New Energy Vehicle FPC: Large Flexible Circuits with Fine Line and Immersion Gold
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
General Description
This type of flexible printed circuit (FPC) is constructed on polyimide with fine line coils, specifically designed for applications in new energy vehicles. It is a 2-layer board with a thickness of 0.15mm. The base laminate is sourced from Shengyi, and the circuit is fabricated according to IPC 6012 Class 2 standards using supplied Gerber data. A polyimide stiffener is applied to the inserting part for added support.

Basic Types of Flexible Circuits
1.Single-Sided Flexible Circuits: The simplest type, consisting of a thin base material laminated with copper foil and often covered with a covercoat.
2.Double-Sided Flexible Circuits: Features copper foil laminated on both sides, frequently with covercoats on the outer sides.
3.Multilayer Flexible Circuits: Comprises multiple thin laminates and copper foils bonded together, similar to rigid multilayer boards.
4.Flex-Rigid Circuits: Combines rigid boards with flexible circuits, providing flexible interconnects.
5.Flexible Circuits with Rigid Areas: Reinforced areas for heavy components, achieved by bonding a stiffener.
