Treated Rolled Copper is a tough pitch copper foil from JX Nippon Mining & Metals.
The characteristics of HA/HA-V2 foil are significantly enhanced when compared to usually rolled copper foil via adjustments to the grain size and crystallographic orientation.
- Remarkable enhancement in vibration resistance
- Minimal cracking due to exceptional flexibility
- Increased pliability due to vibration resistance
Surface Treatment
Several types of surface treatments are available to address customer requirements.
- Treatments are greatly analyzed corresponding with the needs for high frequency and fine patterning
- A range of rust-proofing treatments obtain excellent resistance to chemicals, heat and soldering
- Fine and low roughness treatment achieves improved adhesion property to resin
