Problems solved by technology

However, in the traditional method, it is easy to cause the golden finger to not be completely cut off due to the position shift of the wet film, or the cut-off place is uneven due to the peeling of the wet film

Embodiment Construction

[0044] The making and using of this embodiment are discussed in detail below, however, it should be appreciated that the present invention provides practical innovative concepts which can be embodied in a wide variety of specific contexts. The embodiments or examples described below are for illustration only, and do not limit the scope of the present invention.

[0045] Although terms such as “first” and “second” may be used in the present disclosure to describe various elements, regions, layers and / or sections, these terms should not limit such elements, regions, layers and / or sections. These terms are only used to distinguish one element, region, layer and / or section from another region, layer and / or section. Thus, a first element, region, layer or section discussed below could be termed a second element, region, layer or section without departing from the context of the present invention.

[0046] Furthermore, the terminology used herein is for the purpose of describing pa...

Abstract

A method of forming a golden finger structure includes forming at least one metal layer on a substrate, the at least one metal layer being adjacent to an edge of the substrate. The at least one metal layer is processed by laser to form a first groove in the at least one metal layer and expose the substrate, and the extension direction of the first groove is substantially parallel to the edge of the substrate and stretches across the processed at least one metal layer.

Description

[0001] This application is a divisional application of a Chinese invention patent application (application number: 201710897819.6, application date: September 28, 2017, invention name: method for forming a golden finger structure). technical field [0002] The invention relates to a method for manufacturing a gold finger structure, in particular to a method for manufacturing a disconnected gold finger. Background technique [0003] The edge connector or pin of the circuit board is also called a gold finger. Gold fingers can be configured in related devices such as computer graphics cards, memory, USB interfaces, etc., to be in contact with other substrates. Gold fingers must have good wear resistance and low contact resistance, which can meet the needs of multiple plugging and unplugging. Due to interface design requirements of some circuit boards, some gold fingers need to be cut off to form disconnected gold fingers. [0004] In the traditional truncation method, a wet f...
