All Different Types of Power PCB Speed up Your Projects

Power PCB (2oz)

This is a 4layer power PCB, whose copper thickness of the inner and outer layer is 2oz, the trace width/space is 10mil/10mil, what’s more, this is a normal board and most PCB manufacturers can produce it, whose application is power supplies, power converters.

Power PCB (3oz)

Heavy copper is more commonly used for PCBs featuring 3oz of copper in the internal and external layers. This term is also applied to any circuit with a copper thickness of more than 4 Oz/ft2. The term extreme heavy copper PCB refers to PCBs with 20 Oz/ ft2 to, which has 200 oz. per ft2

Power PCB (4oz)

This is a 6layer heavy copper PCB with 4oz, the applications are electric vehicles, simulating solar arrays for the development of inverters, steering magnets for particle accelerators, powering radar systems, driving traction controllers for locomotive development.

Power PCB (5oz)

Heavy copper printed circuit boards feature 5 ounces of copper in outer/inner layers. These printed circuit boards are valued immensely, due to their thermal management capabilities. The heavy copper composition helps keep inner components cool, and improves their performance.

Power PCB (6oz)

PCBMay is a highly experienced PCB manufacturer that can develop and produce a superior heavy copper PCB product of the highest quality. We can offer a 6oz thick copper PCB manufacturing service,whose trace width/space is 16/22mil,surface finished is Leaded free HAL.

Power PCB (7oz)

Heavy copper PCB has the capability to conduct and implement an additional layer to keep things safe and work perfectly.It is the newest trend in the PCB industry that ensures hefty electrical current flow through the electrical circuits.This kind of heavy copper 7oz is mostly prototyping PCB.

1, What Thickest Copper Can You Make?

We can produce heavy copper reach 12oz.

2, What Is The Standard Delivery Time For Power PCB Boards?

It depends on the exact copper of each board, mostly it will be inscreasing 1-2days after the copper adds 1oz from beginning of 3oz.

3, Can You Produce The Different Copper Thickness For Each Layer?

Yes, we can, typically the copper from inner layer and outer layer is different, such as 2oz for inner layer, 6oz for outer layer.

4, What Is The Trace Width And Space For Heavy Coper PCB?

It depends, normally, 2OZ: 6/8mil, 3OZ: 6/12mil, 4OZ: 7.5/15mil,5OZ: 9/18mil, 6OZ: 10/21mil, 7OZ: 11/25mil, 8OZ: 12/29mil, 9OZ: 13/33mil , 10OZ: 14/38mil

5, What Is The Standard Board Thickness And Can You Produce 2.4mm Or 3.2mm Thick Boards?

The standard board thickness is 1.6mm , this provides a good balance between strength and weight. A thickness of 2.4mm or 3.2mm is also available.

6, What Copper Thickness Do You Use And Are There Other Thicknesses Available?

The copper thickness of most PCB boards is 35um(1oz),our capability can reach 12oz.
