STRUCTURE FOR INTERCONNECTION OF ELECTRIC PACKAGING STRUCTURE CIRCUIT CARD AND ITS MANUFACTURE

PURPOSE: To allow changing of contact interval on a card and that in a socket by placing an intermediate card comprising a contact along one end and a contact of different interval at one end, between a socket and one or more cards. CONSTITUTION: An intermediate card 1 is positioned between a standard card on which a part and a circuit are placed and an external wiring including a socket 3. The socket 3 is connected to a wiring board 4. On both surfaces 6 and 7 of one card 2 a part 5 is placed, while a printed wiring connects, arrayed at the end of the card 2. A conductor 8 from the part 5 passes a card through the contacts arrayed tightly along an end 9, while the array of contacts connect to the corresponding one on the intermediate card 1. On surfaces 12 and 13 of the intermediate card 1, a spatial margin is provided with a part and a circuit 11, so that an interval between contacts can be changed.
