A circuit board device includes a flexible circuit board, a rigid circuit board bonded to at least a part of the flexible circuit board, and a metal plate bonded to at least one of the rigid circuit board and a portion of the flexible circuit board which is itself bonded to the rigid circuit board. Heat generated from components mounted on the rigid circuit board is dissipated through the metal plate to a frame, for example.

Circuit board device

The present invention relates to a method of manufacturing printed circuit boards. The manufacturing method of printed circuit boards under the present invention is to detach a release paper from a metal board on which holes are provided and to which the adhesive sheet and a release paper are attached. Thereafter, the metal board is glued to a resin board having at least one circuit layer and at least either of through holes or lead wire holes, by means of the adhesive sheet by pressing. An alternative manufacturing method of printed circuit boards under the present invention is to provide lead wire holes at the centers of resin filled holes in a metal board material, and to which an adhesive sheet and a release paper are attached. From the metal board material, a metal board is made by finishing its outer configuration. The release paper is detached from the metal board. Thereafter, the metal board is glued by pressing to a resin board having at least one circuit layer and at least either of through holes or lead wire holes, by means of the adhesive sheet.

Method of manufacturing printed circuit boards

The present invention relates to a method of manufacturing printed circuit boards. The method of manufacturing printed circuit boards under the present invention is to provide holes on a metal plate, to attach a prepreg to the metal plate, and to fill the prepreg into the holes by heat-pressing the metal plate to which the prepreg is attached. Thereafter, lead wire holes are provided at the centers of prepreg filled the holes, and a resin plate having at least one circuit layer and through holes is glued to the metal plate. Alternately, a resin plate having at least one circuit layer and lead wire holes, or a resin plate having at least one circuit layer, through holes and lead wire holes are glued to the metal plate on the side where the prepreg is attached.

The present invention relates to a printed circuit board and to a method of manufacturing the same. The printed circuit board has a reinforcing panel glued to the surface of a resin board. The resin board is provided with at least one circuit layer and through holes. The reinforcing panel contains a core in a plate form and is made of at least one curved board and a metal board glued at least to one side of the core. The reinforcing panel is provided with resin holes, the resin holes are filled with resin, and a lead wire hole is provided through the center of the filled-in resin. The center line of the through hole and that of the lead wire hole are almost identical. The manufacturing method provides a lead wire hole through the center of each resin filled hole in a reinforcing panel by a drilling device assisted by a hole position designating means. Thereafter, the reinforcing panel and a resin board having at least one circuit layer and through holes are glued together keeping the center line of each through hole and that of each corresponding lead wire hole almost identical.

Printed circuit board and method of manufacturing same

The present invention relates to a printed circuit board and to a method of manufacturing the same. The printed circuit board of the present invention consists of a metal board glued to a resin board which is provided with at least one circuit layer. The metal board is provided with holes which are filled with resin, and lead wire holes are provided at the centers of the resin filled holes. The resin board is provided with through holes. The center of the lead wire holes and the centers of the through holes are on identical lines. Further, the method of manufacturing a printed circuit board under the present invention is to provide resin holes on a metal board, filling the holes with resin, and providing lead wire holes at the centers of the resin filled holes. In this process, an identical hole position designating means is used for providing the resin holes and the lead wire holes. At least one circuit layer and through holes are to be provided on the resin board. Thereafter, the metal board and the resin board are glued together. In this process, the centers of the lead wire holes and the centers of the through holes are to be put on identical lines.
