Printed circuit board connectors (more often shortened as PCB connectors) are a type of electrical connector made up of a housing and contacts that join sections of circuits together on PCBs, namely boards where conductive tracks for electronic components are printed.
There are a variety of PCB connectors and accessories best designed for specific uses. To name some, they include:
Backplane connectors are mostly used to design computer systems due to their versatility and modularity. They are support structures used to connect different PCBs. Their cards can be interchanged very easily therefore, they are highly used in the telecom industry.
Also called Low Voltage Differential Signalling connectors, LVDS connectors are typically used in monitors. One of their benefits is that the copper cables allow for high speed of connection despite the low power operation.
When paired with PCB headers, PCB sockets are used to guarantee simplified assembly when connecting two printed circuit boards without cabling.
Their acronym stands for Remote Input/Output Terminal System. They are colour-coded to indicate their applications and feature a locking lever that facilitates the mating process without the need to strip the wires in preparation, which is required by other types of PCB connectors.
PCB connectors offer several advantages that make them indispensable in modern electronics. Their primary function is to create reliable and efficient electrical connections between different PCBs or between a PCB and external devices. They provide a modular approach to design, allowing for easy assembly, maintenance, and upgrades, simplifying the overall design process and reducing downtime during repairs or modifications. Additionally, PCB connectors ensure secure and consistent connections, minimising signal loss and interference, crucial for maintaining signal integrity and preventing performance issues.
PCB connectors find widespread use across major industries, facilitating seamless communication and power transmission in diverse applications.
When selecting a printed circuit board connector, you should first determine the specific type required for your application. There are various PCB connector types, including headers, sockets, plugs, terminal blocks, and more, each designed for specific purposes.
Next, consider the number of pins or contacts needed to ensure compatibility with your PCB and the devices it will connect to. You must pay close attention to the connector's pitch, which is the distance between the pins, to ensure it matches the spacing on your board.
Additionally, consider the current and voltage ratings of the connector to ensure they are suitable for your application. Other important factors to consider include the material and plating of the connector, its durability, and its resistance to environmental factors such as moisture and temperature. Finally, ensure that the connector is compliant with relevant industry standards to ensure safety and reliability.
Cleaning is an essential part of maintenance for the good functioning of PCB connectors and electronic devices in general. PCB connectors are likely to accumulate dirt, especially if they are not used every single day. This eventually leads to corrosion, making the printed circuit connector unusable. Carrying out a cleaning routine enables you to avoid power loss and maintain good contact. Please note that the right tools are required in order not to damage parts that come in contact with the circuits. Here are some key things to note for cleaning and maintaining your circuit board plugs:
