  • Conductive paste
    Patent number: 4435611
    Abstract: A novel conductive paste is disclosed which is suitable for use to connect circuit patterns of a printed circuit board.The conductive paste comprises a melt of gallium and a metal element which forms an eutectic mixture with gallium, and metal powder which alloys with gallium uniformly dispersed in the melt. The content of the metal element and the metal powder are selected to control a solid content in the paste at a predetermined working temperature.

  • Nickel electroplating bath for satin finish and method
    Patent number: 4058439
    Abstract: A nickel electroplating emulsion bath for obtaining a satin-finish which comprises an aqueous acidic continuous phase nickel salt solution, an alcohol soluble polyamide resin dispersed therein and a polishing agent and the method for using the bath. The polyamide resin is a member selected from the group consisting of a copolymer of dimer acid and an aliphatic amine, a copolymerized nylon and a modified nylon. The electroplating bath preferably also contains a cationic surface active agent selected from the group consisting of an aliphatic and/or aromatic quaternary ammonium salt and an aliphatic and/or aromatic fluorosulfonylamine quaternary ammonium salt. The use of the electroplating bath provides a means for obtaining a uniform satin-finish nickel plate surface on the material plated.

  • Coated plating rack
    Patent number: 3939056
    Abstract: A rack for supporting electrically non-conductive articles during the successive chemical or electroless plating and electroplating of such articles has its metal frame covered with a plastic resin coating in which there is dispersed one or more organosulphur compounds so that plating material will not adhere to the rack during the chemical or electroless plating of articles supported thereby nor during the subsequent further electroplating of such articles.
