  • Publication number: 20020147519
    Abstract: There is provided an experimental management apparatus and experimental management program for electroplating that can carry out an electroplating experiment more efficiently and can manage experimental data more efficiently. The electroplating experimental management apparatus has a computer body 1a, which includes a central processing unit 101, a program memory 102, and a data memory 103. The program memory 102 stores a predicted value calculation program 102a for working out a predicted value of an experimental result based upon a physical property data file 103a and an arithmetic expression data file 103b read out of the data memory 103; an experimental data management program 102b for obtaining experimental data; and a data analysis program 102c for working out experimental data at each point of time during experiment based upon analysis of the experimental data obtained by the experimental data management program 102b.

  • Patent number: 6153065
    Abstract: An internal stress testing device for high speed electroplating is disclosed. The testing device comprises: a tank to be filled with a plating solution; a metal plate for anode disposed within the tank; a metal rod for cathode disposed within the tank and rotatably held by a motor at a position opposite to the metal plate for anode; a metal plate for cathode in the shape of a thin plate mounted on the metal rod; and a DC power supply connected to the metal plate for anode and the metal rod for cathode.
