A Pin Header Board PCBA is a customizable printed circuit board assembly featuring precision pin headers (single/double-row) for secure interconnections in modular electronic systems. Designed for flexibility and durability, these boards support 2.54mm or 1.27mm pitch headers with brass/phosphor bronze pins plated with gold or nickel to ensure low-contact resistance and corrosion resistance. Compliant with IPC-A-610, RoHS, and UL standards, they operate in temperatures from **-40°C to +105°C**, making them ideal for automotive, industrial, and IoT applications. Key features include THT/SMT mounting options, high-current handling (3–5A per pin), and compatibility with multi-layer FR4 PCBs for signal integrity. Manufacturers like TE Connectivity and Amphenol offer custom configurations to streamline prototyping and mass production.
