AI Technical Summary

Problems solved by technology

However, traditional CNC machining and die stamping are difficult to meet the accuracy requirements, and mechanical wear will lead to a decrease in accuracy, resulting in unstable accuracy
In addition, the lines of the gold finger are densely distributed, and a slight deviation in position can cause the gold finger to be misplaced in the connection, which will lead to abnormal signal communication of the gold finger, and thus lead to a low yield rate

Embodiment Construction

[0029] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0030] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as...

Abstract

The invention discloses a method for machining a golden finger. The golden finger is manufactured in the mode that CCD locating and laser cutting are combined. The laser is stable in spots and adjustable in size. Therefore, the size of spots of the laser can be adjusted according to requirements to meet the requirement for accuracy of the golden finger, loss, caused by continuous conducting of the machining process, of the laser can not be generated, the size of the spots can not be changed, and the accuracy of the golden finger can be stable. Besides, through CCD locating, a laser device can be accurately controlled to cut according to graphs of the golden finger of a machining file, a laser cutting route is prevented from offsetting, and therefore the yield of golden finger products is improved.

Description

technical field [0001] The invention relates to laser cutting technology, in particular to a golden finger processing method. Background technique [0002] The so-called gold finger refers to a row of square pads arranged at equal intervals. Because the surface is conductive by copper plating, tin plating, gold plating or nickel plating, it is shaped like a finger, so it is called "gold finger" and is mostly used in computer memory. , control board, LCD display driver and other functional connection components, etc. [0003] The gold finger substrate used as a memory stick is mostly made of thick resin material, which is formed by etching finger circuits or multi-layer circuits on the surface through pattern transfer. The processing accuracy of the general mechanical CNC milling machine can meet the requirement of plus or minus 0.1 mm. With the function and structure of commercial and industrial products have been greatly improved, the appearance volume is required to be sm...
