Heavy Copper Printed Circuit Board Description:
Heavy copper technology is one of the solutions to reach the needs of modern power electronics, and heavy copper printed circuit boards are the latest trend in PCB industry. Heavy copper PCBs are highly used for high power and current applications in power supplies, welding equipment, electrical power distribution, power converters, solar panel devices, medical, automotive, aviation and etc. because the heavy copper layers are helpful for controlling the thermal dissipation and running high power and current. Our heavy copper PCB manufacturing service covers single-sided, double-sided and multilayer PCBs.
Heavy Copper PCB, also called as Thick Copper PCB, or High Copper PCB. The thickness of copper on a PCB is often discussed in terms of “weight” in ounces. A 5 oz (ounce) copper layer would mean that it is 175μm (i.e. 7mils) thick. The measurement refers to 1 ounce (28.35g) of copper being spread to cover 1 square foot (929cm2) of PCB area evenly. What’s Heavy Copper PCB? There is no a standard definition. But when the internal or external layers of copper weight that are 2oz (ounces), 3oz or more per square foot, we treat them as heavy copper boards.
What Are the Advantages of using Heavy Copper PCB?
- Plating and etching combination making straight sidewalls and negligible undercut.
- Increasing copper thickness in PTH and via sidewalls.
- Increasing range of current conductivity.
- Potential smaller board size from layering.
- Increasing strength at connector sites.
- Transferring heat to external heatsink.
- Increasing mechanical strength at connector sites and in PTH holes./li>
- Increasing the endurance to thermal strains.
- Increasing on-board high-power-density planar transformers.
