    Abstract: A surface of an object to be plated is subjected to a treatment for palladium catalyst impartation to impart a palladium catalyst to the surface of an insulating part thereof. A palladium conductor layer is formed on the insulating part from a solution for palladium conductor layer formation which contains a palladium compound, an amine compound, and a reducing agent. On the palladium conductor layer is then directly formed a copper deposit by electroplating. Thus, the work is converted to a conductor with the solution for palladium conductor layer formation, which is neutral, without using an electroless copper plating solution which is highly alkaline. Consequently, the polyimide is prevented from being attacked and no adverse influence is exerted on adhesion. By adding an azole compound to the solution for palladium conductor layer formation, a palladium conductor layer is prevented from depositing on copper.

  • Publication number: 20090117398
    Abstract: A device, in particular a vehicle interior component, includes a base body (10) made of a first plastic material which is suitable for injection molding and for coating with chromium. The device furthermore includes at least one elastic partial body (16, 18) molded to the base body (10), which is made of a second plastic material which is suitable for injection molding, but not for coating with chromium. A method for manufacturing such a device with a base body (10) coated with chromium comprises the following steps: injection molding a base body (10) of the first plastic material; injection molding the partial body (16, 18) of the second plastic material to the base body (10); electroplating a chromium coating onto the base body (10), wherein the base body (10) passes through a chrome-plating bath together with the integrally molded partial body (16, 18).

  • Patent number: 7156973
    Abstract: This invention relates to increasing the electrocatalytic activity of conducting polymers so that the same may be useful for electro-oxidation of methanol which is important for fuel-cell technology. Conventional catalysts used for this process are based on Pt, Ru or Pd complexes which are incorporated in carbon/graphite based electrodes. However, these are not only expensive but difficult to fabricate in different shapes. Conducting polymer based electrodes have advantage of ease of fabrication but their activity has been found in the past to be not very high. The present invention provides a process for preparation of conducting polymer based electrodes which have very high catalytic activity (8 to 10 times higher) for electro-oxidation of methanol.

  • Patent number: 7005054
    Abstract: A method to make probes of a probe card includes providing a blocking plate on an electroplating tank. The blocking plate has a plurality of openings according to the layout of contact pads on a probe head. There are bumps on the contact pads of the probe head. Continuous electroplating process can be executed after bumps (contact pads) contact electroplating solution in the electroplating tank through the openings of the blocking plate. By continuously moving the probe head according to the desired shape of probes, probes were formed by electroplating. These probes can be made into different shapes with good uniformity in elasticity and heights to increase the quality of electrical contact during wafer probing. Moreover, the process lead time and fabrication cost are saved.
