Flexible anti-impact circuit board

Abstract

The present invention discloses a flexible anti-impact circuit board. The circuit board comprises a circuit board body and anchorage plates. The top surface of the circuit board body is provided witha metal circuit layer, and an anti-impact transverse frame is arranged on the top surface of the metal circuit layer. An anti-impact longitudinal frame is arranged on the top surface of the metal circuit layer, wherein the anti-impact longitudinal frame is located at the perpendicular position of the anti-impact transverse frame. The bottom of the anti-impact longitudinal frame is pasted with rubber cushions, and the bottom of the anti-impact transverse frame is pasted with rubber cushions. The circuit board is provided with the anti-impact transverse frame and the anti-impact longitudinal frame, the anti-impact transverse frame and the anti-impact longitudinal frame are arc-shaped structures, and the anti-impact transverse frame and the anti-impact longitudinal frame are riveted with thecircuit board body via screw bolts. A space framework is formed over the circuit board body, when the circuit board body drops, the anti-impact transverse frame and the anti-impact longitudinal framecan keep electronic component(s) on the circuit board body from contacting with objects, and thus structural safety of the electronic component(s) and the circuit board body is ensured; and meanwhile,the anti-impact transverse frame and the anti-impact longitudinal frame have certain flexibility, and thus the anti-impact transverse frame and the anti-impact longitudinal frame play a certain roleof shock absorption when the circuit board is contacted with the objects.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a flexible and drop-resistant circuit board. Background technique [0002] The circuit board makes the circuit miniaturized and intuitive, and plays an important role in the mass production of fixed circuits and optimizing the layout of electrical appliances. The circuit board can be called an FPC circuit board, and the FPC circuit board is also called a flexible circuit board. A highly reliable and excellent flexible printed circuit board made of amine or polyester film as the base material. It has the characteristics of high wiring density, light weight, thin thickness and good bendability. FPC and The birth and development of PCB has given birth to the new product of soft and hard board. Therefore, the soft and hard board is a flexible circuit board and a rigid circuit board. After pressing and other processes, they are combined according to the relevant process require...

Problems solved by technology

[0003] Most of the circuit boards at this stage lack protection devices to prevent falling and breaking. A few circuit board manufacturers install protective shells on the outside of the circuit boards to prevent falling damage. However, it is inconvenient to ventilate after installing the protective shells, resulting in poor heat dissipation. It will also lead to a decrease in the flexibility of the circuit board. Although there are already flexible circuit boards at this stage, these flexible circuit boards cannot withstand repeated folding and bending, and the durability is not high. In view of the above problems, a flexible anti-drop type is proposed. circuit board
