发明名称 Multilayer circuit board with repaired I/O pin and process for repairing I/O pin on multilayer circuit board.
摘要 <p>When an external connection I/O pin which is formed on a multilayer ceramic circuit board is broken off together with a part of a ceramic substrate, an electrically conductive adhesive is filled in the area where the I/O pin broke and was removed, and together with standing a new pin in this place and connecting it electrically, the new pin is bridged and secured to the surrounding I/O pins using a fixation plate. In so doing, it is possible to restore the broken I/O pin to have the same electrical and mechanical characteristics as before. <IMAGE></p>
