  • Method for manufacturing a double-sided printed circuit board
    Patent number: 9313900
    Abstract: Disclosed is a method for manufacturing a double-sided printed circuit board (PCB) having a circuit pattern by printing a conductive paste. According to the method of the present invention, a circuit pattern that is precise and highly conductive can be formed, and a reduction in raw materials and the simplification of processes are made possible. Also, due to the printing of the conductive paste, short-circuit can be prevented even when a conductive layer is bent or exposed to heat or physical impact.
    Type: Grant
