Selection of flexible circuit materials

With the continuous development of science and technology, modern society is closely related to electronic technology. Ultra-small mobile phones, portable computers, memory, hard disk drives, optical disk drives, and automotive electronic products all impose stringent requirements on the miniaturization and weight reduction of products. To achieve this goal, we must conduct in-depth discussions on aspects such as production processes, components, and materials. In order to meet this challenge, a flexible circuit that can be applied to three-dimensional electronic assembly can be bent into an infinite number of desired shapes. In recent years, the use of flexible circuits has expanded beyond 3 radio communications, computers, and automotive electronics applications. Dedicated substrate-flexible circuits that have been used as lead bundles have matured into applications that replace rigid and modular circuit boards. In these applications, there are often book-type or three-dimensional electronic assembly requirements, and in addition to being able to meet both flexibility and flexibility Rigid and rigid applications require rigid-flex technology that incorporates rigid circuit boards with flexible circuits. Many flexible and rigid-flexible laminates are now used in a variety of electronic products. This article focuses on material selection in flexible circuits.
