40-Pin Black Vertical PCB Header – Technical Description A 40-pin black vertical PCB header is a high-density interconnect component designed for printed circuit board (PCB) applications, providing reliable electrical connections in compact electronic assemblies. This header features a vertical orientation, allowing perpendicular mounting to the PCB, which optimizes space utilization in tight layouts. Construction & Design The header consists of 40 conductive pins arranged in a single or double row (typically 2x20 configuration), housed in a durable black thermoplastic insulator. The black color provides a neutral, professional appearance while aiding in part identification. The insulator material, often high-temperature nylon or polyamide, ensures mechanical stability and resistance to soldering heat. Pins are made of phosphor bronze or brass, plated with gold or tin for enhanced conductivity and corrosion resistance. The gold plating offers superior signal integrity in high-frequency applications, while tin plating provides a cost-effective solution for general-purpose use. Pin spacing follows standard 0.1-inch (2.54 mm) pitch, ensuring compatibility with breadboards, sockets, and ribbon cables. Key Features - Vertical Orientation: Enables perpendicular PCB mounting, ideal for stacking boards or connecting cables vertically. - High-Density Interconnect: Supports up to 40 signals in a compact footprint. - Secure Mounting: Features friction locks or solder tabs for stable PCB attachment. - Wide Temperature Range: Operates reliably from -40°C to +105°C, suitable for industrial environments. - RoHS Compliance: Free from hazardous substances, meeting environmental regulations. Applications This header is widely used in: - Embedded Systems: Connects microcontrollers, sensors, and peripheral modules. - Consumer Electronics: Facilitates board-to-board or board-to-wire connections in devices like printers and IoT gadgets. - Industrial Automation: Interfaces control boards, motor drivers, and communication modules. - Prototyping: Compatible with breadboards and development kits for rapid testing. Installation & Compatibility The header is soldered onto the PCB via through-hole or surface-mount technology (SMT). Its vertical design minimizes horizontal space usage while maintaining robust mechanical retention. Mating connectors include IDC (Insulation Displacement Connector) cables, female headers, or shrouded connectors for secure coupling. Conclusion The 40-pin black vertical PCB header is a versatile, high-performance interconnect solution for modern electronics. Its durable construction, standardized pitch, and space-saving design make it essential for applications requiring reliable signal transmission in constrained spaces. Whether for prototyping or mass production, this header ensures efficient and stable connectivity.
