Problems solved by technology

This is inseparable from many characteristics of flexible circuit boards, such as excellent bending resistance, weldability, ultra-thin volume and low cost, and many other advantages. At present, it has been involved in all aspects of various industries, and its role is extraordinary, so for To ensure product quality and improve product service life, the design of the flexible circuit board is very important. At present, the pad fingers connected to the backlight in the flexible circuit board are easy to break fingers during the actual welding or hot-pressing production process, resulting in bad backlight. Brightness, which seriously affects the display function and product yield of the product

Embodiment Construction

[0012] The present invention is described in detail with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following examples.

[0013] An FPC pad, comprising a base material 1 and a wiring 2 arranged on the base material, an upper coating film 3 is arranged on the wiring, and the upper coating film is exposed on the wiring by opening a window at one end of the wiring The copper foil forms the pad 4, and the second wire 5 is drawn out from the common end of the wire on the pad to connect to the middle of the wire on the pad. In this way, the second wiring opening can play a better reinforcing role, prevent the pad from being pulled up, and increase the adhesion of the entire pad; when the wiring breaks at the edge of the pad, the second wiring can also It plays a conduction role and will not affect the normal use of the FPC.

[0014] Preferably, an extension part 6 is provided at one end of the pad trace, and the e...

Abstract

The invention discloses an FPC (flexible printed circuit) welding disc which comprises a substrate and walking lines arranged on the substrate. An upper covering film is arranged on the walking lines, copper foil on each walking line is exposed by forming a window at one end of the walking line by the upper covering film to form a welding disc body, and a second walking line is led out at the public end of each welding disc walking line to be connected in the middle of the welding disc walking line. The FPC welding disc is firmer and capable of lowering product reject rate.

Description

technical field [0001] The invention relates to a flexible circuit board, in particular to an FPC pad. Background technique [0002] Due to the technical development of electronic products, the display screen as a human-machine interface is acting as a display of more functions. The use of flexible circuit boards (FPCs) connected to displays is also becoming more and more widespread. This is inseparable from many characteristics of flexible circuit boards, such as excellent bending resistance, weldability, ultra-thin volume and low cost, and many other advantages. At present, it has been involved in all aspects of various industries, and its role is extraordinary, so for To ensure product quality and improve product service life, the design of the flexible circuit board is very important. At present, the pad fingers connected to the backlight in the flexible circuit board are easy to break fingers during the actual welding or hot-pressing production process, resulting in ba...
