PCB (Printed Circuit Board) headers, also known as PCB pins, are electrical connectors designed to join various connections to printed circuit boards employing a single block. Basically, these are equipped with a single side to be soldered, or surface mounted onto boards along with the alternate side for connections. For making a secure connection/unit, headers’ pins are surrounded by a plastic shroud and provide a secure locking that prevents pins from bending. In addition, the integrated PCB receptacle contacts come in a varied line style to fit square, round, or rectangular component leads, respectively.
Why should I opt for PCB headers?
These exquisite and versatile devices offer reliable connections to PCBs and are easy to use. They are easily soldered onto boards where each pin is ideal for a variety of things like data or power. Furthermore, they are an excellent choice for beginners learning electronics due to their simple, easy-to-understand designs. In addition, they are supplied with various learning boards, accessories, and kits that are ideal for learning various projects, such as Raspberry Pi and Arduino.
Types of PCB headers:
Printed circuit board headers are available in shrouded and non-shrouded pin header types. Each type features various characteristics with pros and cons. Shrouded connectors are reliable, robust, and avoid short circuits; however, they occupy more PCB space. On the other hand, pin headers feature a wide range of applications and are designed to be easy to work with. They come in the following types.
These headers feature a circular cross-section designed to fit precisely into round printed circuit board holes. They are widely suited for their precise electrical connections. In addition, they are highly durable with a long-lasting lifespan.
- Single or double-row pin headers
They are the most commonly used PCB pin headers constructed from folded sheet metal. They come in male and female matching versions with a square cross-section.
As the name suggests, these connectors come in a great range of angles, such as straight (90°) and horizontal (180°). They are ideal where extra space or reduced strain is required on a cable or board, either horizontally or vertically.
What are the uses of PCB headers?
These PCB pins are found in various applications, such as:
- Circuit modules (such as LCD circuit modules and XBee circuit modules)
- Evaluating PCB boards and other essential PCB types
- Used in conjunction with jumper wires to create semi-permanent input devices
- Computer’s power supply system and motherboard.
