Product Overview

This product is a single-sided printed circuit board with tin-sprayed surface treatment, designed for reliable solderability, efficient heat dissipation, and cost-effective electronic manufacturing.

The tin-sprayed layer provides a uniform protective coating that improves surface conductivity and prevents oxidation of the copper pads during assembly and storage.
