1. A separable electrical connector for electrically interconnecting an electrical device having two sides to a printed circuit board having two sides, comprising:
- a mechanical spring member for applying a compressive force;
an adapter board electrically connected to first side of the printed circuit board, the adapter board having electrical contacts on both sides;
a first layer of anisotropic conductive elastomer (ACE) between the one side of the electrical device and the adapter board;
a second layer of ACE between the adapter board and the first side of the printed circuit board, wherein this second layer of ACE accomplishes at least in part the electrical connection between the adapter board and the printed circuit board;
a stiffening plate on the other side of the printed circuit board; and
mechanical members interconnecting the spring member and the stiffening plate to apply a compressive force on both layers of ACE through the device, the adapter board and the printed circuit board.

Abstract
A separable electrical connector for electrically interconnecting an electrical device to a substrate. The connector includes an adapter board electrically connected to the substrate, the adapter board having electrical contacts on both sides, and a layer of ACE between the electrical device and the adapter board. A mechanical structure is used to apply a compressive force on the ACE through the adapter board and the electrical device.

12. A separable electrical connector for electrically interconnecting an electrical device to a substrate, comprising:
-
a package housing electrically connected to the substrate; a first layer of anisotropic conductive elastomer (ACE) between the package housing and the electrical device, for accomplishing a separable electrical connection between the package housing and the electrical device; a second layer of ACE between the package housing and the substrate, for accomplishing a separable electrical connection between the package housing and the substrate; and a mechanical structure that applies a compressive force on the second layer of ACE through the package housing; wherein the package housing defines edges, and wherein the mechanical structure comprises a clamping device that contacts the package housing around its edges but not the center, to leave the center open for separable electrical connection of the device to the package housing.
