This 2-layer FR4 PCBA (Printed Circuit Board Assembly) is engineered for miniature electronic devices that demand a balance of reliability, conductivity, and assembly precision, such as wireless modules, wearable electronics, and medical sensors. With dimensions of 40mm×25mm and a 1.6mm thickness, the board maximizes space efficiency while supporting dense surface-mount component placement. Constructed from FR4 material, it offers consistent electrical insulation and mechanical stability, suitable for commercial-grade applications with moderate temperature and humidity ranges.

 

The 1OZ (35μm) copper thickness on both layers optimizes signal integrity and current-carrying capacity (up to 8A per wide trace), ideal for battery-powered devices. The Red LPI solder mask provides a durable, moisture-resistant coating that protects circuitry while enabling visual differentiation in multi-board assemblies, while the White silkscreen ensures clear component marking for quality control and maintenance. The ENIG (Electroless Nickel Immersion Gold) surface finish creates a corrosion-resistant, solder-friendly surface (3–5μm nickel, 0.05–0.1μm gold), ensuring reliable connections for fine-pitch components (down to 0.3mm pitch).
