How to Quote & Order Heavy Copper PCB

Heavy copper PCB is commonly used in high current, power supply, industrial control, automotive, and other demanding electronic applications. This page explains how to request a quote, what information to prepare, and what design points are important before ordering heavy copper PCB.

What Is Heavy Copper PCB?

A heavy copper PCB is a printed circuit board manufactured with thicker copper than standard PCB designs. Standard boards often use 1 oz copper, while heavy copper PCB projects commonly use 2 oz, 3 oz, or 4 oz copper depending on current and thermal requirements.

Heavy copper PCB is often selected for applications that need stronger current carrying capability, improved thermal handling, and better mechanical durability in demanding environments.

Typical examples: power supply modules, industrial control boards, motor control, power distribution circuits, and other higher current electronic applications.

Our Heavy Copper PCB Capability

Our clearly stated standard heavy copper PCB capability currently supports copper weight up to 4 oz.

Item Current Statement
Supported copper weight 1 oz, 2 oz, 3 oz, 4 oz copper
Standard heavy copper range Up to 4 oz copper
Above 4 oz copper Please contact us for confirmation before quote or order
Note: Final manufacturability still depends on trace width, spacing, board thickness, hole size, layer count, and overall board design.

What Information to Prepare Before Requesting a Quote

To receive a more accurate heavy copper PCB quote, please prepare the following information:

  1. Board size (single board size or panel size)
  2. Layer count
  3. Required quantity
  4. Copper weight, such as 2 oz, 3 oz, or 4 oz
  5. Board thickness
  6. Surface finish requirement
  7. Solder mask color and silkscreen color
  8. Gerber files and drill files if available
  9. Any special fabrication notes

If your project has unusual stack-up requirements, tight spacing, small drills, or special reliability requirements, that information should also be included.

Important Design Notes for Heavy Copper PCB

  • Heavier copper usually requires wider trace width.
  • Larger spacing may be needed in some designs.
  • Thicker copper can affect etching performance.
  • Hole size and plating requirements may need closer review.
  • Heavy copper PCB usually costs more than standard 1 oz PCB.
  • Lead time may be longer depending on copper thickness and board complexity.

Heavy copper is not simply a material upgrade. It also affects manufacturability, routing flexibility, cost, and process control. For more complex heavy copper boards, Gerber review is strongly recommended before final order confirmation.

Lead Time for Heavy Copper PCB

Heavy copper PCB orders may require additional review time. Actual lead time depends on:

  • Layer count
  • Copper weight
  • Board thickness
  • Hole size and routing complexity
  • Overall production schedule at the time of order

If your project is urgent, please contact us before placing the order so we can confirm scheduling and process suitability.

Not Sure What 1 oz, 2 oz, 3 oz, or 4 oz Means?

Heavy Copper PCB FAQ

Can I order 2 oz, 3 oz, or 4 oz copper PCB online?

Yes. You can start from our online quote page. Please clearly state your required copper weight and include Gerber files when available.

Do heavy copper PCBs cost more than standard PCBs?

Yes. In most cases, thicker copper increases both material cost and fabrication complexity, so pricing is usually higher than standard 1 oz PCB.

Can I order PCB above 4 oz copper?

For copper thickness above 4 oz, please contact us for confirmation first. Manufacturability needs to be reviewed case by case.
