Plans Made to Raise Production Capacity of Rolled Copper Foil for Flexible Printed Circuits (FPC)

JX Nippon Mining & Metals (President: Shigeru Oi; hereinafter “the Company”) has decided to put back into operation the surface treatment equipment that had been idle in the Copper Foil Department of the Hitachi Works, boosting production capacity of rolled copper foil.

The Company’s rolled copper foil for flexible printed circuits (FPC), used extensively in making smartphones thinner and advancing their performance, currently boasts an 80 percent share of the world market. As FPC are starting to find other applications including in-vehicle electronic components, demand is expected to grow further, prompting the decision to boost production capacity of rolled copper foil for FPC use.

Rolled copper foil for FPC use is produced entirely in the JX Nippon Mining & Metals Group, in a unique integrated production process extending from the copper ingots used as raw materials to rolling and surface treatment. Last year, the company began taking steps to boost capacity of manufacturing equipment, introducing a new finishing mill and degreaser at the Kurami Works. Along with this move, the surface treatment equipment that had been idle in the Copper Foil Department of the Hitachi Works will be put back into operation in April of this year, as measures are being taken to improve quality and raise productivity.

The Company plans to continue boosting production capability as needed to meet the expected demand growth for rolled copper foil for FPC use, ensuring a stable supply to these markets.
