Abstract

The invention relates to a processing method for a high-toughness cover plate of a 5G mobile phone. The processing method comprises the following steps of pretreatment of zirconia granulation powder,dry-pressing formation, cooling, vacuumizing packaging, isostatic press formation, step sintering, after-combustion and thickness grinding, cutting, accurate grinding and polishing. The produced coverplate has the advantages of high rigidity, high toughness and the like, and the performance can meet the demand of a consumer of the 5G mobile phone.

Description

technical field [0001] The invention relates to a processing method for a high-toughness cover plate used for 5G mobile phones. Background technique [0002] 5G is the fifth-generation communication technology. It has the characteristics of high speed (100 times faster than 4G), low latency (only 1ms), low energy consumption, and full network coverage. All countries attach great importance to 5G technology. On June 14, 2018, the international communication standardization organization 3GPP officially approved the full-function standardization of the first phase of the fifth-generation communication 5G. In 2018, my country established the largest domestic 5G field technology test network in the Yangtze River Delta region. It was the first to start commercial use in 2019, and it will become one of the first commercial areas in China in 2020. In order to cooperate with the promotion and application of 5G communication technology, China's Huawei is preparing to develop 5G chips...
