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.
