PCB pins, sometimes also referred to as connector pins or simply pins, are metallic parts that form the connecting points on a printed circuit board. They physically interface between the PCB and other electronic components or external devices. These pins normally come with sockets, headers, connectors, or are directly soldered onto the board for electrical interconnections.<h3>Types of PCB Pins</h3>They are available in a variety of sizes, shapes, and materials, depending on the occasion. Here are some examples of typical PCB pins: Through-Hole Pins: Through-hole pins are intended to be placed into drilled holes on a PCB and soldered on the other side. They offer strong mechanical support and are commonly utilized in circumstances requiring endurance.Surface-Mount Pins: Unlike through-hole pins, surface-mount pins are soldered to the PCB's surface. They are ideal for situations where space is restricted since they do not necessitate boring holes in the board.Straight Pins: These pins have a straightforward design and are used for direct, in-line connections. They're typical in applications where wiring must go straight from one component to another.Bent Pins: These pins are bent at various angles to accommodate specific design requirements or to fit into compact spaces.Gold-Plated Pins: Because of its excellent conductivity and resistance to oxidant corrosion, gold-plated pins are commonly used in high-reliability applications.<img src="https://img.pcbx.com/dev/file/image/article/20241128/84f7bf9504824628aa91b452fb5efe7f.jpg" alt="PCB Pins-PCBX" data-href="" style="width: 100%;"/><h3>Applications of PCB Pins</h3>PCB pins are used in a broad range of applications, including consumer electronics and industrial machinery.

A PCB header is a kind of electrical connector that is mounted and soldered onto the surface of a PCB, allowing the connection of various external components through a single block. The design of the PCB headers usually contains rows of pins that may either be shrouded for increased durability or unshrouded for more simple applications. Shrouded connectors are designed with a protective plastic housing, which prevents pin bending and ensures secure connections. This makes them particularly robust against electrical shorts but requires more PCB space.PCB headers provide an easy way of making electrical connections on a PCB by consolidating several wires into one block of connection. Each of the pins within the header can serve various functions, such as carrying power or data. These are important not only for professional practice but also in educational aspects whereby they introduce learners to the basics of electronics by making wire-to-board connections both in kits and single-board computers.<h3>Types of PCB Headers</h3>There are several different types of PCB headers based on the unique configurations and specific applications: Pin Headers: There are one and two rows; amongst the most common connectors. It has both male and female versions. As a norm, they are mounted on the breadboards with compatibility at 2.54mm pitches, which is essentially a default for connecting Arduino Shields and Jumper Wires.Angled Connectors: These connectors have pins at some angles, typically 90° or 180°. The primary functions of these angled connectors are to alleviate cable strain and utilize the board space fully.Machine-Pin Headers: Have a round cross-sectional area that provides good electrical contact and durability. Due to the longevity of the machine-pin header, many high-reliability applications involve this header, but at higher costs.<img src="https://img.pcbx.com/dev/file/image/article/20241127/6929a6d660aa4f3ea222150066488fa8.jpg" alt="PCB Header-PCBX" data-href="" style="width: 100%;"/><h3>Basics of Connectors</h3>The understanding of PCB header connectors rests on knowledge of the following important aspects in their construction and application:Gender: Describes whether the connector is male (plugs into) or female (is plugged into).Polarity: A design to ensure that connectors fit only in one orientation to prevent installation mistakes; it is also known as polarized or keyed.Contact and Pitch: A contact is the metallic end that establishes electrical connections, while pitch is the spacing between these connections.Mating Cycle: This refers to a connector's life in terms of the number of connected and disconnected cycles it can withstand.Strain Relief: Provides protection against mechanical stress of electrical connections for stable connection.&lt;button class="center btn-lg" data-href="/order/manufacturing/pcb"&gt;Get an Instant Quote for PCB Fabrication & PCB Assembly&lt;/button&gt;<h3>Applications of PCB Headers</h3>PCB headers are utilized in a number of different applications, including but not limited to:LCD and XBee Modules: Used in establishing safe connections for types of modules.Evaluation Boards: Finds its application in important testing and development of new circuits and systems.Computer Power Supplies: Integral for connecting EEPROMs and floppy drives among others to the motherboard.Motherboards: Ensure the computer system works as expected by providing interaction between different circuit boards.<h3>Electrical Specifications</h3>The typical electrical specifications of PCB headers are:3 A of continuous current rating5000 MΩ of minimum insulation resistanceOperation temperature range: - 65 to +125 Deg Celsius.<img src="https://img.pcbx.com/dev/file/image/article/20241127/577586b8a96c4febbbe2a750fd5b4f6e.jpg" alt="PCB Header-PCBX" data-href="" style="width: 100%;"/>The PCB header is an essential component that can greatly enhance the connectivity and functionality of electronic boards.
