摘要: In ball-grid-array (BGA) package technology, the oxygen concentration in flow process predominantly influences quality of solder conjunction such as oxidation causing aged effect and inter-metallic compound. addition, flux assistance is also a key factor determining adhesion ability between carrier HBGA substrate ball. Using temperature cycling test, shear test drop to distinguish for lead-free balls on assisted with several fluxes, optimal recipe was achieved. The soldering performance impressive.
