  • Publication number: 20060113669
    Abstract: A multi-layer structure including a base insulating layer and a thin metal film layer (seed layer) is prepared. A plating resist layer is formed to have a prescribed pattern on the upper surface of the thin metal film layer. A metal plating layer is formed on the thin metal film layer exposed by electroplating. Then, the plating resist layer is removed, and the thin metal film layer in the region having the plating resist layer is removed. In this way, a conductive pattern including the thin metal film layer and the metal plating layer is formed. The upper surface of the base insulating layer in the region without the conductive pattern is subjected to roughening treatment. A cover insulating layer is formed on the upper surfaces of the base insulating layer and the conductive pattern. In this way, a printed circuit board is completed.

  • Publication number: 20060042823
    Abstract: A wired circuit board which even when a conductive pattern is formed in the form of fine pitch can provide improved adhesion between the conductive pattern and an insulating layer to prevent a plating solution from remaining between a metal plating layer and the insulating layer, so as to prevent ionic impurities in the plating solution from remaining as residual or ionic contamination, whereby even when electric current flows through the circuit under a high temperature and high humidity environment over a long term, a short circuit from ionic migration can be prevented to suppress insulating failure. Lower end portions of terminal portions 5 formed on an insulating base layer 2 and lower end portions of side surfaces and metal plating layers 6 covering over the terminal portions 5 are embedded in the insulating base layer 2 in a flexible wired circuit board 1 at one longitudinal end portion thereof exposed from an insulating cover layer 4.

  • Patent number: 6783887
    Abstract: In the method for manufacturing the battery module according to this invention, after a pair of welding upper/lower electrodes 21, 22 or 23, 24 are arranged in contact on the cases 16, 16 of adjacent unit cells 10a, 10b of a plurality of unit cells aligned in a line, a welding current is passed between the pair of welding upper electrodes 21, 23 from a welding power source while both ends of the unit cells 10a, 10b, 10c are pressurized by pressurizing members 31, 32 under a prescribed pressure. Thus, Joule heat is generated at the contact portion between the bottom of the outer case 16 of the unit cell 10a and the positive polarity terminal 18 of the unit cell 10b so that the contact portion melts. Accordingly, the bottom of the outer case 16 of the unit cell 10a and the positive polarity terminal 18 of the unit cell 10b are welded to each other at the contact portion.

  • Publication number: 20030219608
    Abstract: A metal transfer sheet which is so low in peel-strength as to be transferred to an object to be transferred with ease and reliability; a producing method thereof; and a ceramic condenser producing method for producing a reliable, compact, thin-layer ceramic condenser with improved production efficiency by transferring a metal layer to the ceramic condenser by using the metal transfer sheet. After a first metal layer is formed on a carrier film in a sputtering or an electrolytic plating method, the member thus formed is dipped in plating solution and voltage is applied in such a way that the first metal layer side is anode, to form a passive film. Sequentially, with the polarity reversed, voltage is applied in such a way that the passive film side is cathode, to form the second metal layer. After this manner, a metal transfer sheet in which the first metal layer and the second metal layer are laminated through the passive film interposed therebetween is obtained.
