  • Publication number: 20230193502
    Abstract: A wafer plating fixture for use in simultaneously electroplating a two substrates. The wafer plating fixture including: an electrically conductive carrier bus; a plurality of contact clips electrically coupled to the carrier bus and configured to hold the two substrates in place and electrically couple the two substrates to the carrier bus; and a non-conductive substrate backer to separate the two substrates coupled to the carrier bus. A method of electroplating a plurality of substrates. The method including: mounting two substrates to be plated onto a wafer plating fixture; mounting the wafer plating fixture on a continuous belt of plating system; dipping the wafer plating fixture with the two substrates held thereon into an electroplating bath; and applying a voltage to the two substrates via the wafer plating fixture.
    Type: Application

  • Patent number: 5138368
    Abstract: A hard copy such as a printed wiring board is fabricated by exposing to radiation a liquid crystal cell in which a desired pattern is written and directing the pattern-carrying radiation projected from the cell by transmission or reflection to a substrate which is coated with a material sensitive to the radiation and disposed alignedly at an exposure position by optical registration. The duration of the exposure is controlled for a given light intensity and for the type of the coating material. A pattern may be written in one cell substantially simultaneously as another cell is used for the projection imaging. After a produced pattern is compared with a reference pattern, corrections may be effected through a processor which controls the writing of a pattern in a cell.
