Abstract :
Flash gold with nickel and gold plating is a low-cost technique in PCB finishing, frequently used in the production of toys. The quality of plating has become one of the concerns for the performance and reliability of solderability. This study investigates the solderability of PCB produced by flash gold finish and traditional nickel and gold plating finish. For this purpose, solderability tests have been conducted. The test results with both techniques of plating layers are analyzed and compared. Their impact on solderability of PCB is discussed.
