Method for efficient FPC board division

Abstract

The invention discloses a method for efficient FPC board division. The method belongs to the technical field of FPC assembly. The method provided by the invention comprises the steps that an FPC board splicing manner is analyzed and an FPC board splicing template is established according to FPC design data; according to the board splicing template, a punching machine lower die is selected for FPC supporting; a FPC fixation manner is disposed; FPC displacement is avoided during the board division; a punching machine upper die is disposed, and an installation direction and an installation position of a cutter are determined; and a moving track and a stepping distance of the lower die are set according to the stamping die cutter which is disposed by the FPC board splicing template on the upper die, so that the FPC board division can be completed.

Description

technical field [0001] The invention discloses a method for dividing boards, belongs to the technical field of FPC assembly, and in particular relates to a method for dividing boards of FPCs with high efficiency. Background technique [0002] FPC (Flexible Printed Circuit) is a printed circuit made of a flexible insulating substrate. Flexible circuit board is a kind of highly reliable and excellent flexible printed circuit board made of polyimide or polyester film as the base material. It has the characteristics of high wiring density, light weight, thin thickness and good bendability. According to the characteristics of the material of the flexible circuit board and its wide application fields, in order to save volume more effectively and achieve a certain accuracy, the characteristics of three-dimensional space and thin thickness are better applied to digital products, mobile phones and notebook computers. These advantages of FPC different from ordinary PCB determine tha...

Problems solved by technology

These advantages of FPC different from ordinary PCB determine that the single board area of ​​FPC is small in actual design and application. In order to facilitate subsequent PCBA processing, FPC often adopts the method of multi-panel board. FPC sub-board is different from PCB using CNC milling machine and V-cut Cutting machine splitting, because FPC is light and thin and extremely flexible, in the splitting process of FPC assembly factories, the punching splitting currently used requires a sufficient amount of tools to be installed on the upper and lower dies and upper dies of the punching machine for one-time punching There are multiple connection points on the entire FPC board, so as to achieve the purpose of separating the FPC single board from the whole board. The limitation of this method is that the area size of the punch mold is limited by the FPC. Combined with the FPC, it is generally a multi-joint board, and the weight of the mold is relatively heavy. It is not convenient for subsequent use and maintenance; and the tools installed on the upper mold will be damaged and aged with the passage of time, requiring the user to perform corresponding maintenance, which is not conducive to cost saving
