JMC won the national invention patent! A chip agility verification technology.

Recently, good news came from the State Intellectual Property Office, the chip related patents "A test method for anti-static ability of package chip" and "Hall effect efficiency test device for wheel speed sensor" purchased and applied by JMC have been granted national invention and utility model patent authorization respectively, which is of great significance under the current situation that chip supply in many industries is still tight.

The outbreak of COVID-19 in early 2020 strained global chip supplies, with the development of electrification and intelligentization, the automotive industry has become a major disaster area for chip supply.
According to statistics, in 2021, the shortage of automotive chips led to the global production of 10.2 million cars; Oems and suppliers are looking for new sources of chips because of the shortage. The chips of these new channels have great quality risks due to the uncertainty of storage and transportation conditions. Among them: a variety of reasons caused by packaging chip electrostatic damage. In addition, with the rapid development of Chinese machinery system electronics industry and the progress of mechanical-electronic technology, the competition in the field of mechanical -electronic processing is becoming more and more fierce, and the requirements of technical indicators of wheel speed sensors for vehicle are getting higher and higher.

The procurement expert team to overcome difficulties, deep research, first put forward the concept of "anti-cumulative static power of the package chip", "the maximum effective gap between the wheel speed sensor and the hub gear ring", through "anti- cumulative static power of the package chip" for the industry to judge the quality of the package chip provides a new fast and accurate way. The problem of Hall effect efficiency monitoring of wheel speed sensor chip for vehicle is solved and the industry gap is filled. At the same time, the two patents have a clear technical route, rigorous thinking logic, simple structure, accurate and feasible measurement, low manufacturing cost, and are very easy to be popularized and used.
