  • Patent number: 6544392
    Abstract: There is disclosed an improved apparatus for manufacturing printed circuit boards which solves the problem of immersion bath contaminants being plated-out onto electrically-conductive, circuit functional pads, (board-features) by introducing into the bath system a mechanism for attracting those contaminants to non-functional “micro-thieves” which are electrically-conductive, non-circuit-functional pads having substantially smaller dimensions than those of the smallest board-feature, thereby taking advantage of previously unknown immersion bath uncontrolled strike phenomena, whereby the contaminants are directed to the micro-thieves and away from the board-features. Application of the micro-thieves in the immersion bath environment also produces plated features, of both finer and larger geometries, having flatter surfaces and a more uniform plated thickness for all features on the printed circuit board (PCB), than previously obtained.

  • Patent number: 6099702
    Abstract: A plating cell has an inner plating bath container for performing electroplating on a work piece (e.g., a wafer) submerged in a solution contained by the inner plating bath container. A reclaim inlet funnels any solution overflowing the inner plating bath container back into a reservoir container to be circulated back into the inner plating bath container. A waste channel is also provided having an inlet at a different height than the inlet of the reclaim channel. After electroplating, the wafer is lifted to a position and spun. While spinning, the wafer is thoroughly rinse with, for example, ultra pure water. The spin rate and height of the wafer determine whether the water and solution are reclaimed through the reclaim channel or disposed through the waste channel.

  • Patent number: 6035925
    Abstract: A system of gating orifices for continuous pressure infiltration processes eliminates blow-out of the pressurized molten metal matrix material and friction damage to the infiltrated perform. The system includes three or more orifices along a vertical path of an upwardly moving perform which passes from vacuum or atmospheric pressure into a pressurized infiltrating bath of molten metal, then into a pressurized atmosphere in which the matrix fully solidifies, and from there to an atmospheric environment. The entering orifice, at the bottom of the pressurized bath, is elongated in the direction of the perform movement to provide a temperature gradient from above the matrix material melting temperature at the bath to below the solidification temperature farthest from the bath. The resulting liquid-mushy-solid sequence of the matrix material forms a solidification seal to prevent blow out of the pressurized molten metal.

  • Patent number: 5840121
    Abstract: A suction tip is moved between a seed-attracting position and a seed-releasing position when a rotary member is rotated by a drive source. The suction tip is moved upwardly and downwardly by an actuator attached to the rotary member. A gel-discharging mechanism disposed in alignment with the seed-releasing position includes a reciprocatable piston. When the piston moves front, a pressure is applied on gel, by which a hollow nozzle plunger opens a valve to allow the discharge of the gel. When the piston moves back, gel is supplemented. A portion of the gel discharged drops by its own weight, while the remainder forms a gel layer that closes the lower end of the hollow nozzle plunger. At the seed-releasing position, the suction tip is driven by the actuator to be lowered into the hollow portion to release the seed on the gel layer. Extremely small seeds can be reliably supplied on the gel layer at the lower end of the hollow portion.

  • Patent number: 5718768
    Abstract: Each suction tip on a support member is moved between a seed-sucking position and a seed-supplying position by a drive source (20) at a supplying unit, and a seed vessel is moved up and down by a drive source (40). A pressurizing plunger is moved front by a drive source (50) at a nozzle unit and pressurizes the gel inside a gel flow channel to move a cutting plunger up and open a valve to allow gel to be discharged. A part of the gel discharged drops, and the remainder forms a layer on which a seed is supplied. A counter of a controller counts the number of unsuccessful seed-sucking operations, and when the counted value reaches a predetermined number of times, the running of the apparatus is stopped. If a suction tip does not suck a seed at the seed-supplying position, instead of moving the pressurizing plunger front, another suction tip is moved to the positions.

  • Patent number: 5681392
    Abstract: A reservoir for dipping a non-cylindrical flexible belt into a coating fluid so that an electrophotographic layer can be deposited onto its outer surface during a manufacturing process includes a non-cylindrical tank with an inlet located at one end. A coating fluid enters the bottom of the tank and moves past a flow divider located inside or just above the inlet. This divides the entering fluid into two substantially equal portions, so that the level of coating fluid inside of the tank rises uniformly. The coating fluid passes first through a porous membrane, and then through a perforated plate, both of which will reduce the velocity of the coating fluid, to ensure that the fluid has laminar flow characteristics once it reaches the top of the reservoir. Finally, the coating fluid passes through an annular shaped flow director which ensures that the layer which is deposited onto the outer surface of the flexible belt has a uniform thickness.
