Product Overview
Our 2-layer HDI PCBs are purpose-built for Electronic Shelf Labels (ESL) and smart retail display modules. Featuring advanced micro-via technology and an ultra-slim profile, these boards are optimized for low-power consumption and long-term battery efficiency. Designed to support E-ink displays and wireless communication (Zigbee/Bluetooth), our boards provide the high-density routing required for compact, energy-efficient retail hardware. We ensure superior signal integrity and surface flatness, making them the ideal choice for high-volume, cost-effective smart labeling systems.
Key Selling Points
•Ultra-Slim: Compact 2-layer HDI design for thin ESL enclosures.
•Low Power: Optimized routing for extended battery life.
•High Volume: Cost-effective OEM production for smart retail.


Engineering Support: DFM (Design for Manufacturing) check before production.

Testing: Flying Probe Test, Fixture Test, Impedance Control Test, Thermal Stress Test.
