Heavy Copper PCB, Heavy Copper PCB Manufacturer
Heavy Copper PCB, Heavy Copper PCB ManufacturerHeavy Copper PCBs are printed circuit boards with 3 or more ounces of finished copper in the inner and/or outer layers.Heavy Copper PCB General InfoHeavy Copper Board does not have a
set of definition per IPC. According to PCB industry, however, peopel
generally use this name to identify a printed circuit board with copper
conductors 3 oz/ft2 - 10 oz/ft2 in inner and/or outer layers. And
Extreme heavy copper PCB refers to 20 oz/ft2 to 200 oz/ft2 printed
circuit board.Heavy copper normally used for a
various products but not limited to: high power distribution, heat
dissipation, planar transformers, power convertors, and so on.Design Guide for Heavy Copper PCB The minimum width and
thickness of a heavy copper PCB conductor is determined primarily on the
basis of the current carrying capacity required and the maximum
permissible conductor temperature rise. A circuit board trace, depending on
its size and manufacturing process, may not be rectangular in shape.
Heavy copper conductors can significantly add to the overall board
thickness.Additive (plating) processed are preferred to subtractive (etching) processes but are more expensive). Typical conductor width/spacing/thickness tolerance is +/-20%, although tighter tolerance is achievableCapability of Heavy Copper PCB
