Flexible circuit boards, also known as FPCs or flexible printed circuit boards, are often referred to as soft boards or FPCs. They boast high wiring density, lightweight construction, and thin profiles, making them ideal for various applications including mobile phones, notebook computers, PDAs, digital cameras, and LCMs. The FPC offers three key attributes: flexibility, reliability, and cost-effectiveness. Constructed from polyimide or polyester film, it ensures both high reliability and exceptional flexibility in circuit design.

In industrial production, FPC circuit boards come in various structures and technologies to meet specific requirements. These include single-sided boards, double-sided boards, multi-layer boards, rigid-flex boards, and specialized craft boards. When it comes to their application, principles for heat dissipation of flexible circuit boards must be adhered to.
