Connection electrode connecting device

摘要

Connection electrodes provided on the surface of a base film of a flexible substrate are pressed into contact with opposing electrodes provided on the surface of a facing rigid substrate. Backup members press the base film from the rear of each connection electrode. Each of the backup members has a cylindrical base portion and a conical tip portion which contacts a concave surface of the base film at the rear of each connection electrode. The conical tip portions are formed of an inelastic resin which does not deform elastically even if subjected to pressure and the cylindrical base portions are formed of an elastic resin which has a springiness. The cylindrical base portions apply a spring force to the base film when compressed so that the connection electrodes and the opposing electrodes form good electrical connections.
