Heavy Copper PCB
Heavy copper pcbs can handle much higher current levels than standard PCBs. They are in demand for high power applications such as automotive, military and industrial control.
Achieving a successful fabrication of heavy copper pcbs requires a close collaboration between designer and fabricator. The key considerations include stackups and resin filling capability.
1. High current conductivity
If you’re using a circuit board that will require a high current, it’s crucial to use the best quality PCB. If you choose a poor quality PCB, it will not be able to pass the heavy current and may damage your product. This is why it’s important to look for a company that offers heavy copper pcb.
Heavy copper PCBs are designed to accommodate higher critical current densities than standard PCBs. They also feature thicker copper plating in the plated through holes. These features make them more reliable and help to reduce failures due to thermal stress.
When a PCB passes a high amount of current, it will generate heat. The deposited heat will then dissipate through the copper traces and into an external heat sink. This will ensure that the board operates at optimal performance and can withstand extreme temperatures. However, a designer should still consult with the fabricator to discuss manufacturing tolerances and capabilities before finalizing the design. They should also consider the substrate material, which must be able to withstand a high current load without cracking or layer separation.
2. High thermal conductivity
Heavy copper PCB is a type of printed circuit board that has a copper layer that is thicker than the normal ones. This is achieved by using an inner layer of prepreg with a different outer layer.
The main advantage of this type of PCB is that it can withstand high currents and has good thermal conductivity. This is important as excessive heat can damage the performance and life of the circuit board.
Moreover, heavy copper PCBs have increased endurance to thermal strain. This is an important feature because standard copper PCBs have a limited endurance to this. In addition, heavy copper PCBs are often more expensive than standard ones.
It is also important to note that heavy copper PCBs require a careful design of the copper layer and tracks on the board. These need to be positioned heavy copper pcb properly to reduce the stress of the copper. It is also necessary to ensure that there are no gaps between the traces. This will help to reduce the amount of resin needed in lamination. This will prevent delamination and other problems.
3. High temperature resistance
Heavy copper pcb has high temperature resistance, which makes it ideal for use in various industrial applications. It can withstand extreme conditions, including high temperatures and special environments. This means it can be used in many different kinds of electronic devices.
The temperature resistance of copper is proportional to the current it carries. PCB designers gauge the amount of current required for a design and then determine the thickness of copper needed to accommodate the load. This is done by using a trace width technique that considers three different factors: current, temperature increment, and the width of the trace.
This method allows designers to increase the copper weight of via sidewalls and plated holes, which can reduce layer numbers and footprints. It also helps to improve thermal management by reducing board heat. Excessive heat can damage circuits, so it’s important to match them with appropriate heat sinks and add copper plating to through holes. This will help to disperse heat and ensure that the circuit boards can function properly.
4. High tensile strength
Heavy copper PCBs are more durable than standard circuit boards, which makes them ideal for devices that require a lot of power and current. They can withstand repeated exposure to excessive current and high temperatures, which would otherwise destroy regular PCBs.
This means that PCB designers should carefully gauge the amount of current they will need and choose a suitable copper thickness and width. This Heavy Copper PCB Supplier will help them avoid overheating and shorting out the circuit board. To make this process easier, designers can use a trace width calculator to determine the required copper thickness and current capacity.
Using thick copper also allows for better mechanical strength in the copper sidewalls and plated-through holes. This is particularly important in high-current applications, such as those used in motors and engines. In addition, heavy copper is resistant to corrosion and other environmental factors.
To maximize the performance of your electronics, consider using a double-sided, multilayer circuit board made with thick copper. This PCB has many advantages over standard PCBs, including a higher tolerance capacity and a more durable design.
5. High density
PCBs use a variety of different metals to provide the electrical current needed for them to function. These metals are plated onto the copper traces to provide the necessary conductivity. A standard PCB may contain 3 oz of copper in the outer and internal layers, while a heavy or extreme copper PCB contains 10 oz of copper per square foot.
This increase in copper thickness allows the circuit board to carry higher current outputs and optimize thermal management. It also helps create more complex switches and other functions within a smaller area. A heavy copper pcb is also able to withstand higher temperatures and is more durable than a standard PCB.
This type of PCB requires a special etching process and has some technical thresholds that must be met. It is therefore important for designers to work closely with their fabricators during the design process. This will help ensure that all aspects of the board are fabricated to specification. It will also help to ensure that any potential issues are addressed early in the design process.
