Abstract
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.
Claims15
A connection electrode connecting device, comprising:
- a plurality of opposing electrodes provided on a substrate surface;
- connection electrodes which are formed on protrusions of approximately hemispherical shape on a flexible substrate positioned so as to face each of the opposing electrodes;
- conical tip portions of an inelastic material which contact the rear of the protrusions on the flexible substrate and apply a pressing force to a rear of the protrusions;
- and
- cylindrical base portions formed of an elastic material which support the tip portions.
A connection electrode connecting device, comprising:
- a flexible substrate having at least one protrusion from a first surface;
- a connection electrode mounted over and conforming to each said protrusion;
- and
- a backup member opposing a second surface of said flexible substrate and associated with each said protrusion, wherein said backup member has a tip portion formed of a non-elastic material and a base portion formed of an elastic material.
