Abstract :
Paper deals with results of solderability testing of printed circuit boards (PCBs). The target of solderability testing was an assessment of cleaning substance influence on solderability. Several types of cleaning substances were used for PCB cleaning. Isopropylalcohol and special cleaning liquids were applied on PCBs before solderability testing. These cleaning liquids shall clean up the surface of PCB from impurities. Most often used lead-free surface finishes were tested (coupons of printed circuit boards with surface finishes galvanic tin, immersion tin, ENIG (electro less nickel immersion gold), OSP (organic solderability preservative) and pure copper).
