  • Description

  • Data Sheet

Flexible Printed Circuit (FPC) is a high-reliability flexible circuit substrate fabricated with polyimide or polyester film as core raw materials. Featuring outstanding bending ductility, high wiring density, ultra-light weight and ultra-thin thickness, it serves as a core interconnection component for miniaturized and portable electronic devices.

Core Performance & Development Characteristics of FPC

  1. Ultra-thin structural design
    FPC adopts customized thin substrate configuration to ensure excellent flexibility, adapting to compact internal assembly space of precision electronics.
  2. Superior bending resistance
    Repeated dynamic bending is the inherent core capability of flexible circuits. With high-performance base material upgrading, modern FPC can achieve a bending life of over 10,000 cycles, greatly improving long-term service stability.
  3. Cost optimization potential
    At present, the comprehensive manufacturing cost of FPC is higher than conventional rigid PCB. With the continuous scale-up of industrial production and mature process iteration, the overall cost will gradually decrease, further expanding the market application coverage.
  4. High-precision process iteration
    To meet the upgrading demand of high-density electronic products, FPC manufacturing technology is continuously optimized. The industry keeps lowering the limits of minimum aperture, line width and line spacing to support finer and more complex circuit design.

FPC for Fingerprint Identification Module

The fingerprint identification module is a key core component widely used in smart locks, access control equipment, mobile terminals and storage devices, which undertakes fingerprint collection, identification analysis and signal transmission. The complete module consists of fingerprint acquisition unit, identification processing unit and extended functional control unit, among which customized FPC is an indispensable connecting carrier for signal interaction.
According to different identification principles, mainstream fingerprint FPC modules are classified into three categories:
  • Optical fingerprint module: Realizes fingerprint pattern identification through optical refraction and reflection sensing technology;
  • Capacitive fingerprint module: Captures fingerprint feature information by detecting subtle changes of capacitance values;
  • RF fingerprint module: Detects skin surface texture through low-power radio frequency signals to complete high-precision identification.

  1. Optical fingerprint module, which can identify fingerprint by refraction and reflection of light;
  2. The capacitance fingerprint module collects the fingerprint by the value change of capacitance;
  3. The RF fingerprint module (scratch fingerprint module) uses a small amount of RF signal to detect the texture.
