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. Avec des dimensions de 15.60mm×6.40mm et un 1.0mm d'épaisseur, the board maximizes space efficiency while maintaining mechanical stability for surface-mount component assembly. Construit à partir de Matériau FR4, it offers consistent electrical insulation (constante diélectrique εr = 4,5) and thermal resistance suitable for commercial-grade applications.

 

Le 1.5Oz (52μm) épaisseur de cuivre 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. Le Blue LPI (Liquid Photoimageable) solder mask provides a durable, moisture-resistant coating that protects circuitry from environmental damage, Pendant que le Écran à soigneux blanc ensures clear component marking on the miniature surface, aiding assembly and maintenance in tight layouts. Le 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.
