Problems solved by technology

Traditional FPC fixtures are generally processed by CNC (Computerized Numerical Control, referred to as CNC), but nowadays FPC components are getting smaller and smaller, such as hundreds of microns in size, and the process difficulty is getting higher and higher. The processing accuracy of CNC processing has been difficult to meet the requirements , such as CNC machining is difficult to process a right-angle shape

Embodiment Construction

[0024] refer to Figure 1 to Figure 5 , the embodiments of the present invention will be described in detail below. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0025] refer to Figure 5 , the FPC jig manufacturing method of the embodiment of the present invention includes steps S1 to S3.

[0026] Step S1, cutting holes on the multi-layer metal plate by laser cutting.

[0027] processed into figure 1 The shape of the FPC jig shown is taken as an example, and the number of layers of the metal plate to be processed is selected according to the steps presented by the groove 40 of the FPC jig, and the specific number of layers needs to be determined according to specific needs.

[0028] For example, refer to figure 1 , the entire FPC fixture structure is divided into three layers of metal plates, which are the first layer of metal plate 1, the second layer of metal plate 2 ...

Abstract

The invention discloses an FPC jig manufacturing method. The method comprises the steps: forming holes in a multi-layer metal plate through laser cutting; removing a part of materials on the local surface, needing to be welded, of the metal plate so as to reduce the local thickness of the metal plate; and pressing the multiple layers of metal plates for welding through laser welding to obtain an FPC jig formed by welding the multiple layers of metal plates. The method can guarantee the precision of the FPC jig obtained through laser welding, and meets the requirements of machining precision ofan FPC.

Description

technical field [0001] The invention relates to the field of advanced manufacturing technology, in particular to a method for manufacturing an FPC jig. Background technique [0002] With the rapid development of electronic technology, the application fields of flexible printed circuit boards (Flexible Printed Circuit, FPC for short) are becoming more and more extensive. FPC has a flexible structure, small size, light weight, and can be bent, curled and folded, which greatly improves the freedom and flexibility of circuit design and mechanical structure design. [0003] The production and processing technology of FPC is relatively complicated, and the positioning of FPC in the processing process is particularly important. The use of FPC fixtures can improve labor productivity, reduce production costs, and can ensure product shape processing accuracy and processing reliability. [0004] The FPC components are pre-positioned in the groove of the FPC fixture, and the FPC is pla...
