PCBTok is Your Remarkable Heavy Copper PCB Fabricator

Heavy copper PCB is commonly used in military and aerospace applications. It is now also finding its way into industrial applications. In power supply and converter applications, their performance and durability are critical.

Here are a few advantages of using heavy copper PCB. All of these benefits make heavy copper PCB an excellent choice for a wide range of industrial applications. You may be wondering why heavy copper is used.

The high copper weight provides a dependable wiring platform and is an ideal substrate for through-hole circuitry. To achieve a thicker copper layer, this material can be fabricated using a variety of plating and etching techniques.

These layers are then plated onto the board’s sidewalls and holes to add thickness. This strengthens the circuit and qualifies it for high current and power applications.

Heavy copper boards’ increased heat resistance can result in lower power loss and heat generation. Another advantage is the thickness of the board surface. The thicker copper surface improves heat conduction and dissipation, contributing to the safety of electronic devices.

Heat sinks that are directly plated onto the board surface are also included with heavy copper boards. This is a great feature for a small board.

Benefits of Heavy Copper PCB

PCBs made of heavy copper are thicker than standard boards. Heavy copper PCBs are typically two ounces thick and contain 75 micrometers of copper. When the copper fill levels are low, these boards are prone to delamination.

Typically, the final thickness is 0.25mm thicker than the initial thickness. It is difficult to incorporate a heavy copper PCB into your circuit design, but it is possible to achieve high-quality results.

Heavy copper PCB design and production necessitate several complex processes, including multiple layers and etching. Copper foil sheets are used as the foundation for circuit layers, and copper plates are then plated through the holes and planes. The entire circuit is then laminated onto an epoxy-based substrate.

Heavy copper PCBs, as the name implies, necessitate a highly specialized pressing process. The copper layers are etched during this process to provide a variety of features that help improve circuit performance. They are also designed with empty areas in the pattern, and the edges have a single air guide groove to aid in the flow of solder paste and adhesive.

They are made in a different way than regular copper boards. The heavy copper-plated vias transfer the most heat to the external heat sink.

Its high thermal capacity makes them suitable for demanding applications such as solar panels and welding equipment. The heavy copper plated vias ensure exceptional dependability and performance. You can find a heavy copper PCB manufacturer who can provide you with a variety of solutions.

The Heavy copper circuit plate is made of thicker copper and can accommodate high-current and control circuits. Heavy copper’s weight makes it a dependable wiring platform and an appropriate substrate for through-hole circuits. It also allows for the creation of smaller footprints and a lower layer count.

A heavy copper PCB, PCBTok can reach 100 oz for the boards. If you have the Gerber files, please send them to us.

The copper thickness of the standard board is Hoz or 1oz, and the heavy copper is 2oz and more than 2oz.

Another significant distinction between standard and heavy copper PCBs is the substrate material. Thicker substrate materials are required for heavy copper boards. Thick boards are more resistant to heat and can withstand higher temperatures than standard PCBs.

Difference Between Standard and Heavy Copper PCBs

Heavy copper PCBs can also have different copper weights in the same circuit layers. As a result, they are better suited for applications requiring thermal stability. This also aids in their size reduction.

Remember that thick copper-clad laminated board material will necessitate additional etching and plating techniques when designing a heavy copper circuit.

Heavy copper circuit boards were traditionally made by etching thick copper-clad laminated board material, which resulted in unacceptably uneven sidewalls and excessive undercutting. The process is now combined with etching and plating to produce a high-quality PCB with straight edges and good margins using advanced plating technology.

If you’re looking for a heavy copper PCB manufacturer, choose one specializing in heavy copper circuit boards. While this may appear to be a difficult task, it can save you significant time and money.

Here are a few things to think about before deciding on a manufacturer. You should be familiar with their facilities and their capabilities. Knowing where they are can significantly impact their efficiency and cost-effectiveness. Having multiple facilities provides you with more options and can reduce shipping time and costs.

The thickness of the copper is also an essential factor to consider. Heavy copper PCBs contain far more copper than standard printed circuit boards. Furthermore, because the components are burnt, they are more prone to faults. It’s critical to understand what you’re getting from a heavy copper PCB manufacturer so you can be confident you’re getting high-quality components.

For example, if your PCB is carrying a high current, the manufacturer’s copper should be thicker. This is because a PCB made of heavy copper has wider traces and a higher current rating.

When selecting a heavy copper circuit board manufacturer, ensure the company has the capabilities. You will send one trial project to test it and then decide whether you will choose it or not.
