A Printed Circuit Board (PCB) is a crucial component in electronics, and it relies on connectors to connect different parts and components. PCB board connectors are vital in establishing an electrical connection between two different PCBs or between a PCB and an external device. They come in different types, sizes, and configurations to meet the diverse requirements of electronic applications.
Types of PCB Board Connectors
Pin Headers: Pin headers are one of the most commonly used PCB connectors and are typically used to connect daughterboards or PCBs. These types of connectors are available in different pitch sizes and pin counts to fit various application requirements
Terminal Blocks: Terminal blocks are used for connecting wires to a PCB. They have a screw terminal that tightens onto the wire, providing a secure electrical connection. Terminal blocks are commonly used in industrial and control applications.
D-Sub Connectors: In order to connect computer peripherals, such as printers, keyboards, and mice, D-Sub connectors are used. These connectors have pin counts ranging from 9-pin to 25-pin configurations.
Board-to-Board Connectors: Board-to-board connectors are preferred to connect two PCBs together. They are available in various configurations, including vertical and right-angle connectors.
USB Connectors: USB connectors are used to connect devices to a computer or other electronic device. Different types of USB connectors are available in the market, including USB Type-A, Type-B, and Type-C.
FFC/FPC Connectors: FFC (Flexible Flat Cable) or FPC (Flexible Printed Circuit) connectors are used to connect flexible circuits to PCBs. Portable electronics and mobile devices consist of such connectors.
Factors to Consider When Selecting PCB Board Connectors
Pin Count: The pin count of a connector refers to the number of pins or contacts that the connector has. Choosing a connector with the right pin count is essential to ensure a proper electrical connection. Also, all boards don’t need the same pin count. Check your device requirement and buy accordingly.Â
Pitch: The distance between two adjacent pins is considered the pitch of a connector. The right pitch is important to match the spacing on the PCB.Â
Height: The height of a connector is the distance from the PCB to the top of the connector. The proper height of a connector is required to ensure clearance for other components on the PCB.
Current and Voltage Ratings: A connector’s current and voltage ratings determine the maximum current and voltage that the connector can safely carry. It is important to ensure the right voltage ratings in the connector for the safe operation of the device.
Durability: PCB connector accessories you’re buying should have a long life span. Buy from those services that ensure the excellent durability of their product. It will help you prevent frequent insertions and removal of PCB connectors and boards.Â
The Summary
PCB board connectors are essential to establish an electrical connection between two or more components. In order to choose the right type of connector, factors such as pin count, pitch, height, current and voltage ratings, and durability are needed to be considered according to the requirements.
