From PCB design to mass production, Fanway delivers quick-turn PCB manufacturing services as one-stop solutions to address your diverse project requirements and accelerate your time-to-market.
Compare with FR-4, CEM-1 PCB save 30–50%.
It is easy to be formed by stamping, supports rapid production and has a short delivery time.
The dielectric constant (about 4.5@1MHz) is close to FR-4, meeting the requirements of most low-frequency circuits.
In fields such as LED lighting, it can effectively control costs while optimizing heat dissipation performance.
