Printed Circuit Board connector, also known as PCB connector, is a fundamental part of any electronic device; they provide the connection between a circuit board and its components. From consumer appliances to automobile engineering and aerospace technology - these versatile elements can be found in an array of industries across the globe. Their reliable performance makes them integral assets for ensuring efficient functioning within our technological world!
PCB connectors are essential to ensure a solid, dependable connection between two or more circuits. Whether it's for transmitting power, data or signals from one device to another - these connectors guarantee an effective transfer of information in any environment. Available in numerous sizes and forms that can cater to all your needs, the possibilities for customization with PCB connectors are practically endless!
As you look for the ideal PCB connector, a crucial aspect to keep in mind is the pitch - or spacing between its pins and contacts. This interval may differ depending on both size and type of connector, so it's essential to consider this when factoring in your board design's overall dimensions. Other important factors to consider when selecting a PCB connector include the termination method, materials and coatings, and connector features such as locking mechanisms and keying.
Depending on the usage and conditions, PCB connectors can be securely attached by using either a through-hole or surface-mount technology (SMT) process. Through-hole mounting requires inserting the connector pins into drilled holes in the circuit board while SMT necessitates attaching them to its surface directly.
When selecting the best PCB connector for your application, there are a variety of options available. From custom-made connectors to common types like FPC/FFC and D-Subminiature, you will find one that meets precisely what you require. Here's a list of some of the most popular varieties:

When selecting a PCB connector, the pitch and size are essential considerations. Pitch is the distance between contacts while size accounts for its total dimensions such as width, length, and height. These parameters can affect not only your circuit board's design. But also the electrical/mechanical efficiency of the system itself - so make sure to take them into account!
Connectors come with various pitches, ranging from something as small as 1mm to more than 5mm for larger connectors. A minuscule pitch can offer a higher pin count in one space but may be difficult and time-consuming to manufacture. On the other hand, a larger pitch will streamline production and mating yet limit the number of pins allowed within an assigned area.
The size of the connector depends on a variety of factors, including space available on the circuit board and its desired electrical and mechanical performance. While some connectors are designed to be small yet powerful, others may need to be bigger and stronger for use in tougher conditions.
In order to choose the right connector for your application, it is important to take into account its pitch and size. The chosen product should not only fit in the available space on the printed circuit board. But also be capable of providing reliable electrical as well as mechanical performance. Moreover, it must be compatible with other connectors or devices so that a safe connection is established between them.
When choosing a PCB connector, apart from the pitch and size of the device, there are several other essential elements to mull over. Here's a list of some key features you should keep in mind:
