latest company case about Flexible Printed Circuit (FPC) Membrane Switch Assembly Process in Lunfeng 0

FPC membrane switches are key components in compact, durable electronics, with their assembly involving 8 precise stages to ensure functionality and reliability. Below is a concise breakdown of each step.

1. Material Selection and Inspection

The FPC, pre-fabricated with etched copper circuitry (often gold or nickel/gold plated for durability), undergoes Surface Mount Technology (SMT) if required:

3. Metal/Poly Dome Placement (Tactile Designs)

A spacer (polyester/polyimide with adhesive) with die-cut openings over switch areas is applied. It creates an air gap to prevent accidental actuation, defines actuation travel, and protects internal components.

5. Graphic Overlay Lamination

Flexible FPC tails (with exposed pads/connectors) are terminated via crimped connectors, direct soldering to PCBs, or stiffeners for socket insertion—chosen based on application needs.
7. Electrical Testing and Final Inspection
- Continuity/open circuit test: Checks for unintended connections.
- Short circuit test: Verifies isolation between circuits.
- Switch function test: Confirms correct actuation and signal output (including tactile "snap" feel for domes).
Final visual inspections check for cosmetic defects (scratches, misalignment) and dimensional compliance.
