Is that 3 OZ Copper PCB?

A 3 OZ Copper PCB is a type of “”Heavy copper pcb ‘ Which has a thickness of 3 ounces of copper per square foot, significantly thicker than PCB 1 ounce (35 μm) standard. This design is ideal for high power applications, such as power supplies, automotive electronics, and industrial equipment, where it can handle higher current loads, eliminate more effective heat, and increase mechanical resistance. Increasing the thickness of copper also reduces resistance and improves thermal management, making it a reliable choice for demanding the environment.

How thick 3 ounces of copper on the PCB?

3 ounces of copper on the PCB measuring Kira -Kira 105 micrometers (Μm) Thickness, equivalent to 4.13 miles, which is three times thicker than the standard 1 oz (35 μm) copper foil. This thickness is calculated based on copper weight per square foot, where 1 ounce is equal to 28.35 grams spread more than 1 square foot (0.0929 m²), with 3 ounces representing three times the density of mass.

What is the 3 oz copper PCB current?

3 ounces of copper PCB (105 μm) can usually handle 22â € “30A per 1mm width at an increase in temperature of 20 ° C, depending on whether the trail is in the inner or outer layer (inner layer: ~ 22a/mm; outer layer: ~ 30a/mm). This capacity comes from the standard IPC-2221, which considers the thickness of copper, traces, and an permitted temperature rise. For example, a 10mm width trail on the outer layer theoretically can carry 300A with the right thermal management.

Why Choose 3 OZ Copper PCB?

• Current capacity is higher “Supports up to 30A/mm in the outer layer, allows stable operations for high power applications without excessive heating.
• IMPROVING THEMAL MANAGEMENT “Thicker copper eliminates heat more efficiently, reduces thermal voltage and extending the life of the component.
• Increased endurance “Rejecting mechanical stress and thermal cycles better than thinner copper, ideal for demanding the environment.
• Space efficiency â € “allows a wider or fewer layer of traces in high -current design, simplifying the PCB layout and reducing costs.
• Reliable performance “Minimizing the decrease in voltage and signal loss, ensuring consistent power delivery in industrial and automotive applications.

When to use 3oz copper PCB?

• High current application: Power supply, motor controller, battery management system (BMS), and solar inverter requires thick copper (3oz) to minimize resistive losses and manufacturing heat under heavy loads.
• Critical System of Thermal Management: The automotive engine control unit (ECU), industrial power converter, and LED drivers use 3oz copper to increase heat dissipation, reduce dependence on external heatsinks.
• RF/Microwave power amplifier: A thick copper layer increases the current treatment in a high frequency power circuit, minimizing the loss of signals and thermal voltage in the communication system/wireless radar.
• Mechanical environment: Aerospace PCB, military, and automotive are subject to vibrations, shocks, or thermal cycles using 3oz copper for structural durability and reduced risks of trace fatigue.
• Corrosion resistant electronics: Marine, industrial, and outdoor devices benefit from thicker copper resistance to moisture, salt, and chemical exposure, ensuring long -term reliability.

3 oz copper pcb design guide

Below this 3 oz copper pcb design guide:
