Conductive connecting pin for package substance
A package substrate 310 incorporating a substrate provided with a conductor layer 5, a conductive connecting pin 100 arranged to establish the electrical connection with a mother board and secured to the surface of the substrate, wherein a pad 16 for securing the conductive connecting pin is provided for the package substrate 310. The pad 16 is covered with an organic resin insulating layer 15 having an opening 18 through which the pad 16 is partially exposed to the outside. The conductive connecting pin 100 is secured to the pad exposed to the outside through the opening with a conductive adhesive agent 17 so that solution of the conductive connecting pin 100 from the substrate occurring, for example when mounting is performed is prevented.
