Description

Connector, connector assembly and electronic device

The present invention relates to a connector, and more particularly to a connector that is electrically connected to a printed circuit board.

Flexible Printed Circuit Board (FPC) is a printed circuit made of a flexible insulating substrate that has many advantages that are not provided by rigid printed circuit boards. For example, it can be freely bent, wound, folded, can be arbitrarily arranged according to the spatial layout requirements, and can be arbitrarily moved and expanded in a three-dimensional space, thereby achieving integration of component assembly and wire connection. The use of flexible printed circuit boards can greatly reduce the size of electronic products, and is suitable for the development of electronic devices in the direction of high density, miniaturization, and high reliability. Therefore, flexible printed circuit boards are used in aerospace, military, mobile communications, laptop computers, and computer peripherals. , PDA, digital camera and other fields or products have been widely used.

Flexible printed circuit boards are available in single, double and multi-layer boards. The substrate used is mainly polyimide-copper-clad laminate. The material has high heat resistance and good dimensional stability, and is formed into a final product by pressing with a cover film having both mechanical protection and good electrical insulation properties. The polyimine resin is a general term for a heat-resistant resin having a penta-nine ring of an imine, represented by polyphenyltetramethylene imide produced by the reaction of an oxygen-containing layer and anhydrous pyromellitic acid. The conductors for flexible printed circuit boards are thin foil-like copper, which is a so-called copper foil. The preparation method can be divided into electrolytic copper foil and rolled copper foil, in which pressure is applied. Copper foil is the mainstream. In addition, the surface layer and the inner layer conductor of the double-sided, multilayer printed wiring board are electrically connected to each other by metallization.

However, flexible printed circuit boards can be used in low-performance, low-operating frequency environments, as well as in high-performance, high-operating frequency environments. In order to be suitable for use in a higher operating frequency environment, the structural design and manufacturing process of a flexible printed circuit board is relatively difficult and costly. This is because the electromagnetic interference (EMI) between the signal lines on the same film layer and the signal lines on the adjacent film layers will become apparent, which will affect the signal transmission quality.
