Conductive members formed of metallic wires constructed so that they extend linearly between a semiconductor element-mounting face and a circuit board-mounting face of a base member are integrally molded with the base member. For this purpose, a resin material for forming the base member is injected into a mold wherein the conductive members are linearly arranged beforehand.

A parts-packaging substrate comprising a metal wiring plate having a mask coated on its surface with several openings. This structure eliminates the need for a thick base formed of an insulating body and a resist layer required in prior art substrates. By bending a terminal of the metal wiring plate to form a connecting terminal, a connector used to connect to another substrate can be eliminated, reducing the cost of manufacture.

The invention provides a design evaluating method for assisting circuit-board-assembly, as well as an evaluation apparatus, for realizing high-quality, low-cost assembly by numerically evaluating any difference between targeted circuit design and actually performed circuit design, and further provides a recording medium having recorded thereon programs for executing the design evaluating method for assisting circuit-board-assembly. Concretely, an evaluation executing unit is provided and, after reading design evaluation programs from recording media on which the design evaluating programs have been recorded and prior to engineering-trial manufacture of a component-mounted-circuit board mounted components on the circuit board, at least one of a first design evaluation and a second design evaluation is executed. Accordingly, it is enabled to evaluate the appropriateness of a present circuit design before the engineering-trial manufacture, and thus high-quality, low-cost assembly can be realized.

An atmospheric oven containing an atmospheric gas kept at a predetermined purity accommodates a transport for transporting an object to be heated along a predetermined transporting path. A rectangular sectioned tubular body for preventing the gas from flowing outside the oven extends a certain length from an entrance of the oven and an exit of the oven and has a sectional area necessary for passing the object through the tubular body.

A film material for the manufacture of a film carrier has a lead pattern including an outer lead portion formed independent of the electrode arrangement of a semiconductor chip to be mounted on the film carrier, and an inner lead formation portion a part of which is selectively removable in accordance with the electrode arrangement of the semiconductor chip to be mounted thereon, the inner lead formation portion being contiguous and connected to respective leads of the outer lead portion. A method for manufacturing the film carrier includes the steps of forming a conductive layer of material on a film; forming the lead pattern by etching part of the layer formed on the film into an outer lead portion having a pattern independent of the electrode arrangement of each semiconductor chip to be mounted thereon, and by leaving another part of the layer as it is to form an inner lead formation portion having a pattern which is changeable according to the electrode arrangement of the semiconductor chip to be mounted thereon; and selectively removing part of the inner lead formation portion by laser processing in accordance with the electrode arrangement of the semiconductor chip to be mounted thereon.
摘要:
A method of manufacturing a semiconductor mounting board includes providing a base member and linear conductive members formed of metallic wires. The conductive members are constructed so that they extend linearly between a semiconductor element-mounting face and a circuit board-mounting face of a base member, and are integrally molded within the base member. For this purpose, a resin material for forming the base member is injected into a mold wherein the conductive members are linearly arranged beforehand.

An electrode terminal (5) provided on a surface of a semiconductor chip (4) has a square shape in plane view. Further, the projecting apex portion (8a) of a bump (8) provided on the electrode terminal (5) orients to a corner portion (5a) of the electrode terminal (5). Hereupon, a gold ball (2a) formed by melting the lower end portion of a gold wire (2) supplied through a capillary (1) is joined to the electrode terminal (5), and then the capillary (1) is moved in the direction of a diagonal line of the square electrode (5). Thus, the main portion of the gold wire (2) is separated from the gold ball (2a) so that the bump (8) is formed.
