What is Heavy copper PCB?

Heavy copper PCB products are widely used in power electronic equipment and power supply system.The additional copper PCB thickness enables the board to conduct a higher current, achieve good thermal distribution and implement complex switches in a limited space.

This unique type of thick copper PCB has a finished copper weight of more than 4 ounces (140 microns), compared to the standard PCB copper thickness of 1oz or 2oz.

What is HDI PCB?

HDI stands for High Density Interconnector. A circuit board which has a higher wiring density per unit area as opposed to conventional board is called as HDI PCB. HDI PCBs have finer spaces and lines, minor vias and capture pads and higher connection pad density.

What is copper weight on PCB?

1 ounce

Copper Weight or Copper Thickness in a Printed Circuit Board represents the thickness of 1 ounce of copper rolled out over an area of 1 square foot. For example, a PCB that has a copper weight of 1 oz will have a layer of copper that is 1.4 mils in thickness.

What is the thickness of 1 oz of copper on a PCB?

1.4mils

The copper in a PCB is rated in ounces, and represents the thickness of 1 ounce of copper rolled out to an area of 1 square foot. For example a PCB that uses 1 oz. copper has a thickness of 1.4mils.
