Heavy Copper PCB Manufacturing

Copper Thickness up to 40 OZ (1400 µm) | FR4 / Aluminum / Copper / Ceramic Base

Heavy Copper PCB Types & Capability Range

Thick copper traces and planes for high current, high power and thermal-critical designs. Built on FR4, Aluminum, Copper or Ceramic base with copper up to 40 OZ.

Up to 40 OZ Copper

Extreme copper thickness for very high current-carrying and thermal loads.

Selective Thick Copper

Selective thicker copper in the same layer, combining multiple copper weights on one board.

Multilayer Heavy Copper

Multilayer heavy copper circuit boards with heavy copper-plated through-holes and vias.

Heavy Copper + Copper Coin

Hybrid heavy copper with embedded copper coin acting as a built-in heat sink.

Heavy Copper PCB Base Materials

Heavy copper builds are not tied to one laminate brand — the base material is selected per design.The base consists of FR4 / Aluminum / Copper / Ceramic.

FR4

Standard reinforced epoxy base for most heavy copper boards.

Aluminum

Metal-core option for enhanced heat spreading.

Copper

Copper base / copper coin for maximum thermal conduction.

Ceramic

Ceramic base for high-power and high-frequency hybrid builds.

Frequently Asked Questions

1. What is a heavy copper PCB?

A heavy copper PCB uses thicker copper traces and planes than standard boards — typically 3 to 20 oz/ft², and at Andwin up to 40 OZ (1400 µm). This raises current-carrying capacity and improves heat dissipation for high-power designs.

2. What copper thickness can you manufacture?

Standard heavy copper ranges from about 3 oz/ft² to 20 oz/ft²; we have experience building heavy copper PCBs up to 40 ounces (1400 µm). Exact thickness depends on your stack-up and base material — confirm with sales.

3. Which base materials are supported?

Per the source page, the base material consists of FR4 / Aluminum / Copper / Ceramic. We select the base per design and application.

4. Can you do selective thick copper and multilayer builds?

Yes. We can make selective thicker copper in the same layer (combining multiple copper weights on one board) and build multilayer heavy copper boards with heavy copper-plated through-holes and vias.

5. What is the lead time and minimum order quantity (MOQ)?

Lead time and MOQ depend on copper thickness, layer count and order volume. Send your Gerber and stack-up to our sales team for an exact quote and schedule — we support prototype lots and scale to volume.
