Abstract:
A method for mounting an integrated circuit package on a substrate, wherein the integrated circuit package includes a first lead being nondeformed and connected to a first land for mounting on the substrate, a second lead being deformed and connected to a second land for mounting on the substrate, comprising the steps of:supplying conductive material on a land on the substrate wherein an amount of the conductive material larger than that of the first land is supplied to the second land; and melting the conductive material supplied to connect a lead in the integrated circuit package with the land wherein the conductive material molten on the first land extends in the vertical direction with respect to the substrate with a first height thereby connecting the first lead with the first land, while the conductive material molten on the second land extends with a second height higher than the first height due to surface tension thereby connecting the second lead with the second land.
