The system has a coating station receiving the wire and applying a polymer coating to the wire. A mask-forming station receives the polymer-coated wire and blows moist air over it to form air bubbles which result in holes in the polymer coating, thereby creating a mask. An etching station receives the wire, as coated with the polymer mask, from the mask-forming station and etches the wire through the holes in the polymer mask to form microcavities in the wire. A stripping station receives the wire from the etching station and removes the polymer mask from the wire, leaving the wire with microcavities. Processes of forming microcavities in a wire and, more generally, of making an etching mask having arrays of holes and conforming to substantially any surface, including an arbitrary curved surface, are provided.

In this aspect, the remaining air pressure zones can be set to 0 psi, which conserves fluid consumption.

  • Publication number: 20040123949
    Abstract: A unit for on-demand chemical etch. Stencil media is unwound from a stencil unwind hub and passed underneath the thermal print head and printed. The stencil media is a sandwich that is comprised of a porous material married to a pressure-sensitive adhesive coated carrier to supply stiffness and support to the mesh. After the stencil is printed, the carrier is peeled away and is rewound onto a carrier rewind hub, leaving only the printed stencil. This printed stencil is transported underneath the etching electrode, at which time, the electrode actuates downward, sandwiching the printed stencil between the electrode and the target object so that the chemical etching process may be performed. The spent stencil rewinds onto a stencil rewind hub. The stencil printing and etch functions can be provided in a handheld unit. The handheld unit is comprised of an actuating etching head, a print head, a ribbon support system and media support system.

  • Patent number: 6673156
    Abstract: A novel modular muffle etch injector assembly for use in a gas blanketed down-flow chemical vapor deposition apparatus of the type having a muffle and a modular gas injector assembly for introducing chemical vapors into a deposition chamber, the muffle being adapted for receiving and supporting the gas injector assembly, wherein deposition material residue collects on a lower surface of the muffle. The etch injector assembly of the present invention comprises an etch chamber having vertical sidewalls, a closed top end and an open bottom end, a supply mechanism for introducing a liquid etchant into the etch chamber, and a sealing device disposed along the open end of the etch chamber for providing a seal between the etch chamber and the lower surface of the muffle to confine the etchant to the etch chamber. The etch injector assembly preferably also includes an exhaust means for removing chemical vapors from the etch chamber.

  • Patent number: 6666984
    Abstract: An apparatus for forming a loop in a filament comprising a first wall having a first guide slot formed therein and a second wall having a second guide slot formed therein coplanar and parallel to the first guide slot. The first wall is opposite the second wall and each of the guide slots has opposing ends. A first gripper holds a filament at a first location. The first gripper is mounted from the first wall to the second wall at an end of each of the first guide slot and the second guide slot. The apparatus also includes a movable gripper to hold the filament at a second location. The movable gripper has a separation from the first gripper and is mounted from the first wall to the second wall adjacent to the other end of each of the first guide slot and the second guide slot for movement towards the first gripper to reduce the separation between them. This produces a loop of filament between the first gripper and the moveable gripper.

  • Publication number: 20030064158
    Abstract: A method and apparatus for improving the corrosion resistance of chrome plated materials. After the materials to be chrome plated are mechanically abrasively polished, but before they are reverse etched, they are power washed with a high-pressure liquid. A sprayer with nozzles directed inwardly towards the materials directs water onto the material at pressures in the range of 1000 or 2500 to 3000 psi. After the materials are chrome plated, they are heated above the melting point of a buffing compound, and then the heated materials with the buffing compound applied are buffed. An induction heater is used, before or after the buffing compound is applied. Computer controls, responsive to operator input of the cross-sectional size, composition and/or speed of movement of the chrome plated materials, to in turn regulate the power to an induction coil heater.
