A manufacturing method of an interposed substrate is provided. A metal-stacked layer comprising a first metal layer, an etching stop layer and a second metal layer is formed. A patterned conductor layer is formed on the first metal layer, wherein the patterned conductor layer exposes a portion of the first metal layer. A plurality of conductive pillars is formed on the patterned conductor layer, wherein the conductive pillars are separated from each other and stacked on a portion of the patterned conductor layer. An insulating material layer is formed on the metal-stacked layer, wherein the insulating material layer covers the portion of the first metal layer and encapsulates the conductive pillars and the other portion of the patterned conductor layer. The metal-stacked layer is removed to expose a lower surface opposite to an upper surface of the insulating material layer and a bottom surface of the patterned conductor layer.

A method for manufacturing a product from a flexibly rolled strip material includes the steps of: providing a strip material made from sheet steel; flexibly rolling the strip material such that a variable thickness is produced along the length of the strip material; electrolytically coating the strip material with a metallic coating material containing at least 93% of zinc by mass after the flexible rolling; heat treating at temperatures above 350° C. and below a solidus line of the coating material after the electrolytic coating; working a blank from the flexibly rolled strip material; and hot forming the blank.

The present disclosure involves a method for partial gold plating of a metal packaging housing and a packaging housing thereof. The packaging housing may include a base. The base may be provided with at least one lead hole. A housing lead may be interspersed in the lead hole. The lead hole may be also provided with an insulator surrounding the housing lead. The method may include operations such as nickel plating, oxidation, gold plating, reduction, etc.

Certain embodiments are described herein that are directed to articles comprising textured coatings that can enhance adhesion of a surface coating. In some examples, the textured coating comprises at least one metal or metallic compound present in a plurality of individual microstructures which can be positioned in different planes in different heights with respect to a reference zero point in the textured coating. In some configurations, a surface coating comprising a repellent material can be disposed onto the textured coating and may infuse into or grip the textured coating to enhance adhesion of the surface coating.

The subject matter of the invention relates to a method for producing an electrical connection part, in which an electrical conductor (2) is provided, the electrical conductor (2) is electroplated and a contact area (4)of the conductor (2) is exposed by removing the electroplating (6). A method is to be specified with the subject matter of the invention which enables an electroplating (6) provided on the connection part (22) to be removed in a way which is particularly cost-effective and reliable. This is achieved according to the subject matter of the invention by removing the electroplating (6) in the contact area (4) using a beaming source (8).
