Abstract :
Paper deals with results of solderability testing of Printed Circuit Boards (PCBs). For measurement was used one of the solderability evaluation methods known as the wetting balance test. The wetting balance test measures the wetting forces imposed by the molten solder on the test surface as it is dipped into and held in the solder bath as a function of time. Paper will present the comparison of results of printed circuit board solderability test with preheating in agreement with IPC/EIA J-STD-003A, with IEC 60068-2-54 and with hot air double-sided preheating. This comparison will be also made for several lead-free surface finish types. It was tested printed circuit board coupons with surface finishing of galvanic tin, immersion tin, ENIG (electroless nickel immersion gold), OSP (organic solderability preservative) and pure copper.
