<p>PURPOSE:To improve the life and reliability of a contact part between an anisotropic conductive connecting means and a connecting terminal part of a printed circuit board in a card-like electronic device used as an external memory of an electronic equipment by electrically and mechanically connecting the contact part by hard soldering or the like. CONSTITUTION:An anisotropic conductive connecting means 5 for connecting an external terminal with a terminal part 10 of a printed circuit, board 2 has a conductor of metallic thin wires 8-8''. The metallic thin wires 8-8'' are embedded in an elastic insulating material 7. One ends of the thin wires are connected to the terminal part 10 of the printed wiring on the circuit board 2 by hard solders 9-9''. The terminal part 10 is connected to a printed wiring 11. An elastic member for sealing purpose may be omitted. Accordingly, the electric resistance and contact pressure can be reduced, and the life and reliability of the device are improved. Moreover, precious metals become unnecessary.</p> |
