An assembly having a thermosetting layer pierced by a plurality of conductors is formed on a release sheet and subsequently sandwiched between an IC and a PWB or other supporting surface and subsequently cured. The release sheet is removed either before or during curing of the thermosetting material. Removal prior to curing may be accomplished via peeling. Removal during curing may be by destruction of the layer by the curing process. |
