The Basics of PCB Connectors: Why You Need Them

In various electronic devices, printed circuit boards (or PCBs) are used to provide electrical connectivity among the different parts. These connectors allow you to connect the components properly. There are many sizes and shapes of PCB connectors , each with its own purpose. This blog will explain the basics of PCB connectors. It will also discuss why they are important. This blog will help you to understand the basics of PCB connectors and how they can be applied in your next electronic project.

What is a PCB connector?

The PCB connectors connect printed circuit boards (PCBs) together. They are available in a variety of sizes and shapes. They can be used to connect various types of PCBs to other electronic components.

Why are they necessary? Connectors are necessary to connect a PCB to another PCB or other electronic component. The connectors allow you to make electrical connections without the need to solder. This makes it easier and quicker.

There are many types of connectors, but the most commonly used for PCB design is the pin header. Pin headers are available in male and female versions. They consist of a row or metal pins that connect to the pads of a PCB. Pin headers for males are exposed while pin headers for females have pin sockets.

D-subminiature connectors, IDC and FPC/FFC are all other types. D-subminiature connectors can be used in computer applications. IDC connectors, on the other hand, are commonly used to connect ribbon cables. FPC/FFC connectors can be used to connect flexible printed circuits (FPCs), or flat flexible cables (FFCs), to PCBs.

Different Types Of PCB Connectors

There are many types of PCB connectors available, each with its own benefits and drawbacks. Pin headers, surface-mount, through-hole and surface-mount connectors are the most popular.

Through-hole connectors can be the most straightforward to use and the most reliable. They require drilling a huge hole in the PCB to work with, which can lead to higher costs. Surface-mount connectors require less drilling than conventional PCB holes. However, they are smaller and easier to use. The pin headers offer the best electrical connection, although they are the most difficult to use.

How to Choose the Right PCB Connector

There are several things to consider when choosing the right PCB connector. First, assess how many pins are on the connector. You can make more electrical connections if there are more pins. But, more pins can also mean a larger connector footprint, which can have an impact on your board layout.

The pitch of the connector is another important factor. This is the distance between adjacent pins. For high-density applications, a smaller pitch allows for finer pitch connectors. A larger pitch, on the other hand, makes it easier to insert and remove cables from the connector.

It is also a good idea to choose the connector’s mating type. There are two main options: surface-mount (SMT), and through-hole. SMT connectors can be used for densely packed circuit boards because they are smaller and easier to use. THT connectors, on the other hand, offer greater mechanical support and are more easy to use during prototyping or assembly.

Why would you need a connector for a PCB?

You’re familiar with the delicate nature of printed circuit boards (PCBs) if you have ever used them. You don’t want the PCB to get damaged during assembly. This is where PCB connectors are useful.

These connectors protect your PCB during assembly. They keep your PCB in place and prevent it from moving around, causing shorts or other problems.

There are many types of PCB connectors available. You will need to select the one that is right for you. No matter what type you choose, PCB connectors will be essential for any printed circuit board assembly.


You can see that PCB connectors have many uses. These connectors can be used to connect two boards, or to establish a reliable connection between your computer and another device. It’s worth doing some research to determine which connector is best for your project. Don’t be afraid to ask for assistance if you aren’t sure which one to choose.
