Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to an antistatic flexible circuit board. Background Art

[0002] Flexible circuit board is a kind of printed circuit board with high reliability and excellent flexibility made of polyimide or polyester film as the base material. It is called soft board or FPC for short. It has the characteristics of high wiring density, light weight and thin thickness. The circuit components on the existing flexible circuit board are more precise than those on the rigid circuit board. When static electricity is discharged instantly, the voltage generated is relatively large. If static electricity is generated near the flexible circuit board, the static electricity is likely to damage the electrical components on the flexible circuit board, resulting in the scrapping of the entire flexible circuit board. The existing flexible circuit board is usually installed by glue, which cannot be disassembled and installed for later maintenance and is inconvenient to use. Therefore, we have launched an anti-static flexible circuit board. Utility Model Content
