Interconnects are components that provide electrical connections between various parts of an electronic system. They are essential for the proper functioning of electronic devices, and without them, it would be impossible to create complex circuits. There are various types of interconnects available, including vertical mount, horizontal mount, board-to-board, and cable-to-board interconnects. In this blog post, we will focus on horizontal mount interconnects, also known as right-angle interconnects, and their importance in electronic devices.

Definition and Types of Interconnects

Before we dive into horizontal mount interconnects, let’s first define what interconnects are and explore the different types available.

Definition of Interconnects

Interconnects are components that provide electrical connections between various parts of an electronic system. They allow for the transfer of data and power between components, which is essential for the proper functioning of the system. Interconnects can be as simple as wires or as complex as multi-pin connectors.

Types of Interconnects

There are several types of interconnects, including:

1. Vertical mount interconnects – these interconnects are perpendicular to the circuit board and are typically used to connect components on different levels of the board.
2. Horizontal mount interconnects – also known as right-angle interconnects, these components are parallel to the circuit board and are used to connect components that are located next to each other.
3. Board-to-board interconnects – these interconnects are used to connect two circuit boards together.
4. Cable-to-board interconnects – these interconnects are used to connect a cable to a circuit board.

Advantages of Horizontal Mount Interconnects

Horizontal mount interconnects offer several advantages over other types of interconnects, including:

Space-saving design

Horizontal mount interconnects take up less space on a circuit board than other types of interconnects. This makes them ideal for use in compact electronic devices such as smartphones, laptops, and wearables.

Increased reliability

Horizontal mount interconnects are designed to withstand the stresses of repeated connections and disconnections. This makes them more reliable than other types of interconnects and reduces the likelihood of failure.

Easier assembly and maintenance

Horizontal mount interconnects are easier to assemble and maintain than other types of interconnects. This is because they are typically mounted on the surface of the circuit board and can be accessed easily.

Enhanced performance

Horizontal mount interconnects offer enhanced performance over other types of interconnects. This is because they have shorter signal paths, which reduces the chances of signal degradation.

Applications of Horizontal Mount Interconnects

Horizontal mount interconnects are used in a wide range of electronic devices, including:

Consumer electronics

Horizontal mount interconnects are used in a range of consumer electronics such as smartphones, tablets, and laptops. These devices require a large number of interconnects to connect the various components together.

Industrial equipment

Horizontal mount interconnects are also used in industrial equipment such as robots, sensors, and control systems. These devices require reliable and robust interconnects to ensure proper operation.

Medical devices

Horizontal mount interconnects are used in medical devices such as diagnostic equipment and monitoring systems. These devices require high-quality interconnects that can withstand harsh environments.

Automotive industry

Horizontal mount interconnects are used in the automotive industry to connect various components in a vehicle. They are designed to withstand the harsh conditions of the automotive environment and provide reliable connections.

Horizontal Mount Interconnects in Detail

Now that we’ve covered the basics of horizontal mount interconnects, let’s dive into more detail.

Description of the Design

Horizontal mount interconnects are designed to be mounted on the surface of a circuit board at a right angle. They typically have a rectangular shape with two rows of pins or contacts that are arranged perpendicular to each other. One row of pins is used to connect to the circuit board, while the other row is used to connect to other components. This design allows for a compact form factor while still providing a large number of connections.

Materials Used in Manufacturing

Horizontal mount interconnects are typically made from materials such as copper, brass, or phosphor bronze for the contacts, and plastic for the housing. The contacts are often gold-plated to provide a reliable connection and prevent corrosion. The plastic housing is designed to withstand high temperatures and provide insulation between the contacts.

Technical Specifications

Horizontal mount interconnects are available in a range of technical specifications, including pitch, number of contacts, and current rating. Pitch refers to the distance between adjacent pins or contacts and is typically measured in millimeters. The number of contacts can range from a few to several hundred, depending on the application. The current rating refers to the maximum amount of current that can flow through the interconnect without causing damage.

Comparison with Other Types of Interconnects

Horizontal mount interconnects offer several advantages over other types of interconnects. For example, they take up less space than vertical mount interconnects, and they are more reliable than cable-to-board interconnects. However, they may not be suitable for all applications. For example, board-to-board interconnects may be more suitable for connecting two circuit boards together.

Factors to Consider When Choosing Horizontal Mount Interconnects

When choosing horizontal mount interconnects for a specific application, there are several factors to consider, including:

Space Requirements

Horizontal mount interconnects are ideal for applications where space is limited. However, it’s important to ensure that the interconnects can still provide the necessary connections without overcrowding the circuit board.

Signal Integrity

Horizontal mount interconnects can affect signal integrity, particularly if they are not properly designed or manufactured. It’s important to choose interconnects that have a low crosstalk and high signal-to-noise ratio to ensure proper operation.

Environmental Factors

Environmental factors such as temperature, humidity, and vibration can affect the performance of horizontal mount interconnects. It’s important to choose interconnects that are designed to withstand the specific environmental conditions of the application.

Cost

Horizontal mount interconnects vary in cost depending on their technical specifications and materials used in manufacturing. It’s important to choose interconnects that provide the necessary performance at a reasonable cost.

Conclusion

Horizontal mount interconnects are an essential component of many electronic devices. They offer several advantages over other types of interconnects, including space-saving design, increased reliability, easier assembly and maintenance, and enhanced performance. Horizontal mount interconnects are used in a wide range of applications, including consumer electronics, industrial equipment, medical devices, and the automotive industry. When choosing horizontal mount interconnects for a specific application, it’s important to consider factors such as space requirements, signal integrity, environmental factors, and cost. With careful consideration, horizontal mount interconnects can provide reliable and robust connections that are essential for the proper functioning of electronic devices.
