Interposer/converter to allow single-sided contact to circuit modules

In combination, a substantially planar receptacle carrier and circuit card receptacle for adapting a semiconductor die-carrying circuit card bearing a double-sided edge connector for single-sided electrical contact, comprising.

• an elongated cavity structure with two contact rows, formed on the receptacle each contact row comprising a plurality of contacts arranged for mating with one of two opposing sides of said double-sided edge connector;
• a plurality of test pads on a surface of the circuit card receptacle electrically connected to said plurality of contacts in a one-to-one correspondence, said plurality test pads lying in substantially co-planar relationship;
• and
• a mechanism coupling said circuit card receptacle to said substantially planar receptacle carrier, permitting insertion and removal of said semiconductor die-carrying circuit card from said substantially planar receptacle carrier, while also allowing said semiconductor die-carrying circuit card to lie co-planar with said substantially planar receptacle carrier where said circuit card receptacle is mounted thereto.

A circuit card receptacle for adapting a semiconductor die-carrying circuit card bearing a double-sided edge connector for single-sided electrical contact, comprising:

• an elongated slot structure for receiving the double-sided edge connector of said semiconductor die-carrying circuit card;
• two groups of contacts mounted within said elongated slot structure, each contact group arranged for mating with one of two opposing sides of said double-sided edge connector;
• circuit traces carried by said circuit card receptacle electrically connecting said two groups of contacts to electrical test pads on a common surface of said circuit card receptacle;
• and
• a mechanism for mounting, said circuit card receptacle to a receptacle carrier extending substantially in a single plane.
