Printed circuit boards, or PCBs, are used in various electronic devices to provide electrical connectivity between the different components of the device. To properly connect these components, PCB connectors are used. PCB connectors come in various shapes and sizes, and each type has its specific purpose. This blog post will explore the basics of PCB connectors, including what they are and why you need them. By the end of this blog, you should better understand how these essential components work and how they can be used in your next electronics project.
What are PCB connectors?
PCB connectors are electrical connectors that join printed circuit boards (PCBs). They come in various shapes and sizes and are used to connect different types of PCBs and connect them to other electronic components.
Why do you need them? If you’re designing or assembling a PCB, chances are you’ll need to use some connector to join it to another PCB or another electronic component. Connectors make it possible to create electrical connections without having to solder everything together, making the whole process easier and faster.
Many types of connectors are available, but the pin header is the most common type used in PCB design. Pin headers come in male and female varieties and consist of a row of metal pins that connect with the pads on a PCB. Male pin headers have their pins exposed, while female pin headers have sockets that the pins fit into.
Other types of connectors include D-subminiature, IDC, and FPC/FFC. D-subminiature connectors are used in computer applications, while IDC connectors are typically used for connecting ribbon cables. FPC/FFC connectors are used for connecting flexible printed circuits (FPCs) or flat flexible cables (FFCs) to PCBs.

The Different Types of PCB Connectors
There are many PCB connectors, each with unique benefits and drawbacks. The most common types of connectors are through-hole, surface-mount, and pin headers.
Through-hole connectors are the easiest to work with and are the most reliable. However, they require a giant hole to be drilled in the PCB, which can increase the cost. Surface-mount connectors are more miniature and more difficult to work with, but they do not require drilling a hole in the PCB. Pin headers are the most difficult to work with, but they offer the best electrical connection.
How to Select the Right PCB Connector
When it comes to picking the suitable PCB connector for your needs, there are a few things you need to take into account. Firstly, you need to assess the number of pins on the connector. More pins mean more electrical connections can be made. However, more pins also represent a larger footprint for the connector, which can impact your board layout.
Another critical factor is the pitch of the connector – that is, the distance between adjacent pins. A smaller pitch means finer pitch connectors can be used, which is vital for high-density applications. Conversely, a larger pitch makes inserting and removing cables from the connector easier.
Finally, choosing the connector’s mating style would be beneficial. The two most common options are surface-mount (SMT) and through-hole (THT). SMT connectors are typically more miniature and more suitable for densely packed circuit boards. In contrast, THT connectors offer more robust mechanical support and are easier to work with during prototyping and assembly.
Why do you need a PCB connector?
If you’ve ever worked with a printed circuit board (PCB), you know that it can be delicate. You don’t want your PCB to be damaged during the assembly process. That’s where PCB connectors come in.
PCB connectors are designed to protect your PCB from damage during the assembly process. They also help to keep your PCB securely in place so that it doesn’t move around and cause shorts or other problems.
Many PCB connectors are available, so you’ll need to choose the right one for your project. But regardless of which type you select, PCB connectors are essential to any printed circuit board assembly.
Conclusion
As you can see, PCB connectors are highly versatile and have many applications. Whether you need to connect two boards or want to create a reliable connection between your PCB and another device, these connectors are worth considering. Do some study to figure out which type of connector would be best for your project, and don’t hesitate to ask for help if you’re unsure which one to choose.
