This compact 2-layer FR4 PCB is engineered for miniature electronic devices that demand a balance of reliability, conductivity, and cost-effectiveness, such as wearable technology, IoT sensors, and medical diagnostics. With dimensions of 15.60mm×6.40mm and a 1.0độ dày mm, the board maximizes space efficiency while maintaining mechanical stability for surface-mount component assembly. Xây dựng từ FR4 material, it offers consistent electrical insulation (Hằng số điện môi εr = 4,5) and thermal resistance suitable for commercial-grade applications.
Các 1.5Oz (52μm) Độ dày đồng on both layers optimizes current-carrying capacity (up to 10A per wide trace) while minimizing board weight—ideal for battery-powered devices where power density and longevity are critical. Các Blue LPI (Liquid Photoimageable) solder mask provides a durable, moisture-resistant coating that protects circuitry from environmental damage, Trong khi Silkscreen trắng ensures clear component marking on the miniature surface, aiding assembly and maintenance in tight layouts. Các HASL (Hot Air Solder Leveling) surface finish creates a uniform, solder-friendly coating of eutectic tin-lead (or lead-free SAC alloy), promoting reliable soldering even for fine-pitch components (down to 0.5mm pitch).
Manufactured in a 10×10 panel format, the PCB enables cost-effective mass production by minimizing material waste and streamlining pick-and-place assembly. Each panel contains 100 identical boards, connected by micro-vias or breakaway tabs for easy depaneling without damaging delicate circuitry. This format is ideal for OEMs requiring high-volume production of miniature devices, such as wireless modules or sensor nodes.
