Problem: It has been desired to form a plurality of combinations of plating films continuously on a single transfer rail and to form a plating film having a high quality and a uniform thickness on the surfaces of a lead frame and leads. Solving means: The plating apparatus is provided below the single transfer rail with a plurality of plating tanks, in which plating solution baths are disposed. By moving the plating solution between the plating tanks and the plating solution baths, it is possible to select a plating film to be formed on a conductive member (21). As a result, it is possible to form combinations of plating films on the conductive member (21) continuously by the single transfer rail.

A method and apparatus for plating a substrate is provided, wherein fine pits formed in the substrate, such as fine channels for wiring, are filled with a copper, copper alloy, or other material with low electrical resistance. The method is performed on a wafer W having fine pits (10) to fill the fine pits with a metal (13) and includes performing a first plating process (11) by immersing the wafer in a first plating solution having a composition superior in throwing power; and performing a second plating process (12) by immersing the substrate in a second plating solution having a composition superior in leveling ability.

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von beschichteten Werkstücken aus Leichtmetall oder einer Leichtmetalllegierung umfassend die Schritte:
a) galvanische Abscheidung einer oder mehrerer Schichten, enthaltend mindestens ein Metall und/oder eine Metalllegierung ausgewählt aus der Gruppe Aluminium, Magnesium, Zink auf einem Substrat aus Leichtmetall oder einer Leichtmetalllegierung, und wobei das Substrat und die darauf aufgebrachte Schicht oder im Falle von mehreren Schichten zwei benachbarte Schichten nicht aus demselben Metall oder derselben Metalllegierung bestehen. b) Wärmebehandlung des beschichteten Substrates bei einer Temperatur zwischen 200 °C und 800 °C, so dass zumindest die Oberflächenschicht des Substrates und die in Schritt a) aufgebrachte Schicht/Schichten teilweise und/oder vollständig ineinander diffundieren.
sowie die durch das Verfahren hergestellten beschichteten Werkstücke.
摘要:
This invention relates to polyolefin alloys that are receptive to metal plating. These compositions also have enhanced properties and are easily processed into articles by various molding methods. The blends of the invention preferably include polyolefin homopolymers or copolymers, acrylonitrile-butadiene-styrene polymers, and a blend of at least one styrene monoolefin copolymer and at least one styrene diolefin copolymer. These blends have excellent platability and superior physical properties including enhanced rigidity, toughness, and dimensional stability.
摘要:
It is disclosed a method of depositing a seal coating and a seal system comprising at least two layers (3, 4) on the surface of an article (1). The upper or surface layer (4) has a higher chromium activity than a bottom layer (3) to reduce a diffusion of cobalt and the formation of cobalt oxide is reduced. The coating (2) of invention may be heat-treated to reduce or optimize the formation of cobalt oxide to sustain the wear property.
摘要:
An electromagnetic shielding copper foil superior in electromagnetic shielding ability, high in transmittance, and free from particle shedding comprising a copper foil on at least one surface of which a fine roughening particle layer of copper or an alloy is provided and having on the fine roughening particle layer a smoothening layer comprised of cobalt, nickel, indium, or an alloy of the same and an electromagnetic shield able to be suitably used for a PDP using the same. The fine roughening particle layer may also be a layer comprised of a fine particle roughening particle layer of copper on which a fine roughening particle layer of a copper alloy is stacked or may also be formed by a copper-cobalt-nickel alloy. The smoothening layer of the copper foil may be treated for stainproof or by a silane coupling agent to protect the surface of the copper foil.
