Sony LC-1024 Flexible PWB - 2-Layer Polyimide Flexible Printed Wiring Board with ENIG Finish

Compact electronic assemblies often demand interconnects that can bend, twist, and fold without compromising signal integrity. The Sony LC-1024 Flexible PWB is a two-layer polyimide flexible printed wiring board engineered for exactly those challenges. Whether you're routing signals through a hinged consumer device, a wearable medical sensor, or a space-constrained camera module, this board provides a reliable, high-flex solution that rigid PCBs simply cannot match.

Key specifications

• Base material: Polyimide (PI) for outstanding flexibility and thermal stability
• Layer count: 2-layer configuration for more complex routing than single-layer flex
• Conductor material: Electrolytic copper, 1 oz (35 µm) thickness
• Surface finish: ENIG (Electroless Nickel Immersion Gold) for excellent solderability and corrosion resistance
• Solder mask color: Yellow for easy visual inspection
• Minimum trace width/spacing: 0.1 mm (4 mil) to support fine-pitch designs
• Total board thickness: 0.15 mm with 25 µm dielectric thickness
• Operating temperature range: -40°C to +105°C
• Flammability rating: UL 94V-0
• Typical bend cycles: >1,000,000 dynamic flexes
• RoHS compliant: Yes

Why choose it

The LC-1024 is built for longevity in motion. Its polyimide base withstands repeated bending without cracking, while the ENIG finish ensures reliable solder joints even after extended storage. The two-layer design allows for more complex routing than single-layer flex, making it a versatile choice for general-purpose flexible interconnects. With over a million dynamic flex cycles, it is a dependable option for applications that require continuous movement.

Ideal use cases

• Wearable electronics and medical devices requiring flex-to-fit
• Hinged or folding mechanisms in consumer products
• Compact sensor modules and camera assemblies
• Prototyping and low-volume production of flexible circuits

Good to know

The LC-1024 is supplied as a bare flexible printed wiring board, ready for your assembly process. Its yellow solder mask provides clear contrast for inspection, and the ENIG finish offers a flat, solderable surface compatible with standard reflow and hand-soldering techniques. For high-volume production, custom panelization options may be available upon request.
