A main object of the present invention is to provide a substrate for suspension which is produced at low costs and can sufficiently attain the prevention of damage by electrostatic discharge and restraint of noises. To attain the object, the present invention provides a substrate for suspension, comprising: a metallic substrate, an insulating layer formed on the metallic formed in substrate and having an opening from which the metallic substrate is exposed, a grounding-wiring layer formed on the insulating layer and arranged near the opening, and a ground terminal formed in the opening and contacting the metallic substrate and the grounding-wiring layer, characterized in that the ground terminal is made of a metal having a melting point of 450&#xb0; C. or lower.

Substrate for suspension, and production process thereof

A separator for flat-type polymer electrolyte fuel cells comprises a fuel-feed-side separator and an oxygen-feed-side separator, each comprising a collector portion in which n unit conductive substrates (n is an integer of 2 or more), each having a plurality of through-holes, are arrayed in flat configuration via gaps, and a pair of insulating frames which have n openings in alignment with an array position of the unit conductive substrates and are integrated in such a way as to hold the collector portion between them. The back-to-back (n&#x2212;1) unit conductive substrates of the n unit conductive substrates in one of both separators, as counted from the end of its array direction, and the 2to nunit conductive substrates of the n unit conductive substrates in another separator, as counted from the end of its array direction are successively joined together by means of (n&#x2212;1) connecting hinges.

The object of the invention is to provide a separator for fuel cells which is of improved strength and corrosion resistance and facilitates the assembling of unit cells. The separator comprises an electrically conductive resin layer formed by electrodeposition in such a way as to cover a metal substrate and a gasket component. The resin layer contains an electrically conductive material. The separator of the invention has thus an enhanced corrosion resistance, makes some considerable improvements in the assembling work efficiency of unit cells, and makes sure higher strength because of the use of the metal substrate.

A fabricating method of a wiring board provided with passive elements is disclosed. The fabricating method includes coating one or both of resistive paste and dielectric paste on at least any one of first surfaces of a first metal foil and a second metal foil each of which has a first surface and a second surface; arranging an insulating board having thermo-plasticity and thermo-setting properties so as to face the first surface of the first metal foil, and arranging the first surface side of the second metal foil so as to face a surface different from a surface to which the first metal foil faces of the insulating board; forming a double-sided wiring board by stacking, pressurizing and heating the arranged first metal foil, insulating board, and second metal foil, and thereby integrating these; and patterning the first metal foil and/or the second metal foil.
