ABSTRACT:
A method of making connections to a microelectronic unit includes the steps of providing a connection component having a flexible dielectric top sheet, a plurality of terminals on the top sheet and a plurality of electrically conductive, elongated flexible leads connected to the terminals and extending side-by-side downwardly from the terminals away from the top sheet to bottom ends remote from the top sheet. The connection component is then engaged with a front surface of a microelectronic unit having an array of contacts thereon while subjecting the connection component and the microelectronic unit to heat and pressure so that bottom ends of the leads remote from the top sheet bond with the contacts on the microelectronic unit to form electrical connections therewith.
