5OZ Thick Copper Large PCB Board for Medical Device

♦ What is Heavy Copper PCB?

A Heavy Copper PCB is a specialized printed circuit board that uses exceptionally thick copper layers (typically ≥ 3 oz/ft², up to 20 oz/ft² or more) for high-current, high-power, or high-thermal applications. Unlike standard PCBs (which use 1-2 oz copper), heavy copper PCBs can handle extreme electrical loads, heat dissipation, and mechanical stress.

♦ Features of Heavy Copper PCB

✅ High Current Capacity – Supports 10A–100A+ per trace (vs. ~1–5A in standard PCBs).
✅ Enhanced Heat Dissipation – Reduces hotspots by spreading heat through thick copper planes.
✅ Strong Mechanical Structure – Resists thermal expansion, vibration, and warping.
✅ Space Efficiency – Fewer layers needed compared to parallel traces in standard PCBs.
✅ High Reliability – Ideal for harsh environments (industrial, automotive, aerospace).

♦ Heavy Copper PCB vs. Standard PCB

Parameter	Heavy Copper PCB	Standard PCB
Copper Thickness	3 oz – 20+ oz/ft²	0.5–2 oz/ft²
Current Handling	10A–100A+	<5A
Thermal Performance	Excellent	Moderate
Cost	Higher (complex manufacturing)	Lower
Typical Applications	Power electronics, motor drives	Consumer electronics, low-power devices

Heavy Copper PCBs are essential for high-power, high-reliability applications where standard PCBs would fail. They excel in thermal management, current handling, and durability, making them ideal for industries like automotive, aerospace, and industrial automation.
