METHOD FOR MANUFACTURING DOUBLE-SIDED PRINTED GLASS BOARD

摘要

A double-sided printed glass board is improved in heat resistance. A through hole (3) for electrically connecting the front and back sides of a double-sided printed glass board (1) is filled with a copper post (5) composed of a metal copper. The copper post (5) is formed by firstly closing one opening of the through hole (3) with copper by electrolytic plating and then continuing the copper-plating from the closed opening to the other opening of the through hole (3). Consequently, the front and back sides of the double- sided printed glass board (1) can be surely connected electrically, and the double-sided printed glass board (1) can have high heat resistance as a whole.
