The Application Areas of Aluminum PCB And Different Types of Alu

Printed circuit boards (PCBs) can be made from various metals. These special PCBs are known as a metal core printed circuit boards (MCPCBS). The metal changes on the basis of the application. Aluminum PCBs are one of the popular types of metal MCPCBS, which find use in many modern day applications. These PCBs feature metal-based and copper-clad laminates. Such a construction makes the circuit board an excellent electrical insulator and thermal conductor. It also helps the PCB in delivering high performance. Here we will discuss in detail what aluminum printed circuit boards are. Also, covered in the post is the manufacturing process of these PCBs, as well as the applications of these circuit boards.

What are The Application Areas of Aluminum PCBs?

Aluminum printed circuit boards are among the most widely and commonly used circuit boards? They find their use in a vast variety of applications like these:

a. Signal Beacons

b. Surgical Lighting Tools

c. Power Transmission Systems

d. High-power Scanners

e. Automotive Dashboards

f. Interior Lighting

g. Power Converters

h. Medical Operating Theatre Lighting

i. Landscape Lighting

j. Tail Light Assemblies

This was the basic information to help you understand what exactly are aluminum circuit boards and their applications. Now let’s discuss the different types of aluminum PCBs and their benefits

What are the Different Types of Aluminum PCBs?

As said earlier, selecting the type of aluminum circuit board depends largely on the application for which it is used. There are three main types of aluminum PCBs as follows:

1. Through-hole Aluminum PCBs---In the through-hole aluminum circuit boards, the aluminum is pre-drilled. After that, a dielectric is back-filled into the hole.

2. Flexible Aluminum PCBs---In these PCBs, flexible dielectrics are used, which provide a high level of flexibility, thermal conductivity, and electrical insulation. When these dielectrics are used with aluminum material, the product thus formed is highly flexible and can be formed in different shapes. This helps eliminate costly connectors, and fixtures.

3. Hybrid Aluminum PCBs---These types of aluminum PCBs are generally used in RF applications, and are known to provide a better thermal performance when used in a standard FR4 product.
