PROCESS FOR PRODUCING THREE-DIMENSIONAL MICROWAVE TRANSMISSION CIRCUIT, AND THREE-DIMENSIONAL MICROWAVE TRANSMISSION CIRCUIT BOARD PRODUCED USING PROCESS

摘要

PROBLEM TO BE SOLVED: To produce a high performance three-dimensional microwave transmission circuit inexpensively.;SOLUTION: A metal plate material is employed as the material of electrode pattern on the three-dimensional microwave transmission circuit board, and machined into the electrode pattern by means of a press and then insert molded with molding resin thus constituting the three-dimensional microwave transmission circuit board. A production process of the three-dimensional microwave transmission circuit board employs a sequential feed production system in which a hoop material 121 is employed as the metal plate material, fed sequentially through presses 123 and 124, a former press 125 and an injection molding machine 126 to produce a three-dimensional microwave transmission circuit board material 110. Subsequently, it is cut from the hoop material 121 and metal plating is applied to the electrode pattern part. Since the three-dimensional microwave transmission circuit boards are mass produced, production efficiency is enhanced and man-hour can be reduced. Furthermore, the three-dimensional microwave transmission circuit board produced by this production process exhibits excellent conductivity and heat dissipation properties.;COPYRIGHT: (C)2006,JPO&NCIPI
