Title: Apparatus to electrically couple a conductive layer to a conductive element and method therefor, and apparatus to electrically couple conductive layers of a circuit board and method therefor
Inventor: BURTON EDWARD ALLYN
IPC: H05K1/02
Filed: 1999-07-20
Granted: 2002-07-21
Abstract: An improvement is presented for connecting conductive components of a built-up circuit board.
