Mobile phone backplane

5G communication technology cannot use metal backplanes (including those with antennas) because the metal will shield the signal and cannot reach the standard
The nominal rate is therefore replaced by ceramics.

Because of its excellent physical and chemical properties, zirconia is widely used in various industrial and technical fields. The use of zirconia ceramics as a backplane mobile phone is mainly loved by the public because of its excellent material properties. Due to its high hardness, it can pass the drop test; the texture and color effect are better, and it can be made into an integrated shell.

Characteristics of ceramic materials:
Ceramic materials have the characteristics of good hand feel, high hardness, wear resistance, elegant appearance, no signal shielding (relative to the metal backplane) and so on. The ceramic material can give the mobile phone backplane better wear resistance, and less scratches like glass, plastic, aluminum alloy, stainless steel, etc.
