    Abstract: PURPOSE:To obtain a gold plating bath usable at ordinary temp. for a long period by adding triethanolamine to a gold plating bath contg. citric acid, an alkali metallic citrate and an alkali metallic gold cyanide as the principal components to regenerate the gold plating bath. CONSTITUTION:A soldered substrate having through holes is plated with gold in a gold plating bath contg. citric acid, potassium citrate and potassium gold cyanide as the principal components, a brightener and other additives. When the plating bath is prepd. of deteriorated after use, triethanolamine is added to the plating bath by about 1-20g per 1l bath. Triethanolamine produces a more significant effect when it is added to the deteriorated plating bath.

    Abstract: PURPOSE: To prevent sticking of the suspended matter on the surface layer part of an eletrolyte on the surface of a printed circuit board and to form a plating layer having a uniform thickness by dipping said board in tap water prior to electroplating on the surface thereof to remove the fine deposit on the surface then dipping the board into the electrolyte.
    CONSTITUTION: The fat, oil and oxide sticking on the copper foil 31 on the surface of a printed circuit board 3 are removed by an alkali or acid and thereafter the board is dipped in a washing tank 9 where the fine deposit on the surface of the foil 31 is washed away by the shower 13 of fresh water 11 pressurized with a pump 10. The board 3 having the surface wet with the water 11 is suspended from a suspending machine 6, and is lowered onto an electrolyte 2. The sticking of the fine suspended matter 7 on the surface 21 of the electrolyte on the copper foil layer 31 on the surface of the board 3 is obviated by the presence of the fresh water layer 11 and therefore the formation of the nonuniform plating layer owing to the sticking of the fine suspended matter on the surface of the board 3 is prevented.

    Abstract: 本発明は、機能性材料を含有するライン状液体から複数の機能性細線を形成する際、機能性細線の配置間隔を広くしても該機能性細線が視認されにくい機能性細線パターンの形成方法及び機能性細線パターンの提供を課題とし、その課題は、基材1上に、機能性材料を含有するライン状液体を互いに重ならないように複数並列するように付与し、次いで、ライン状液体の乾燥に伴い、ライン状液体の周縁部にそれぞれ機能性材料を選択的に堆積させることにより、2本一組の互いに平行な線分31を有する細線3をそれぞれ形成し、次いで、細線3の一部をそれぞれ除去し、細線3の残存部位によって機能性細線をそれぞれ形成する方法であって、機能性細線の配置間隔を300μm以上750μm未満としたとき、機能性細線の線幅を2μm以上7μm以下とし、配置間隔を750μm以上2.5mm以下としたとき、線幅を2μm以上5μm以下とすることで解決される。
