ABSTRACT:
To mount an LSI package to a wiring substrate, input/output pins for the LSI package are arranged on the wiring substrate beforehand. After solder has been fed to input/output pads formed on the package, the package is mounted to the wiring substrate by soldering the input/output and pins. The method allows the package to be easily removed from the wiring substrate if only the package is heated, and therby enhances repairability.
