    摘要： A printed-circuit board, especially a multilayer printed-circuit board, with projection electrodes integrated with via hole conductors. Each of the projection electrodes is highly adhesive to a corresponding one of the via hole conductors and has high strength, and thus the production method of the printed-circuit board is simplified. Projection electrodes formed of a cured conducting paste are formed in such a manner that the electrodes are integrated with the via hole conductors which consist of a conducting paste embedded into the via hole formed in an insulating resin substrate to form a printed board. The method for producing a printed-circuit board, includes making via holes that penetrate through a prepreg to whose surface a parting film is applied; filling the via hole with a conducting paste; compressing the prepreg under heat to cure the prepreg and the paste; and then peeling off the film. Thus, projection electrodes with a height corresponding the thickness of the film are formed in a manner such that the projecting electrodes are integrated with the via hole conductors.

    摘要： In BGA (Ball Grid Array), LGA (Land Grid Array) and the like, a resin layer is formed between an external connecting electrode of a chip carrier and a circuit wiring board. Consequently, the external connecting electrode can be prevented from cracking due to a difference between the coefficients of thermal expansion of the external connecting electrode and the circuit wiring board. Thus, the reliability in a thermal shock test can be enhanced. A connecting wiring which is conducted to an electrode of a semiconductor device is provided on a surface of an electrical insulating board, and the external connecting electrode for connection to a connecting electrode of the circuit wiring board is provided on a back face of the electrical insulating board. The external connecting electrode has a solder ball made of a conductor, and the resin layer formed on the side portion thereof.

    摘要： A method of making a multi-layered ceramic substrate which includes the steps of laminating a desired number of green sheets each being made of glass ceramics containing at least an organic binder and a solvent and each having a pattern of electrodes formed thereon by the use of an electroconductive paste, to thereby provide a green sheet laminate, The electrodes on opposite surfaces or an entire surface layer of the green sheet laminate are subsequently printed with a paste comprising an inorganic component added with at least an organic binder containing a Zn composition. On each surface of the laminate printed with the paste of the Zn composition, a green sheet made of an inorganic composition incapable of being sintered at a temperature of crystallization of the glass ceramics is then laminated thereby providing a laminate plate which is subsequently fired. After the firing, both of the inorganic composition incapable of firing sintered and the Zn composition are removed from the opposite surfaces of the laminate. The paste of the Zn composition may contains a main component selected from the group consisting of Zn, ZnO, Zn(OH).sub.2, ZnAl.sub.2 O.sub.4, and ZnCO.sub.3.
