Pb-free soldering copper alloy plate with Sn plating for PCB male terminal which is excellent in resistance

摘要

PPROBLEM TO BE SOLVED: To produce a PCB male terminal excellent in Pb-free solderability and having sufficient strength and electric conductivity from a copper alloy plate on both sides of which Sn is plated before blanking. PSOLUTION: The copper alloy plate with Sn plating for PCB male terminals for producing the PCB male terminals has Sn plated layers on both surfaces and has shear-cut end faces by press blanking on both end faces. The copper alloy contains 0.05-2.6 mass% Fe, 0.01-0.2 mass% P, and one or two of 0.01-5 mass% Zn and 0.01-2 mass% Ni, and the balance Cu with inevitable impurities. Alternatively, the copper alloy contains 0.01-2 mass% Ni, 0.01-0.2 mass% P, and the balance Cu with inevitable impurities. PCOPYRIGHT: (C)2010,JPO&INPIT
