Abstract

Abstract Processes for preparing same for demateably interconnecting arrays of contact pads. The connector has a preformed sheet-form member provided with a series of apertures through each of which an electrically conductive plated metal deposit extends. An integral end of the deposits protrudes outwardly beyond a surface of the sheet-form member, forming contact surfaces for demateably engaging the pads.
