1/2oz HD electrolytic copper foil for Polyimide board and Epoxy board

 

There are various types of copper foil are offered; in a range of weights (thicknesses). Their characteristics differ, and an understanding of these differences is important to ensure the correct selection of copper foil for each application or environmental condition.

 

Crystalline Structure
Electrodeposited copper crystals tend to grow lengthwise in the Z-axis of the foil. Typically, a polished section of
electrodeposited copper foil has the appearance of a picket fence, with long crystal boundaries perpendicular to
the foil plane. Rolled copper crystals are broken and crushed during the cold rolling operation. They are smaller
than the electrodeposited crystals, and have irregular, spherical shapes, nearly parallel to the foil plane.

 

Copper Foil Roughness Measurements
An optical profiler can be used to analyze the three-dimensional surface profile of a copper foil to subsequently
determnie its RMS roughness. RMS or Rq is the “root-mean-squared” roughness calculated over the profiled
area. The surface morphology of half ounce electrodeposited copper on figure 1 clearly shows that the treated
side has granular dendritic structure and the untreated side has a smoother surface.
