Thin Film Material

Oxygen-Free High Thermal Conductivity Copper – Class 1 OFHC Slab

OFHC(Oxygen-Free High Thermal Conductivity Copper), that requires high purity, low oxygen content, and high electrical conductivity, is mainly used to manufacture FCCL (Flexible Copper Clad Laminate) film, which is a raw material for FPCB (Flexible Printed Circuit Board), and Flexible Input/Output Material (FLOG), an ultra-thin/metal precision layered composite material. YOOCHANG METAL IND. is the first in Korea to use Class 1 OFHC Slab to produce world-class high-quality sputtering targets and other products.

The sputtering target for manufacturing FCCL, the original material of FPCB, requires features such as high purity, high electrical conductivity, low impurity content, low oxygen concentration, and low hydrogen embrittlement. Particularly, high oxygen concentration causes pores in the sputtering film, causing serious defects. Our high-quality oxygen-free copper sputtering target has fewer substances that cause a decrease in electrical conductivity and has high electrical conductivity. And its oxygen concentration is less than 2.1ppm on average, pores are not generated, and hydrogen embrittlement hardly occurs, so it does not impair FCCL features.
