According to the oxygen content and impurity content, oxygen free copper is divided into No. 1 and No. 2 oxygen free copper strip. The purity of No. 1 oxygen-free copper reaches 99.97%, the oxygen content is not more than 0.003%, and the total impurity content is not more than 0.03%; The purity of No. 2 oxygen-free copper reaches 99.95%, the oxygen content is not more than 0.005%, and the total impurity content is not more than 0.05%.
PCB Copper foil is a thin, continuous metal foil deposited on the base layer of a circuit board, It is easy to adhere to the insulation layer, to accept the protective layer of printing, corrosion after the formation of circuit patterns. As an important material to made of CCL and printed circuit board (PCB). PCB copper foil (purity of more than 99.7%, thickness 5um-105um) is one of the basic materials of the electronics industry.
Soft copper strip, High purity, fine organization and extremely low oxygen content.A freshly exposed surface has a reddish-orange color. It is used as a conductor of heat and electricity, a building material, and a constituent of various metalalloys. It has excellent electrical conductivity, thermal conductivity, corrosion resistance , weather resistance and processing properties, can be welded and soldered.
Pure copper strip is soft and malleable; a freshly exposed surface has a reddish-orange color. It is used as a conductor of heat and electricity, as It has excellent electrical conductivity, thermal conductivity, corrosion resistance , weather resistance and processing properties, can be welded and soldered.
