Abstract
A low insertion force multichip in-line module comprises: a substantially rigid frame; a flex circuit having a plurality of integrated circuit chips disposed thereon, the flex circuit having contacts at least partially exposed along one edge of the frame; and, a compliant layer disposed between the exposed flex circuit and the rigid frame, whereby controlled deformation of the compliant layer enhances electrical continuity between the contacts and corresponding external electrical pins. Alternatively, a low insertion force multichip in-line module comprises: a substantially rigid frame; a flex circuit having a plurality of integrated circuit chips disposed thereon, the flex circuit having contacts at least partially exposed along one edge of the frame; a socket configured to matably engage the module; and, a compliant layer disposed between the exposed flex circuit and the rigid frame, whereby controlled deformation of the compliant layer enhances electrical continuity between the contacts and corresponding external electrical pins.
