PURPOSE:To enable to exchange and to connect the LSI's simply by a method wherein a multilayered printed wiring board and a flat plate type circuit substrate mounting the LSI's of the plural number are connected by connectors provided with flat cables. CONSTITUTION:The input/output signal pins 5 of the multilayerly printed wiring board 2 and the contact springs 42 of the connectors 4 provided with the flat cables are connected by inserting the connectors. Then, the connecting terminals 12 on the flat plate type circuit substrate 8 mounting the LSI's of the plural number and the contact springs 41 of the connectors 4 provided with the flat cables are connected by inserting the connectors. Moreover a connector base 15 is fixed on the multilayerly printed wiring board 2 by mounting screws 61 and mounting nuts 61', the connectors 4-4''' provided with the flat cables are fixed to the fixing parts 16 of the connector base 15 thereof, and the connectors 4-4''' provided with the flat cables to connect electrically between the multilayerly printed wiring board 2 and the flat plate type circuit substrate 8 mounting the LSI's of the plural number are equipped at the four places of the circumference of the flat plate type circuit substrate 8. Accordingly the flat plate type circuit substrate 8 and the connectors 4-4''' provided with the flat cables can be exchanged simply. |
