5oz Large Thick Copper PCB Board Full Turnkey Assembly For Medical Device

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​​

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​​.
