Tape carriers have been used as BGA substrates because of their thin, fine circuits and high manufacturing accuracy. Electroless gold plating on tape carriers has become required. Electroless gold plating tape carriers having good gold wire bondability and ball solderability are being developed. We studied the influence of electroless gold plating thickness on wire bondability and ball solderability, with the following results: (1) The pull strength of gold wires on tape carriers with 0.2μm and over gold plating thickness was 0.07N or more. (2) The shear strength of solder balls on tape carriers with 0.2μm and below gold plating thickness was 3N or more after heat aging at 150°C for 500h. (3) Tape carriers with 0.2μm gold plating film had good wire bondability and ball solderability.
