The Specialized Manufacturing Process for Heavy Copper PCBs
The manufacture of heavy copper PCBs requires specialized processes and equipment. These PCBs are defined as those with copper foil
When fabricating heavy copper PCB or thick copper PCB boards, great expertise is needed to produce the right product. Due to the unique benefits of heavy copper PCB, a lot of power electronics are being produced with this material. As our society advances, the demand for thick copper PCB boards increases. Generally, heavy copper PCB boards can be used to create complex circuits within a constrained space. They are also used because of their heat dissipation and high current abilities.
A heavy copper PCB board is a type of printed circuit board which is known to feature 3 or more ounces of copper on the PCB’s internal and external layers. This type of circuit board is also known as a thick copper PCB or extreme copper PCB. We have a wide range of circuits that feature over 4 or more ounces per square foot of copper known as heavy copper PCB boards. Heavy copper PCB boards are known for their enhanced copper weights. They also have thicker plating materials and the right substrate elements that are featured in the through-holes. This can easily help to transform any weak PCB into a dependable and long-lasting wiring platform. The use of heavy copper conductors in a board can considerably increase the thickness of the PCB. During the circuit design, the thickness of the copper needs to be considered carefully. Extreme copper is a type of copper that features between 20 and 200 ounces of copper for every square foot.
You can rely on engineering properties to help create various possibilities and value with all your products. This is possible due to the various range of benefits that the product feature. One of the core benefits of the heavy copper boards is their tendency to withstand continuous exposure to very high currents, increased temperatures, and frequent thermal cycling. These hazards have the potential to cause damage to a regular PCB in a matter of seconds. Heavy copper boards are known for their high tolerance ability. This is why they can be used in a variety of applications in extreme conditions such as the aerospace and defence industry products. Our heavy copper boards are:
Our heavy copper boards can be fabricated to be used for a variety of purposes. They can be used in such applications as power converters, high-power distribution systems, heat dissipation, planar transformers, etc. Due to the benefits of heavy copper boards, they are used widely in industrial, military, automotive, and computer systems. In addition, heavy copper boards are applied in:
Choosing the right copper thickness for a PCB is an important design decision that can impact the performance and reliability of the board. Here are some factors to consider when selecting the copper thickness for a PCB:
Current carrying capacity: The thickness of the copper layer impacts the current carrying capacity of the PCB. Thicker copper layers can handle higher current levels without overheating or damaging the board.
Thermal management: The thickness of the copper layer also affects the thermal management capabilities of the PCB. Thicker copper layers have better heat dissipation properties and can help dissipate heat more effectively from the components.
Trace width: The thickness of the copper layer is related to the width of the traces on the PCB. Thicker copper layers can support wider traces, which can help reduce resistance and improve current carrying capacity.
Manufacturing capabilities: The thickness of the copper layer may be limited by the manufacturing capabilities of the PCB manufacturer. Thicker copper layers may require specialized manufacturing processes, which can increase the cost and lead time of the PCB.
Cost: The thickness of the copper layer is a factor in the cost of the PCB. Thicker copper layers generally cost more than thinner layers, so the choice of copper thickness should be balanced with the requirements of the application and the available budget.
In general, a copper thickness of 1 oz (35 microns) is sufficient for most low-power applications. For high-power applications, a copper thickness of 2 oz (70 microns) or more may be required. It is recommended to consult with the PCB manufacturer and consider the specific requirements of the application before choosing the copper thickness for a PCB.
Heavy copper PCBs have unique properties that make them suitable for high-power and high-temperature applications. Here are some key performance metrics and testing methods to evaluate heavy copper PCBs:

Heavy copper PCBs are characterized by their thick copper layers, which can range from 3 oz (approximately 105 microns) to 20 oz (approximately 700 microns) or more. The thickness of the copper layer depends on the specific requirements of the application and the current carrying capacity and thermal management needs of the board.
In general, heavy copper PCBs have a minimum copper thickness of 3 oz (105 microns), which is significantly thicker than the standard 1 oz (35 microns) copper thickness used in traditional PCBs. The copper layers in heavy copper PCBs are typically several times thicker than the base material, such as FR-4, used in the PCB.
The copper weight of a PCB refers to the thickness of the copper layer on the board, and it is typically measured in ounces per square foot (oz/ft2) or microns (µm). The copper weight of a PCB determines the current carrying capacity, thermal management, and mechanical strength of the board.
In general, PCB copper weight ranges from 0.5 oz (approximately 17.5 microns) to 6 oz (approximately 210 microns) or more. The most common copper weight for standard PCBs is 1 oz (approximately 35 microns) per square foot. However, for high-power and high-temperature applications, thicker copper weights may be required to handle the increased current levels and dissipate heat effectively.
1 oz of copper PCB refers to the thickness of the copper layer on the board, which is approximately 35 microns or 1.4 mils. This is the standard copper weight used in most PCBs.
The total thickness of a typical PCB can range from 0.2 mm to 3 mm or more, depending on the specific design and requirements.
