Thick copper PCB has large thickness over standard copper PCB, the additional copper PCB thickness lends the board to withstand a large value current, and achieve better thermal conductivity than standard copper PCB. Meanwhile, the heavy copper PCB has better mechanical strength at connector sites, enable to create a smaller electronic device. The heavy copper PCB has a great demand in computer, automotive, military, and industrial controls, widely used for power supplies, power converters, welding equipment, overload relays, etc. If you are looking for durable quality thick copper PCB products at competitive price, don’t hesitate to contact us.
Copper plays a huge role when it comes to PCB boards. There are certain tasks that simply cannot be performed unless the thickness of the copper used in the PCB boards is high. Otherwise, it would be impossible for the electronic products to provide the results that you are looking for.
The copper-clad laminate thickness is something that you cannot afford to ignore. This is why getting a thick copper PCB board is crucial. It has a thickness of around 1.6 mm which is greater than most PCB boards in the market. Therefore, it would provide tolerance. As copper-clad laminate is an essential raw material, you need to get it right. The right amount of copper-clad laminate, substrate, and copper foil make all the difference. Then, the product would be impregnated with resin or hot pressed for the desired results.
What Is Thick Copper PCB Board?
For those of you that do not know, a thick copper PCB board does just what its name tells you. It is designed for performing only heavy-duty tasks. It is not like a thin PCB board which is known for its versatility. It provides greater power supply for performing difficult tasks. If you need a PCB board to conduct different tasks that other PCB boards fail to perform, it has got you covered.
Heavy Copper PCB means Thick copper PCB refers to a printed circuit board (PCB) that uses significantly thicker copper layers for its conductive traces, planes, and plated holes compared to standard PCBs. Here’s a detailed breakdown:
Key Characteristics
Copper Weight:
Standard PCBs: Typically use 1 oz/ft² (35 µm) to 3 oz/ft² (105 µm) copper.
Heavy Copper PCBs: Start at ≥4 oz/ft² (140 µm) and can extend to >20 oz/ft² (700 µm) or even higher for extreme applications.
Heavy copper PCB Manufacturing Process:
Requires specialized techniques like differential etching (multiple etch/plating steps) or extended plating times to achieve thick copper layers without undercutting traces.
Substrates must withstand high temperatures during soldering due to copper’s thermal mass.
Advantages of Thick Copper PCB Board
✅ High Current Capacity:
Thicker copper = lower electrical resistance → carries more current without overheating (e.g., power supplies, motor controllers).
✅ Enhanced Thermal Management:
Copper conducts heat efficiently → dissipates heat away from hotspots (e.g., power semiconductors, LEDs).
✅ Increased Mechanical Strength:
Robust connectors/pads withstand repeated plugging or high-vibration environments (e.g., automotive, aerospace).
✅ Space Efficiency:
Replaces bulky busbars/wires → integrates high-power and control circuits on a single board.
✅ Reliability:
Reduces failure risks from thermal cycling (less expansion/contraction stress).
