Abstract
Abstract An adapter for coupling electrical signal to and from an integrated circuit device mounted on a circuit board has a frame composed of individual side sections with each side section having ribs formed therein for providing detented cantilever engagement of the side sections to the sides of the IC device. Electrically conductive elements fit in between the ribs and engage the leads on the IC. The electrically conductive elements are connected to conductive pads formed on a substrate that is secured with the frame. A securing means that includes pins are used for securing the side sections together.
