Abstract
A high density printed circuit board carrying integrated circuits or the like is provided with two parallel rows of terminals along one edge on both sides of the board. The terminals in the outer row of terminals closest to the edge of the board are connected to printed circuits on inner layers of the multiple layer printed circuit board by plated-through holes or other suitable techniques; and the printed circuits on the outer layer or layers are connected to the inner row of terminals spaced just inside the outer row of terminals. A circuit board connector is provided with spring contacts which are electrically insulated from one another but which are designed to engage the multiple layer printed circuit board at the position of the first and second rows of terminals. The spring contacts engaging the inner row of terminals on the circuit board are longer in length than those engaging the outer row of terminals, and are thus easily deflected so that the P.C. board may be inserted or removed from the connector without excessive force.
