0.018mm * 520mm Single Side Shiny RA Cu Foil For FCCL With Japanese Technology

Description :

Civen RA Copper Foil is rolled from pure copper ingots, the process including purifying copper ores, make into copper cathodes, ingoting, rolling, annealing, washing, testing, slitting and packing.
Our copper ores are imported from South America, which were famous for their copper mining.
This is high quality copper and has a wide range of applications based on conductivity, corrosion resistance, workability, and beauty.
110-anneal (Electrolytic Tough Pitch or ETP) dead soft. Min 99.96% CU

Applications:

Advantange :

Copper surface are can be increased and can improe the fry or wet green oil film 's adhesion with copper foil.
it can supports the Anti-peeling of the solder oil when making HDI board by the mathod of chemical shen tin, chemical nickel gold and etc.
