35-Pin Black PCB Header: Technical Overview A 35-pin black PCB header is a compact, high-density interconnect component designed for printed circuit board (PCB) applications. It features 35 conductive pins arranged in a single or dual-row configuration, housed within a durable black plastic insulator. The black color provides a sleek, professional appearance while offering UV resistance and improved contrast for visual inspection during assembly. Key Features 1. Material & Construction - Pins: Typically made of phosphor bronze or brass, plated with gold, tin, or nickel for corrosion resistance and reliable conductivity. - Insulator: High-temperature thermoplastic (e.g., PA6T, PBT) ensures mechanical stability and flame retardancy (UL94V-0 rated). 2. Pin Configuration - Available in straight or right-angle orientations for vertical or horizontal PCB mounting. - Standard pitch options include 2.54mm (0.1") or 2.00mm, supporting high-density layouts. 3. Electrical & Mechanical Performance - Current Rating: 1–3A per pin, depending on material and plating. - Voltage Rating: Up to 250V AC/DC. - Mating Cycles: 500+ insertions, ensuring longevity. 4. Compatibility - Matches standard 35-pin sockets or IDC connectors for ribbon cables. - RoHS and REACH compliant for environmental safety. Applications - Industrial Electronics: Control boards, sensor interfaces. - Consumer Devices: Embedded systems, display modules. - Automotive: ECU connections, infotainment systems. Advantages - Space-Efficient: Ideal for compact PCB designs. - Reliable Contact: Precision-molded pins prevent misalignment. - Cost-Effective: Mass-production friendly with automated pick-and-place compatibility. Installation Notes - Soldered via through-hole (THT) or surface-mount (SMT) methods. - Recommended reflow profile: 260°C max for SMT variants. In summary, the 35-pin black PCB header is a versatile, durable solution for secure signal and power transmission in modern electronics. Its robust design and compliance with industry standards make it suitable for demanding applications.
