<p>
Copper in circuit boards carries electrical current and signals. The thickness
of copper layers in PCBs typically ranges from H oz to 1 oz. Copper thickness is
measured in weight, where 1 oz equals .0014 inches or 35 micrometers in nominal
thickness. For applications requiring high current and amperage, such as power
supplies, thicker copper is necessary. PCBs with finished copper >2 oz are
classified as heavy copper.
