Defects Contrast between Wave Soldering and Reflow Soldering

WebDuring reflow the solder balls are self-centering (up to 50% off the pad), thus reducing placement problems during surface mount. Normally, because of the larger ball pitch (typically 1.27 mm) of a BGA over a QFP or PQFP, the overall package and board assembly yields can be better. WebAs the soldering method for QFN package that is one of the surface mount devices (SMD), reflow process is recommended generally. Reflow process is as follows. Firstly solder paste is printed on PCB, then surface mount devices are mounted on the PCB, and then the PCB with SMD is soldered by the heat of a reflow oven. This travels of guru nanak
