A flexible circuit board wiring method

Abstract

The invention discloses a flexible circuit board wiring method, which belongs to the technical field of flexible circuit boards. The invention can replace traditional wiring methods such as welding by introducing a wiring barrel, and can be supplied by means of large-scale prefabrication. When wiring, only the circuit The self-contained leads on the board and the external leads of external components can be inserted into the junction barrel. The adaptable film in the junction barrel is preheated and softened in advance. It can rely on the magnetic attraction for independent docking and positioning, and then cool the wiring barrel to semi-permanently position the main conductive ball after the film is solidified. When it needs to be separated, it can be taken out by reheating, and it can be adapted to the film on the actual use process. The auxiliary conductive ball can release the conductive liquid to improve the electrical conductivity between the main conductive balls, so as to realize efficient and convenient wiring while having good electrical conductivity.

Description

technical field [0001] The present invention relates to the technical field of flexible circuit boards, and more specifically, relates to a flexible circuit board wiring method. Background technique [0002] Flexible circuit boards, also known as "soft boards", are printed circuits made of flexible insulating substrates. Flexible circuits provide excellent electrical performance, can meet the design needs of smaller and higher density mounting, and also help reduce assembly processes and enhance reliability. Flexible circuit boards are the only solution to meet the miniaturization and mobility requirements of electronic products. It can be bent, wound, and folded freely, and can withstand millions of dynamic bendings without damaging the wires. It can be arranged arbitrarily according to the spatial layout requirements, and can be moved and stretched in three-dimensional space, so as to achieve the integration of component assembly and wire connection. The flexible circuit...

Problems solved by technology

[0004] At present, when the flexible circuit board is connected with the components outside the board, welding or printed board socket is generally used. There are many interference factors in the welding quality. The solderability of the circuit board hole affects the welding quality, and the solderability of the circuit board hole If it is not good, there will be virtual soldering defects, which will affect the parameters of the components in the circuit, resulting in unstable conduction between the multilayer board components and the inner layer wires, causing the entire circuit function to fail, and the circuit board and components to warp during the welding process , Due to stress deformation, defects such as virtual soldering and short circuit occur, and the design of the circuit board itself will also interfere with the welding quality, and the welding process is relatively cumbersome, and it is also highly harmful to the human body. The disadvantage of the printed board socket is the cost of the printed board Improvement, high precision and process requirements for printed board manufacturing, slightly poor reliability, often due to oxidation of the plug part and poor contact, so a new wiring method is urgently needed to improve the wiring quality of flexible circuit boards
