Abstract:
1. A method of forming an interconnection board, comprising: forming an interconnection board on a plate; and removing said plate from a first side of said interconnection board thereby exposing at least one external electrode pad having an exposed surface level with said first side so that said first side and said exposed surface form a single flat plane; forming a supporting plate having a plurality of holes corresponding to the exposed at least one external electrode pad of said interconnection board, into which a plurality of external electrodes are inserted, so that said supporting plate extends in parallel to a second surface of a buffer layer to form an inter-space between said supporting plate and said second surface of said buffer layer; and forming a supporting sealing resin material which fills said inter-space and surrounding parts of said external electrodes so that said supporting sealing resin material is in contact with said parts of said external electrodes for supporting said external electrodes, wherein during the forming of said interconnection board, said interconnection board remains fixed to said plate, and during the removing said plate the exposed surface of said at least one external electrode pad remains exposed.
