A flexible printed circuit board

Abstract

The invention provides a flexible printed circuit board and relates to the technical field of circuit boards. The flexible printed circuit board includes a circuit board body, a base layer is arranged in the circuit board body, a reinforcement layer is provided at the bottom of the base layer, and an insulating layer is provided at the top of the base layer and the bottom of the reinforcement layer, two The outer surface of the insulating layer is provided with a flame retardant layer, the two ends of the circuit board body are provided with connecting frames, one side of the outer surface of the connecting frame is fixedly connected with a rear clamping block, and the clamping A connection piece is arranged on the connection block, and a plurality of socket holes are evenly distributed on the connection piece. The tear resistance of the entire flexible printed circuit board can be enhanced through the setting of the strengthening layer. The insulating layer and the flame-retardant layer can not only ensure the structure has a stable insulation and flame-retardant effect, but also ensure that the structure is wear-resistant and durable. The joint structure on the provided connecting frame can carry out convenient and stable line docking and installation work.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a flexible printed circuit board. Background technique [0002] Flexible circuit board, also known as flexible circuit board and flexible circuit board, is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film. It is favored for its excellent characteristics such as light weight, thin thickness, and free bending and folding. [0003] With the development of technology, the use of flexible printed circuit boards is becoming more and more common. Although some conventional flexible printed circuit boards can be bent freely, their overall structural strength is not strong enough and their tear resistance is not strong. In the case of breakage, at the same time, some conventional flexible printed circuit boards have insufficient insulation and flame retardant properties, and the durability and safety of the structure are not good, ...

Problems solved by technology

[0003] With the development of technology, the use of flexible printed circuit boards is becoming more and more common. Although some conventional flexible printed circuit boards can be bent freely, the overall structural strength is not strong enough, and the tear resistance is not strong. At the same time, some conventional flexible printed circuit boards lack insulation and flame retardancy, poor structural durability and safety, and some conventional flexible printed circuit boards have joint structures that are often The spot welding method is used for docking, which is not only very inconvenient to operate, but also needs to be forcibly cut off after subsequent disassembly, which will easily lead to the failure of normal use of the structure
