Method and device for electrically connecting circuits to opposite surfaces of a printed circuit board

摘要

A device and method provide an easy and inexpensive electrical connection between circuits on both sides of a printed circuit board. A through-hole is formed in the board with conductive copper pads around the periphery of the hole on both sides of the circuit board. A malleable, conductive plug is inserted through the hole and then deformed. The plug has a length and diameter such that when deformed, it completely fills the hole and makes a solid electrical connection with the copper pads on both sides of the circuit board. Circuits on both sides of the circuit board may be electrically connected to each other through the copper pads and deformed plug.
