摘要： An electronic-component-mounted wiring substrate provides enhanced joining reliability when an electronic component is joined to terminal pads of the wiring substrate, has sufficient strength, and can prevent generation of warpage and formation of a short circuit, which would otherwise occur as a result of re-melting of solder. Solder completely covers an entire surface of each of the terminal pads provided on a laminated substrate such that they project therefrom, and also joins to terminals of the electronic component. Therefore, each of the terminal pads and the solder are joined together reliably, and sufficient electrical continuity is secured therebetween. That is, the reliability of a joint between the solder and each terminal pad is extremely high, and the reliability of joint between the terminal pads and the electronic component is extremely high.

摘要： A wiring board and a method for manufacturing the wiring board reinforced by means of a resin is provided. Embodiments of the wiring board allow for reliable attachment of a connection member, like a socket, to a terminal member. For example, a base of terminal pins is put on pin grid array (PGA) terminal pads, and a bonding material paste including solder and an electric insulation material made of a resin is placed on each of the PGA terminal pads. The bonding material paste is then heated to fuse the solder and soften the electric insulation material. Subsequently, the bonding material paste is cooled to solidify the solder and bond each of the bases to a corresponding PGA terminal pad and form an electric insulation surface layer on an exposed surface of each of solder junctions to which the respective bases are bonded.

摘要： A method for manufacturing a wiring board for mounting an electronic component, a wiring board for mounting an electronic component, and a method for manufacturing an electronic-component-mounted wiring board are provided. A bonding material paste, which can include solder and an electric insulation material made of a resin, can be placed on chip mount terminal pads and heated to fuse the solder and soften the electric insulation material. Subsequently, the solder is solidified to form solder bumps. Further, the electric insulation material is cured on a surface of each of the solder bumps and a surface of a multilayer board around each of the solder bumps to form an electric insulation surface layer. Accordingly, when a chip is mounted to such wiring boards, the electric insulation surface layer minimizes or eliminates the connection between adjacent solder bumps during re-fusing of the solder.
