  • Patent number: 6437251
    Abstract: This invention provides a specially-shaped, double-face flexible printed wiring board having a small pitch at a high production yield. Metal wirings 22 and 32 formed on a base film 21, 31 of two elemental pieces 20 and 30 of a flexible printed wiring board are arranged in such a manner as to face each other while sandwiching a bonding film 16 not containing conductive particles between them, and are heat-pressed to each other. The adhesive resin film 16 so softened is pushed aside from the metal wirings 22 and 32 and the low melting point metal coating films 23 and 33 formed on the surface of the metal wirings 22 and 32 come into direct contact with each other and are fused. In this instance, the softened adhesive resin film 16 is charged between the metal wirings 22 and 32. Therefore, the molten low melting point metal does not scatter. The base films 21 and 31 are bonded by the adhesive resin film 16.

  • Patent number: 6395993
    Abstract: The present invention aims to manufacture a reliable multilayer flexible wiring board at high yield. Flexible wiring board 10 used for multilayer flexible wiring board 40 of the present invention has metal coating 14 on the surface of metal wiring film 19, and metal coating 14 is exposed within the contact region. A wall member rising above the surface of metal coating 14 is provided around the exposed metal coating 14. The wall member is formed of wall face 23 of opening 17 in resin film 15 at the top of metal wiring film 19, for example. When bump 34 having low-melting metal coating 36 is contacted with metal coating 14 in said contact region and heated above the melting point of the solder metal under pressure, low-melting metal coating 36 melts. The molten low-melting metal is stopped by wall face 23 from overflowing outside the contact region so that any bridge cannot be formed by the solder metal between metal wiring film 19.
