Circuit Board Pin Connectors
Circuit board pin connectors are tiny metal components used to connect electronic parts to PCBs. They come in different shapes and sizes and are often used in electronic devices like computers, graphics cards, and power supplies. Pin connectors have metal pins inserted into holes on the PCB to make a secure electrical connection with the copper traces.
Types of Circuit Board Pin Connectors
Single-row Pin Connectors
These are small connectors with a single row of pins that connect electronic components to a PCB. They are easy to use and are commonly found in computer hardware.
Dual-row Pin Connectors
These have two rows of pins stacked on top of each other, allowing for more connections in a smaller space. They are commonly used in high-density applications where space is limited.
Box Header Pin Connectors
These have a rectangular shape and are used to connect cables or wires to a PCB. They are commonly found in power supplies and other high-current applications.
Shrouded Pin Connectors
These are similar to single-row or dual-row pin connectors but with a protective shroud or cover around the pins to prevent accidental contact or damage. Consumer electronics are among their everyday applications.
Surface Mount Pin Connectors
These are designed to be mounted directly onto the surface of a PCB using solder paste and a reflow oven. They are commonly used in applications with limited space requiring high reliability.
Through-hole Pin Connectors
After being inserted into the holes on the PCB, these components are soldered firmly in place, making them popular for applications that require robust mechanical performance.
Card Edge Pin Connectors
With their specifically designed pins that slot into a card edge on a PCB, these components find frequent use in computer hardware, particularly in expansion cards.
Board-to-board Pin Connectors
In applications that require a connection between multiple PCBs, such as in large electronic systems, these components come in handy as they connect two PCBs perpendicular to each other.

Pin connectors have a low profile, which means they take up minimal space on the circuit board. It allows more components to be added to the circuit board without increasing size. It is critical in applications with limited space.
With a modular design, they can be easily replaced or upgraded without replacing the entire circuit board. This modularity ensures the electronic device can be easily maintained and upgraded as needed, reducing the cost.
Pin connectors can be packed densely on a circuit board, allowing for more connections to be made in a smaller area. It ensures the electronic device remains compact and efficient, even as more components are added to the circuit board.
Choosing a Perfect Circuit Board Pin Connector
Choosing a suitable circuit board pin connector involves several considerations that will ensure the connector meets the specific requirements of your application.
Determine the number of pins required for your application. Pin counts can range from a few pins to hundreds of pins.
The pitch is the distance between each pin on the connector. Make sure that the pitch matches the spacing of the holes on your circuit board.
There are various mounting styles, including through-hole, surface-mount, and board-to-board. Choose the most suitable mounting for your application.
Pin connectors may have a vertical orientation, a right angle, or a horizontal orientation. Consider the space available on your circuit board and the direction in which the connector needs to face.
It’s crucial to select a pin connector with a current rating that matches the current requirements of your circuit.
To ensure the proper functioning of the circuit, choose a pin connector with a voltage rating that matches the voltage requirements of your printed circuit board.
Consider the type of signals that will be transmitted through the connector. Some connectors are designed for high-speed data transmission, while others are designed for power or audio signals.
There may be more factors to consider depending on the specific application requirements. For example, considerations such as temperature range, vibration and shock resistance, and environmental factors such as moisture and dust may also be vital. Carefully evaluate all relevant factors to ensure the pin connector meets the specific requirements of your application.
