2、 Structure and Materials-深圳市海博精密电路有限公司

Structure: Blind hole FPC is usually composed of multiple layers, including conductive layers, insulation layers, and cover films. The buried holes are located between these layers, while blind holes enter from one side and end at a certain depth.

Conductive layer: Made of high conductivity copper foil material to ensure stable signal transmission.
Insulation layer: Insulation materials with excellent dielectric and heat resistance properties, such as polyimide (PI) or polyester (PET), are used to protect conductive lines and prevent signal interference.
Cover film: used to protect circuits and components, preventing damage to circuit boards from external environments.
