Printed Circuit Board Connector Types

Printed Circuit Board Connector Types

Printed circuit board (PCB) connectors are used to connect electronic components to each other and to the outside world. There are many different types of PCB connectors, each with its own set of features and applications. ### Header Connectors Header connectors are the most common type of PCB connector. They consist of a row of pins on one side and a corresponding row of sockets on the other side. Header connectors are typically used to connect two PCBs together, or to connect a PCB to a cable. Header connectors are available in a variety of sizes, from small 2-pin headers to large 100-pin headers. They are also available in a variety of configurations, including straight, angled, and right-angle headers. ### Through-hole Connectors Through-hole connectors are PCB connectors that are inserted into holes in the PCB. Through-hole connectors are typically used for high-speed applications, as they provide a more secure connection than surface-mount connectors. Through-hole connectors are available in a variety of sizes, from small 2-pin connectors to large 100-pin connectors. They are also available in a variety of configurations, including straight, angled, and right-angle connectors. ### Surface-mount Connectors Surface-mount connectors are PCB connectors that are soldered directly to the surface of the PCB. Surface-mount connectors are typically used for smaller PCBs, as they do not require as much space as through-hole connectors. Surface-mount connectors are available in a variety of sizes, from small 2-pin connectors to large 100-pin connectors. They are also available in a variety of configurations, including straight, angled, and right-angle connectors. ### Receptacle Connectors Receptacle connectors are PCB connectors that have a female housing and a male pin. Receptacle connectors are typically used to connect a PCB to a cable. Receptacle connectors are available in a variety of sizes, from small 2-pin connectors to large 100-pin connectors. They are also available in a variety of configurations, including straight, angled, and right-angle connectors. ### D-sub Connectors D-sub connectors are PCB connectors that have a rectangular housing and a series of pins arranged in a D-shape. D-sub connectors are typically used for video and serial communications. D-sub connectors are available in a variety of sizes, from small 9-pin connectors to large 50-pin connectors. They are also available in a variety of configurations, including straight, angled, and right-angle connectors. ### Choosing the Right PCB Connector When choosing a PCB connector, there are a number of factors to consider, including: * The type of connection (e.g., header, through-hole, surface-mount, receptacle) * The size of the connector * The configuration of the connector * The application of the connector By considering these factors, you can choose the right PCB connector for your application. ### Conclusion PCB connectors are an essential part of any electronic system. They provide a reliable way to connect electronic components together and to the outside world. By understanding the different types of PCB connectors, you can choose the right connector for your application. ## References * [IPC-2221: Printed Board Interconnect Design and Assembly](https://www.ipc.org/standards/ipc-2221) * [JEDEC J-STD-001: Printed Board Assemblies](https://www.jedec.org/standards/j-std-001) * [IEC 61960: Printed Boards for Electronic Equipment](https://www.iec.ch/en/standards/catalogue/detail/27344-61960.html)
