    What is PCB connector

    PCB connector is made up of metal wires that have a specific shape and size for each type of connector and its purpose. Connectors come in different shapes such as round, square and rectangular etc., depending on the application they will be used for i.e., high-frequency applications require circular connectors while low frequency applications need rectangular ones.

    PCB connector is the most commonly used component in PCB. It can connect multiple types of components with each other, such as flex cable and cable, flat ribbon cable and lead wire.

    Types of PCB connector

    Several types of PCB connector is as follows: 

    ●Backplane connectors: These are the most common connectors, and include interfaces that connect a motherboard to other devices such as memory cards. They can also be used to connect external storage devices like hard drives or flash drives.

    ●Board-in connectors: These connect a board to another board or other devices in a system.

    ●Board-to-board connectors: This is used for serial communication between two boards such as serial ports, firewalls and other devices that need to communicate with each other over small distances (e.g., Ethernet).

    ●Card edge connectors: These are used for connecting cards together like USB 3 ports onto motherboards or graphics cards.

    The function and application of PCB connector

    The function and application of PCB connector

    PCB connector have broad application in electronics production. The function of PCB connector is basically to prevent physical damage, accelerate heat dissipation in electronic products, reduce noise of PCB and make the PCB schematic more flexible. Let us discuss it detail.

    ★ Prevent physical damage to PCB
    PCB connector is used to connect PCBs in different ways. They can be used for wire-to-wire connections or panel mount connectors, depending on the design. The purpose of this type of connector is to prevent physical damage to the PCB by making sure that there is no direct contact between them.

    ★ Accelerate heat dissipation in electronic product
    The PCB connector is the key components that facilitate the heat dissipation in electronic products. These connectors can be used to connect heat sinks to PCBs, which are used as a cooling system for electronic devices. Heat sinks are metal plates that absorb the excess heat generated by an electronic device such as a CPU.

    ★ Reduce noise of PCB
    The PCB connector is used to reduce noise of PCB. Noise is a common problem in electronics that may be caused by electromagnetic interference (EMI), electrostatic discharge (ESD), radio frequency interference (RFI) and transient voltage surge.

    Layout guidelines for PCB connector

    Layout guidelines for PCB connector

    The design of your PCB connector is one of the most important parts of your project. Layout guidelines for PCB connector is as follows:

    ●Minimum mounting and stacking height.
    The minimum mounting height for a connector is defined by the PCB’s routing rules, which will depend on the board manufacturer and design. For example, some manufacturers require that all SMT components be mounted directly on the PCB without any spacers or vias. In this case, you can use only one layer of copper trace; however, if you have more than one layer of tracks (like through-hole and paste in hole), then it may be necessary to add additional layers using tape soldering or other methods so that there is enough room between each pad and trace for proper contact between parts.

    ●Minimum width and spacing of pads:
    The widths should be twice as wide as they are tall—that way they won’t bump into each other when installed into a socket (e.g., an IC socket). Additionally, if two connectors share an edge between them then their pads should overlap slightly so there will not be any gaps along those edges later during assembly operations.

    ● Mounting and stacking height guidelines

    Mounting height: At least 0.1mm above the top surface of the PCB

    Stacking Height: At least 0.4mm above the top surface of the PCB

    How to use PCB connector

    Once you have the connector in place, make sure it is facing the right way up and resting on the edge of your PCB. The contacts should then be able to rest against your board without any gaps or loose bits.

    The connector has two types of contacts, male or female. The male contact is used for making connections to other conductors and female for making connections to signal traces.

    You will have to determine which type is needed before soldering or crimping in place because they are not interchangeable. Some connectors also have a housing cover which protects them from damage during use, while others do not have this feature so it’s up to you which one you need.

    When you’re working with a lot of electronic components and trying to keep them organized, it can be hard to stay organized. However, using PCB connector is a good way to make sure that your wiring stays neat and tidy.

    How to choose a proper PCB connector

    How to choose a proper PCB connector

    To choose the right PCB connector, you must first understand what your application will require. Are you trying to control power? Are you building a high-speed interface? What type of cable are you using and how much current does it carry?

    Choosing the right PCB connector is critical. It’s also a time-consuming process, so keep the following points in mind while choosing a proper PCB connector.

    ●Choose a PCB connector that matches your circuit board and cable.

    ●Check its pin count and spacing: When selecting a PCB connector suitable for mounting onto your circuit board design, there are two things that need checking: Its pin count (the number of pins) and spacing between them. 

    Both factors should match those listed in the datasheet or other documentation provided by manufacturer produces them; otherwise they won’t work reliably with other parts such as resistors/capacitors/transistors.

    Conclusion

    PCB connector is the most commonly used electrical components used in electronic products. They are used to connect the different parts of PCB and make them electrically conductive. They are also used to connect PCBs to power supply and signal lines, as well as other PCBs or external devices.
