If you are looking for a thick copper PCB, you have come to the right place. You can find a number of different options to choose from, but not all of them are created equal. In fact, the quality of the board can make all the difference. Here, we’ll examine some of the key factors to keep in mind when deciding whether or not a certain thick copper PCB is right for your needs.

Thick copper PCB

Thick copper PCB is an important technology for high-power applications. These products provide better thermal management, reduced footprint, and improved efficiency.

The advanced development of the electronics industry has contributed to the rising demand for thick copper PCBs. They provide many benefits to the users, including low cost, good performance, and high reliability.

The thick copper PCBs are also used in power modules. They can combine complicated switches in limited space. Moreover, they reduce the time and cost of wiring. This improves productivity and reliability of final products.

In addition, the thick copper PCBs have the capability to minimize the working noise. Compared to standard PCBs, they have improved thermal management and better heat dissipation.

However, there are some disadvantages of the thick copper PCB. For instance, the thick PCBs are heavier. Therefore, they will not perform well in rugged environments. Another problem is that they may be expensive.

Thicker copper layers enable the supper heavy copper pcb creation of large PCB-cross-sections for high-current loads. It also allows fine layout structures on the outer layers.

Thick copper PCBs can be produced in a variety of styles, from double-sided to multilayer. However, the thickness of the open area should be carefully considered. If the open area is too thin, the board will be difficult to use. Also, excessive temperature can negatively affect the circuit board’s performance.

Hence, it is recommended to purchase a product that meets industry quality standards. These standards are global and ensure the safety of the product and the manufacturing process.

The most common thick copper PCB designs are single-sided or multi-layer. Besides, different polarities are available in the package.

The thick copper PCB is manufactured with a special non-toxic passivation protective layer. There are also several buried blind vias for preventing wire channel interference.


Plating supper heavy copper PCB is perfect for high end applications and has many advantages over standard PCBs. In addition to having good current carrying capacity, it is highly durable, and provides excellent heat dissipation. This type of PCB is ideal for defense and military applications, as well as medical devices.

Historically, heavy copper circuit boards were fabricated by etching thick copper clad laminated board material. However, this method caused uneven trace sidewalls and unacceptable undercutting. Consequently, heavy copper PCBs are manufactured with different etching and plating techniques.

Using advanced plating technology, manufacturers are able to combine the processes of plating and etching, resulting in straight sidewalls and negligible undercutting. The result is improved efficiency, productivity, and the reduction of the time required for electroplating.

Copper PCBs are widely used in high-end applications. They are especially useful in defense and automotive applications. Also, they are ideal for industrial controls, welding equipment, and solar panels. Heavy copper PCBs can be manufactured with a variety of dielectric materials to meet customer requirements.

When choosing a copper PCB, the thickness of the copper is a significant factor in determining its strength. If the thickness is too thin, the open area may be unusable. Therefore, it is important to choose a copper thickness that matches the project impedance.

As a rule of thumb, the thickness of the copper on the PCB should be approximately 3oz per square foot. Additionally, the number of layers must also be considered. For multilayer boards with 8 or more layers, the thickness must be at least 1.5 mm.

Whether you need a heavy copper PCB or standard PCB, you should check with the manufacturer for more information on their capabilities and prices. You should also take into account the type of components you want to use on the board.


Heavy copper PCBs are used for high-power and high-voltage devices. They are ideal for medical devices, defense applications, and many other industries. These boards offer multiple features to enhance the circuit’s performance.

These circuits are manufactured with specialized etching and plating techniques. The combination of these processes produces high resolution traces that are flat and straight. This allows for minimal undercut and makes the surface of the board smooth.

Heavy copper PCBs use copper clad laminated boards as their substrate. However, etching this material creates uneven edge lines, which were not acceptable. Fortunately, the industry has improved with new technologies.

Using thick copper in circuits allows for less resistance, which is great for high-power electronics. This reduces the heat of the device and lowers the voltage drop. It also results in more finely defined traces.

To produce a heavy copper PCB, manufacturers use a variety of different processes. Some of these include acidic etching, dry etching, and cupric chloride etching.

Acidic etching is cheaper, but takes a bit longer. During the process, a large amount of copper is removed. In this process, a PCB is immersed in an etch bath, which is heated to an appropriate temperature. As the copper dissolves, it tunnels into the traces.

An anisotropic etching process is more expensive and requires additional equipment. Cupric Chloride etching is more precise and reliable.

Heavy copper PCBs are drilled with a special UC thick copper drill bit. These bits are designed to produce a smooth hole wall. Similarly, the bottom and vertex copper PADs on each supper heavy copper pcb side of the board are designed to be the same size and shape.


Heavy copper PCBs are becoming popular in the electrical industry. They offer numerous benefits over standard PCBs. These include a larger capacity for current, better thermal dissipation, and higher thermal performance.

When it comes to assembling a heavy copper PCB, it is important to work with a qualified manufacturer. The wrong manufacturer can lead to the failure of a project.

Many industries are using heavy copper in boards because of their ability to solve high power and current needs. For example, heavy copper PCBs are used in defense applications, power grid switching systems, high power rectifiers, military applications, and medical devices.

High-current PCBs are capable of supporting hundreds of amps. This means that they can be used for many different functions, including recharging electric vehicles, high-power rectifiers, and power grid switching systems. In addition, they can carry much more heat than standard PCBs.

Compared to standard PCBs, a heavy copper PCB is more expensive. It is also harder to manufacture. During the manufacturing process, the board undergoes a number of special etching procedures and pressing techniques.

There are also special dielectric materials that improve the weather resistance of the board. Lastly, the thickness of the board can vary depending on the type of PCB.

Normally, a standard PCB is manufactured with copper thickness of one ounce or two ounces. However, these thicknesses can be as low as four ounces or as high as 20 ounces. Moreover, thicker layers require more prepregs during lamination.

In order to determine the correct thickness of your PCB, it is important to use a design tool. Your design tool will estimate the weight of your copper and help you calculate the amount of current that you need to transport.
