ABSTRACT:
A method for manufacturing a silicon chip package for a circuit board assembly provides a package with a silicon chip and an array of first contact pads that are provided by a first conductive material. A plurality of second contact pads are provided from a gold material having a hardness different than that of the first contact pads. The second contact pads are soldered to the first contact pads of the package. A circuit board assembly is assembled by providing a circuit board substrate with at least one socket with contact pads. The second contact pads of the package are assembled to the circuit board substrate contact pads.
