Heavy Copper
Generally, the PCB copper foil with a nominal
thickness of 105 μm or over is collectively referred to as a thick copper foil
(including the surface-treated electrolytic copper foil and rolled copper
foil). The PCB and copper foil manufacturing industry domestically and abroad
are more accustomed to specifically divide the thick copper foil into three
varieties based on its nominal thickness, the one with thickness of 105μm (≥
3oz) ~ 240μm or over is called thick copper foil; the one with thickness of 300μm or over is called super-thick copper foil; the one with thickness of
600μm and above is referred to as super MAX copper foil.
The thick copper foil and super-thick copper
foilbelong to a kind of special PCB copper foil.
In addition to its conventional electrolytic copper foil (or rolled copper
foil) performance, it also has such special performance as the conducting layer
of high current board or the inner core cooling metal layer of the high-current
PCB, and other special performance requirements. These special performance
requirements are to meet the application conditions, processing conditions and
other aspects from its downstream products. The application performance
requirements of it is mostly expressed in the characteristics that the
conducting circuit of thick copper can stably carry high current, and can
better distribute high heat generated by the loaded high current in a
substrate.
In recent years, with the
expansion of application field of heavy copper printed circuit board, and the
increase of production and sales, the production and sales of thick copper foil has also been significantly improved. According to statistics, its production
and sales have accounted for 5 ~ 6% of the world's production and sales of
electronic copper foil, which is 17,000 ~ 20,000 tons / year.
