Abstract
A separable electrical connector for electrically interconnecting an electrical device to a substrate. In one embodiment, 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. In another embodiment, the connector includes a translator board having electrical contacts on both sides and electrical circuits within to expand the footprint of the fine pitch electrical device to the coarser pitch of the substrate. The connector further includes a layer of ACE between the translator board and the substrate. In a further embodiment, the separable electrical conductor includes a layer of ACE coupled to a frame and an adaptor board that includes a channel sized and shaped to engage the frame, thereby reducing the profile of the connector. In another embodiment, the layer of ACE is coupled directly to the adaptor board, without the use of the frame, by means of an adhesive contained in the channel.
