Abstract:
A method of manufacturing a connecting structure of first and second printed wiring boards each having an electrode for conductively connecting to each other using a conductive film. A first printed wiring board with a resist film bonds to a second printed wiring board directly or using conductive film or bonding film. Both electrodes can be bonded using a conductive film and/or a bonding film. The resist film on one printed wiring board can be bonded to the electrode of another printed wiring board using a conductive film, or both resist films can be bonded using a conductive film.
Abstract:
A warp reducing member is bonded to an area on one surface of the substrate corresponding to other side of an electronic part for which the warp is to be reduced with respect to a substrate. An external size of the warp reducing member is substantially same as a size of each of a plurality of electronic parts or large enough to include multiple electronic parts. The warp reducing member is bonded to the substrate with a bonding material having a melting point lower than that of other bonding material that electrically connects the electronic parts to the substrate.
Abstract:
To provide a component mounting substrate and a component mounting structure which absorb stresses caused by impact or by the difference in the thermal extension coefficient between substrate and component, without increasing the required accuracy in soldering the substrate and the component together. The substrate, which is to be mounted with a component having one or more solder joints via which the component is connected to the substrate, has a depressed part thereof formed on its component side, on which one or more electrodes are provided to be closely joined with the solder joints. The depressed part is filled with a filling material with rigidity different from that of a material making up the substrate body, such that the filling material is flush or almost flush with the surface of the component side of the substrate.
Abstract:
A second member is superposed on a first member. A first recognition mark is described on the surface of the first member. A second recognition mark is described on the surface of the second members. The first recognition mark is fragmented along the edge of the second member when the second member is superposed on the first member. The second recognition mark ends at the edge of the second member. The second recognition mark cooperates with the first recognition mark for establishment of a predetermined geometric pattern. The relative positions of the first and second recognition marks can be adjusted based on an irregular or unshaped geometric pattern. The second member can thus reliably be superposed on the surface of the first member at the correct position.
