  • Patent number: 5913985
    Abstract: A fixture for securing a circuit chip substrate having on one side solder connections during wet processing using a pulse jet delivery cleaning system for removing solder flux residue on the solder connections. The fixture comprises a frame of sufficient size to at least partially surround and contact the substrate on a first side and a lid cooperating with the frame to at least partially cover the substrate on a second side containing the solder connections. A resilient polymeric separator is disposed on the lid and faces the substrate for contacting the substrate second side containing the solder connections. There are also openings in the frame for permitting circulation of a cleaner to contact the second side of the substrate.

  • Patent number: 5863348
    Abstract: Method and apparatus for cleaning a workpiece such as a semiconductor element in which the element is placed on a chuck mounted on a rotation mechanism in which the rotation mechanism rotates around a first axis, and the element to be cleaned rotates around a second axis spaced from the first axis in a planetary manner. The cleaning process is programmed such that the element may be sprayed, immersed for a soak or pre-soak step, immersed while spinning, sprayed while spinning, and dried by heated gas, or any combination of these. The cleaning program is performed in a single chamber, which may be heated to a desired temperature.

  • Patent number: 5649676
    Abstract: A paper roll holder has a paper roll enclosure for rigid partially embedded mounting of the paper roll enclosure into an aperture in a vertical wall, the aperture in a vertical wall defining an upper edge and opposed lower edge in the wall, a releasable cover for releasable mating onto an exposed front face of the paper roll enclosure, the paper roll enclosure having an opposed pair of generally vertical side walls, a lower trough extending laterally between the sidewalls for receiving a paper roll therein, the lower trough having a generally horizontal front lip extending laterally between the side walls, a channel extending downwardly from an undersurface of the lower trough for releasable mating of the channel over the lower edge in the wall, an upper mounting flange extending generally parallel to the channel and extending generally perpendicularly between, and generally upwardly from, the side walls, a rear wall extending upwardly and forwardly from a laterally extending rear-most extremity of the trough
