Thermal Expansion) ...
