Heavy copper printed circuit boards are the latest trend in PCB industry. These PCBs are used in various electrical circuits due to several benefits they offer. Although these PCBs are expensive to produce, they are still in high demand. Why? Read the post to know more about them.
There is no specific definition for a heavy copper PCB. However, the term is more commonly used for PCBs featuring 3 ounces of copper in the internal and external layers. This term is also applied to any circuit with copper thickness more than 4 Oz/ft2. The term extreme heavy copper PCB refers to PCBs with 20 Oz/ ft2 to, which has 200 oz. per ft2 copper deposition on its internal and external layers.
The copper weight combined with an appropriate substrate and thicker plating in the through-hole circuit makes these PCBs a reliable wiring platform. These boards are manufactured through a variety of etching and plating techniques. The goal is always adding copper thickness via plated holes and sidewalls.
The following benefits heavy copper PCBs make them ideal for various electrical applications:
Heavy copper PCBs are used in the following applications:
Reliable performance and excellent thermal management is the main driver behind the demand of copper PCBs. Today, circuits are built to pass heavy currents, which means high heat is produced. However, heavy copper PCBs will help dissipate heat produced efficiently, thereby ensuring optimum performance of the circuit. If you are still unsure about the benefits of copper PCBs in your electrical applications, you can always approach an electrical expert or a reliable heavy copper PCB manufacturer like Twisted Traces. The company provides heavy duty copper PCBs for all industrial applications.
