    摘要: A ground pattern (12) and power supply pattern (13) which are formed on the surface of a printed wiring board (10) are connected to a ground layer (21) and power supply layer (22) formed as the internal layers via bumps (24a, 24b). The ground pattern (12) need not be connected to the ground layer (21) by uniformly plating the inner side surface of a cavity (43), contributing to an increase in yield and a decrease in cost. When a power supply pattern (13) is to be connected to a power supply layer (22) using through holes, the power supply pattern (13) must be spaced apart from signal pins (14) detouring the region where the through holes are to be formed. However, the distance between the power supply pattern and the signal pins can.be reduced by using bumps. The distance between a semiconductor chip (41) and the signal pins (14) can be reduced to improve the electrical characteristics.

    摘要: There is provided a method for arranging conductive bumps at predetermined positions penetrated through an insulating layer during a press integration stage to ensure electrical and thermal conductivities between a wiring pattern and a conductive metal as well as electrical connections between the wiring patterns. More specifically, the sharp tip of the conductive bump is subjected to plastic deformation to form the interconnections between the wiring patterns or between the wiring pattern and the conductive metal. Also provided is a method of manufacturing a printed wiring board. A synthetic resin sheet is sandwiched by the surface on which conductive bumps are formed into a laminate. The laminate is heated until the resin component of the synthetic resin sheet being is in a plastic state or up to a temperature not lower than the grass transition temperature of that resin. At that time, the conductive bumps are forced against the synthetic resin sheet and are penetrated therethrough. This permits positive connections with a high accuracy without forming a through-hole.

    摘要: Small projections are arranged on a molding surface of at least one of an upper die half and a lower die half constituting a molding die, and a predetermined number of conductor circuits each including small projections are formed on the molding surface by electrically plating. A predetermined number of conductor circuits are formed on the molding surface of other die half in the same manner. Subsequently, the molding surfaces of both the die halves are brought in pressure contact with each other so that the electrically plated layers each including small projections on the molding surface are connected electrically. Thereafter, the hollow space between both the die halves is filled with a predetermined resin, whereby the conductor circuits are reversely secured to the resultant molded product to complete production of a three-dimensional wiring board. After electronic components are assembled on the three-dimensional wiring board, the resin is removed from the molded product by dissolving the resin. Consequently, a hollow three-dimensional wiring structure is formed. Thus, three-dimensional conductor circuits which are electrically connected to each other at predetermined positions are formed on the front and rear surfaces of molded product. Thus, the three-dimensional wiring board can be produced at a high efficiency without any necessity for complicated steps and actuation. An electronic circuit module produced by assembling electronic components on the three-dimensional wiring board assures that signals can be processed at a high speed.
