Copper Clad

What is Copper Clad FR-4?

Copper clad is FR-4 glass epoxy sheet laminated with copper. Sheets ranging in thickness from .007" to .250" are laminated either one side or two sides with copper. The thickness of the copper is measured in ounces per square foot with a typical range of 1/2 ounce to up to 2 ounces. Of course, the sheet thickness and the copper clad weight can be specified outside these typical ranges.

Copper Clad FR-4 has become the standard of the printed circuit industry. This product possesses high mechanical strength, good machinability and consistent drilling quantities, such as minimum bit wander and excellent hole plate-through.

The resin for FR-4 is brominated to provide a ul 94 V-0 fire resistance without degrading the laminate quality or performance. No other retardants or additives are introduced to the material.

With circuitry traces getting narrower, spaces tighter, and plated through holes occupying a greater percentage of circuit board requirements, the dielectric strength and qualities of FR-4 are critical to both high yield and product reliability.
