Samsung liitin board to board (3710-004285)

Ultra-low-profile board-to-board receptacle with fine pitch and gold-plated contacts for high-density internal connections in compact mobile devices.

Overview

The Samsung 3710-004285 is a board-to-board (BTB) socket designed for internal data and power transfer between printed circuit boards. It features a vertical surface-mount (SMT) receptacle with fine pitch, enabling high-density connections in space-constrained applications. The contact system uses copper alloy with gold plating for reliable signal integrity and durability.

What stands out

• Fine pitch (0.4–0.5 mm) supports high pin counts in minimal board area.
• Ultra-low stack height suits slim mobile device designs.
• Gold-plated contacts ensure low contact resistance and corrosion resistance.
• High-temperature thermoplastic insulator withstands reflow soldering.
