HEAVY COPPER PCB
What is a Heavy Copper PCB?
A Heavy Copper PCB is a printed circuit board designed to handle higher current loads and better thermal management due to its thicker copper layers. These boards are ideal for power electronics and applications where high current or enhanced heat dissipation is required.
Heavy Copper PCBs, also known as Thick Copper PCBs, have garnered significant attention in recent years due to their robust performance and durability. These PCBs feature copper thicknesses ranging from 3 oz/ft² to 20 oz/ft², substantially more than standard PCBs, which typically have copper thicknesses of around 1 oz/ft². This increased copper content lends these boards unique characteristics that are highly beneficial in demanding applications.
Advantages of Heavy Copper PCBs​
- High Current Carrying Capacity
- The thick copper layers enable the board to carry higher current loads without overheating, making it suitable for high-power applications.
- Enhanced Thermal Management
- Improved heat dissipation helps in maintaining optimal performance and reliability, particularly in environments with high thermal stress.
- Improved Mechanical Strength
- The increased thickness of the copper layers provides greater mechanical strength, ensuring durability and resistance to physical damage.
