5G NETWORK ARCHITECTURE
① The dielectric constant (Dk) should be small enough and stable enough, and the smaller it is in general, the more stable it is.Good and high dielectric constants can cause signal transmission delays
② Dielectric loss (Df) should be small, which primarily affects signal quality. Therefore, the smaller the dielectric loss, the smaller the signal waste.
③ The thermal expansion rate should be as much as possible as copper foil, and the difference is temperature change. This is because copper foil is separated according to .
④ The water absorption rate should be low, and the high water absorption rate should be a dielectric constant in humid environments. and affect dielectric loss.
⑤ Heat resistance, chemical resistance, shock resistance, peel resistance should be good.
