​35μm High-frequency microwave forward copper foil for High Frequency PCB

JIMA Copper is doing copper foil of Li-ion battery 4.5um to 14um more than 12 years. and production capacity 150000tons /years.

With a thickness of 35 μm, JIMAcopper is the ideal choice after careful development and repeated verification. In high-frequency PCB

applications, this precise thickness ensures that the copper foil has the best electrical properties. 

Features:

1,Special silane treatment with high peel strength 

2,Nanoscale treatment of copper nodules 

3,Excellent anti-oxidation and shelf life 

4,Excellent electrical performance (low dielectric constant, low dielectric loss, high insulation resistance)

5,outstanding surface quality, stable mechanical properties (high strength, good flexibility, good dimensional stability)

6,reliable thermal performance (high heat resistance, good heat dissipation)

7,special structural design (positive rotation structure, ultra-thin thickness)

Application:

1,(HDI) High Density Interconect

2,HSD (High Speed Digital)

3,Base Station / Server

4,Communication field (satellite communication, 5G communication, radar system)

5,aerospace field (avionics, satellite antenna)

6,medical field (medical equipment, medical imaging)

7,scientific research field (high-frequency electronics laboratory, microwave communication research)
