    摘要: A process for making metallized plastic molding pellets comprising: first metallizing a laminated plastic sheet by sandwiching an electrically conductive metal foil in between two plastic films; secondly slicing the metallized laminated plastic sheet into a plurality of metallized plastic strips; thirdly wetting and binding the metallized plastic strips, which are radially arranged, with a thermoplastic resin matrix to form a metallized plastic bar by pultrusion processing; and finally cutting the pultruded metallized bar to obtain homogeneously metallized plastic pellets for making effective EMI shields.

    摘要: A conductor removal process is described, which is applied to a substrate that has thereon a plurality of patterns and a blanket conductor layer covering the patterns. An upper portion of the blanket conductor layer entirely over the patterns is oxidized to form a dielectric layer. A CMP step is performed to remove the dielectric layer and a portion of the remaining conductor layer in turn and thereby expose the patterns.

    摘要: A high gas pressure material capable of producing 50-300 psi gas pressure at forming temperature is placed in an enclosed area surrounding and sealing the blanks to be superplastically formed, without the use of argon gas. The blanks are formed under tensile stress by the internal pressure produced by the high gas pressure material. The method can be performed concurrently with diffusion bonding to obtain a metallic structure from a plurality of workpieces, and also can be used to manufacture perfectly spherical hollow bodies by a dieless method.

    摘要: The present invention provides a process for manufacturing an electromagnetic interference shielding metallic foil cladded plastic outer shell product. A first side of a superplastic alloy foil is coated with an adhesive and then the foil is placed foil in a first half mold to allow the foil to be initially superplastically formed. A second half mold attached to a nozzle of an injection machine is covered onto the first half mold, and the two half molds are closed to further deform superplastic alloy foil. Softened plastic is introduced from the injection machine to a mold cavity between the foil and the second half mold, such that the superplastic alloy foil covered on the first half mold is completely formed and the softened plastic adheres on the adhesive-coated side of the superplastic alloy foil to form an electromagnetic interference shielding metallic foil cladded plastic outer shell product. Two types of products can be obtained, that is, the superplastic alloy foil can be either the outer wall or inner wall. Moreover, the final metallic plastic product can not only have as intricate a shape as an ordinary plastic product, but also a shielding effectiveness as high as an ordinary metallic shield.
