A system and apparatus that removes and collects non-functional wire assemblies from dicorotron units is described. It has a removal tool with flexible levers mounted on the top of a storage box. The removal tool has an open top and bottom, the open bottom is aligned with an opening in the top of the box to permit a dislodged anchor and wire assembly to fall therethrough.

Dicorotron wire assembly removal and storage tool

Electrostatic printing processes utilize corona-charging units. When those units wear out or become faulty, they need to be replaced. This embodiment provides a tool that can be used to remove a faulty electrode wire assembly from the unit. This same tool when loaded with a new wire assembly can insert a new wire assembly into the emptied corona charging unit, sometimes referred to as a dicorotron unit. The tool, therefore, is used both to remove or insert a wire assembly from or into a dicorotron unit.

A plasma sprayed TiOcoating is used to remove effluents produced during an electrical charging step using a corona charging device. The plasma spray allows for the application of TiOceramic to an aluminum dicorotron housing. Plasma spray also increases the electrical conductivity of the TiO(which is necessary for the dicorotron operation). Plasma sprayed coatings are also porous which aids in the capture and reduction of effluents.

A dicorotron unit and a wire assembly of a dicorotron unit where a wire electrode is strung between two insulator anchors. The anchors are held in place by flexible grippers. The grippers have flexible tabs that snap into the dicorotron housing and allow the grippers to remain in this housing when the wire assembly is removed from the dicorotron unit.

A method of forming a fiducial in a stencil for screen printing and the stencil so formed is described. A target fiducial thru-hole of a first size is formed in the stencil, the surface of the stencil in an area around and larger than the size of the target thru-hole is electrochemically etched, and the target fiducial thru-hole is filled with a filling material. The target fiducial thru-hole, included as part of the stencil pattern, is used as a target to which the fiducial mask, used in the electrochemical etching, can be aligned to. The target fiducial thru-hole may be made smaller than previously feasible because the fiducial is electrochemically etched, which means that it cannot fall out of the stencil. The filling in the target fiducial thru-hole is less likely to fail since it has a drastically decreased surface area to wall thickness area ratio compared to conventionally formed fiducials.
