By increasing the density of the roughening treatment particles compared to previous products, this ultra low roughness copper foil boasts stronger adhesion to various substrates without increasing roughness. In addition to adhesion strength, it also offers various other features that enhance functionality and directly improve board reliability, such as long-term heat resistance and chemical resistance.
● Low profile for FCCL
● Grain structure of copper foil leads to high flexibility
● Excellent etching performance
● The treated foil is red or black
● Low profile enables to make fine circuit pattern
● Casting and lamination type FCCL
● Fine pattern FPC&PWB
● Chip on flex for LED
● For FPC or Inner layer
● Despite the low roughness, this foil offers high adhesion strength, heat resistance, and high chemical resistance for use in a wide variety of application
