摘要:
There is disclosed an apparatus for use in an electroetching or electrodeposition process in which material is etched from or deposited onto the surface of an electrically conductive component. The apparatus comprises a support for supporting the component within a tank containing an electrolytic solution; and a first-polarity electrode arranged to be located within the tank and immersed in the electrolytic solution and shaped to surround at least a part of the component in a contactless manner. In use, an electric field produced by the first-polarity electrode results in an electric variance between at least a part of the component and a second-polarity electrode having a polarity opposite to that of the first-polarity electrode. An electroetching and an electrodeposition process are also disclosed.

摘要:
The present invention provides an agitator (1) for agitating a liquid (10, e.g. an electrolyte solution) containing particles (e.g. abrasive particles) within a tank (9). The agitator comprises an agitator body having an upper surface (3) and a lower surface (4) with at least one aperture (5, 5') extending through the agitator body. There is a one-way valve (7, 7') for allowing liquid flow through at least one aperture from the upper surface to the lower surface and for blocking liquid flow through at least one aperture from the lower surface to the upper surface.
摘要:
A charge transfer mechanism is used to locally deposit or remove material for a small structure. A local electrochemical cell is created without having to immerse the entire work piece in a bath. The charge transfer mechanism can be used together with a charged particle beam or laser system to modify small structures, such as integrated circuits or micro-electromechanical system. The charge transfer process can be performed in air or, in some embodiments, in a vacuum chamber.

Nano-sized particles of carbon black and various metal ions are mixed to form substantially homogenous solutions or dispersions. The nano-sized particles of carbon black and metal ions are electroplated on various types of substrates as composites of one or more metals and substantially uniformly dispersed nano-sized particles of carbon black within the metals.
摘要:
A conductor (2) of a plug, socket or connector is provided. The substrate of the conductor (2) is steel and the conductor is obtained by plating a coating of Ni on the substrate, and then plating Cu on the outer surface of the substrate by electrolyzing or electrodepositing, using the substrate as the cathode. Alternatively, the substrate of the conductor (2) is stainless steel, and the conductor (2) is obtained by cladding Cu directly on the columnar stainless steel substrate.

The invention provides a method for electrolytically increasing the thickness of an electrically conductive pattern on a dielectric substrate, comprising the steps of
immersing the substrate with the pattern present thereon in an electrolytic bath, electrically contacting in the electrolytic bath a negatively charged electrode with the pattern during immersion of the substrate, and effecting contacting movement in the electrolytic bath of the electrode and the pattern with respect to each other during immersion of the substrate.
The invention furthermore provides a device for electrolytically increasing the thickness of an electrically conductive pattern on a dielectric substrate.
摘要:
Bei konventionellen Galvanisierverfahren wird das Substrat, z.B. eine mit einem halbleitenden Material beschichtete Glasplatte (1), in einem bewegten Metallsalzbad (2) metallisiert, z.B. vernickelt, wobei die Glasplatte als Kathode und eine Metallelektrode (3) als Anode geschaltet ist. Die Glasplatte wird langsam an der Metallanode vorbeigezogen Das Problem liegt darin, schwierig zu galvanisierende Substratmaterialien, wie z.B. ITO (Indium-Tin Oxide), mit einer genügend haftfesten Metallschicht (z.B. Nickel) zu versehen. Diese Problem wird dadurch gelöst, daß in das für die Metallisierung verwendete, Tenside enthaltende Nickelbad (5) von unten soviel Luft eingeblasen wird, daß sich an der Badoberfläche eine beständige Schaumschicht (8) bildet. In diese Schaumschicht taucht die Nickelanode (6) ein, an der die zu vernickelnde ITO-Glasplatte (1) langsam vorbeigezogen wird. Damit wird eine sehr haftfeste Nickelschicht gleichmäßiger Dicke erreicht.
