Title: Surface-treated steel sheet for high-performance lead frame having excellent corrosion resistance and solderability
Inventor: HIGUCHI YUKINOBU
IPC: C22C38/50
Filed: 1987-12-22
Abstract: PURPOSE:To provide the title surface-treated steel sheet which has excellent platability and solderability and is further provided with corrosion resistance such as rust resistance in combination by providing coating layers of an Ni-Fe alloy, Co-Fe alloy or Ni-Co alloy respectively specified in the deposition per face on the surfaces of a Cr- contg. steel sheet having a prescribed component compsn. CONSTITUTION:The Cr-contg. steel sheet contg., by weight %, <=0.06% C, 0.005-0.10% acid sol.Al, 3-20% Cr, and 0.03-0.8% >=1 kinds among Ti, Nb, Zr, and V is prepd. The coating layers consisting of the (10-90%) Ni-Fe alloy, (10-90%) Co-Fe alloy or (10-90%) Ni+Co>-Fe alloy are provided at 100-3000mg/m<2> deposition per face on the surfaces of said steel sheet. Since the coating layers are alloyed with the Fe by the Ni and Co, the potential difference from the base steel sheet is lower than the potential difference of the plating layer of the Co metal alone. The preferential corrosion of the underlying steel sheet of the plating defective part and the easy tendency to formation of red rust are thereby prevented; in addition, the coating layers themselves prevent the corrosion of the underlying steel sheet. The corrosion resistance including mainly the rust resistance performance is thus improved.
