Embodiment 1

[0028] A high-efficiency and low-cost wire hole process, the high-efficiency and low-cost wire hole technology specifically includes the following steps:

[0029] S1. Pad production: make pads on the FPC soft board;

[0030] S2. Pad area positioning: according to the position of the pad area on the FPC soft board, measure and record the relative position between the pad area on the FPC soft board and the positioning hole on the FPC soft board;

[0031] S3. Transformation of the lower mold of the outer contour of the FPC soft board: set the positioning holes on the FPC soft board on the positioning columns of the lower mold of the outer contour of the FPC soft board, and use a marker pen according to the relative position of the pad area obtained in S2 The information identifies the position of the area directly below the pad area on the surface of the outer contour of the FPC flexible board, and a cross notch is opened in the center of this area;

[0032] S4. Transformation o...

Embodiment 2

[0037] The difference from Embodiment 1 is that an installation hole for installing a cross die is opened on the upper die of the outer contour of the FPC flexible board, and the cross die is installed in the installation hole. Through the design of the mounting hole, the cross die on the outer contour die of the FPC is easy to install or disassemble and replace, and is easy to use; the length of each straight blade of the cross die is 0.75 times the width of the pad area.

Embodiment 3

[0039] Different from Embodiment 2, there are four cross notches, and two groups of cross dies are aligned up and down with the cross notches, and each group is set to two. Two cross knife dies form a group and are connected by a fixed plate or a fixed block as an integral structure and installed on the upper mold of the FPC soft board outer contour knife mold, which is convenient for structural layout and saves fixing space; and each of the cross knife molds has a The length of the word blade is 0.6 times the width of the pad area.

[0040] To sum up: the present invention provides a high-efficiency and low-cost wire-passing hole process, which saves the drilling process by simultaneously punching cross-shaped wire-passing holes during the process of punching the outer contour of the FPC soft board , improving the processing time; at the same time, the invention changes the processing technology of the wire hole, avoiding the problems of difficult waste discharge and low effi...

Abstract

The invention discloses a high-efficiency and low-cost wire-passing hole process. The high-efficiency and low-cost wire-passing process specifically comprises the following steps: producing a pad; positioning a pad region; performing FPC soft board outer contour knife mold lower mold modification; performing FPC soft board outer contour knife mold upper mold modification; performing FPC soft boardouter contour punching; and completing machining of a cross wire-passing hole. The high-efficiency and low-cost wire-passing hole process can punch the cross wire-passing hole during outer contour knife mold punching and machining of an FPC soft board, and can save the drilling process and shorten the machining time. In addition, the machining process of the wire-passing hole is changed, and theproblem that the conventional punching process is difficult to discharge waste, and the drilling process is inefficient can be solved.

Description

technical field [0001] The invention belongs to the technical field of FPC processing, and more specifically relates to a high-efficiency and low-cost wire hole technology. Background technique [0002] FPC is the abbreviation of Flexible Printed Circuit, also known as flexible circuit board, flexible printed circuit board, flexible circuit board, referred to as FPC or soft board, which has the characteristics of high wiring density, light weight and thin thickness. [0003] FPC flexible printed circuit is a kind of highly reliable and excellent flexible printed circuit made of polyimide or polyester film as the base material. It is mainly used in many products such as mobile phones, notebook computers, PDAs, digital cameras, and LCMs. [0004] In the application process of FPC, in order to match the structural requirements (in order to make the upper and lower lines of the double-sided or multi-layer boards conduct the conduction, the connection is usually realized by the ...
