• Superior Conductivity: Features gold-plated contacts ensuring low resistance, excellent corrosion resistance, and long service life.
• High Precision: Supports fine-pitch design and high-density interconnection, perfect for miniaturized electronic devices.
• Custom Solutions: Expert OEM/ODM service for single, double, and multi-layer FPCs with strict quality control.

Bespoke Flex-Rigid PCBs for Consumer Electronics, Automotive, and Industrial Equipment:

• Consumer Electronics: Smartphones, wearables, tablets, and laptops (compact, flexible internal connections).
• Automotive Electronics: In-vehicle cameras, sensors, radar, displays, and BMS (reliable, vibration-resistant).
• Medical Devices: Portable monitors, hearing aids, and implantable devices (miniaturized, stable).
• Aerospace & Defense: Drones, satellites, radar, and communication systems (extreme-environment reliability).
• Industrial IoT: Robotics, sensors, and security cameras (flexible joints, rugged use).

The production process for Flexible PCBs (FPCs)

1. Design & Engineering

• Requirements Analysis: Confirm substrate type (Polyimide/PI), coverlay options, bend cycle requirements, and surface finish (ENIG, Immersion Tin).
• DFM Review: Engineers optimize the design, particularly the bend areas, to ensure reliability and manufacturability.

2. Material Preparation

• Substrate Selection: High-performance Polyimide (PI) film with copper cladding is used for its heat and flex resistance.
• Coverlay Prep: A protective insulating film (Coverlay) is cut to shape to cover the circuits.

3. Circuit Fabrication

• Patterning: Circuit patterns are transferred onto the copper foil using photolithography.
• Etching: Unwanted copper is chemically removed, leaving the desired conductive traces.

4. Coverlay Lamination

• Lamination: The coverlay is applied over the bare copper traces to provide insulation and protection against oxidation and mechanical damage.

5. Surface Finish & Shaping

• Surface Treatment: Solder pads are finished (e.g., ENIG) to ensure good solderability.
• Profiling: Laser cutting (most common for precision) or die cutting is used to trim the board to its final shape.
• Stiffener Application: Stiffeners (steel or FR-4) are added to areas requiring rigidity for connector insertion or heavy component mounting.

6. Testing & Packaging

• Electrical Testing: Flying probe or fixture testing ensures circuit integrity.
• Reliability Testing: Flex endurance tests simulate real-world bending conditions.
• Packaging: FPCs are typically packaged on reels (tape-and-reel) or interleaved sheets to prevent damage.
