With the popularity of self-driving cars, the value of semiconductors for individual vehicles is expected to increase, making it one of the key areas in the future. However, the shortage of automobile chips has made many well-known automobile brands announce to stop production, and many manufacturers flood into the automobile chip market. However, compared with other industries, the threshold of automobile chip market is higher, and the first threshold in front of them is the reliability of automobile chips.
Environmental reliability testing is a key step for automotive chips to enter the market. For automotive chips, different testing environment conditions will have different impact on the product and produce different failures, the environmental reliability requirements of different parts of the car are different, for different purposes, different installation parts of the automotive electronic products, its environmental reliability testing conditions are not the same. Passing these tests means that a car chip often has to undergo two to three years of rigorous evaluation before entering the industry.

Environmental reliability requires related devices to support it. According to relevant reports, environmental reliability testing includes mechanical environment test, climate environment test and comprehensive environment test. And the automotive chip environmental reliability testing, that is, to ensure that when the environment changes PCB function remains unchanged. The equipment involved includes thermal cycle test (TCT), thermal shock test, temperature and humidity deviation (THB) test, etc.

Opportunities for domestic equipment manufacturers

For the domestic market, the explosion of automotive chip market also brings opportunities for environmental reliability equipment manufacturers. Domestic environmental reliability testing manufacturers are a help to improve the reliability of automotive chips. Chengdu ChinaCryo Technologies CO.,LTD.   is one of the manufacturers of reliable environmental equipment in China. For the automotive field of environmental reliability testing, the company has launched high and low temperature impact airflow meter, constant temperature and humidity high and low temperature test chamber, contact high and low temperature impact machine and other equipment.

It is worth noting that Temperature Forcing Systems launched by Chengdu ChinaCryo Technologies CO.,LTD. The equipment adopts an intelligent automatic conversion expansion system, which can automatically adjust the refrigerant flow and intelligent electric heating function rate data value to match the rise and fall (load), and automatically simulate the output power data output value. According to the introduction, the use of this energy-saving design method, the company's equipment than energy-saving effect of more than 30%, each year to make long-term can save tens of thousands of yuan of electricity. Greatly improved the economic benefits of production enterprises and social benefits of energy conservation and emission reduction.

In addition, Chengdu ChinaCryo Technologies CO.,LTD. launched by Temperature Forcing Systems can produce (90 ℃ -- 200 ℃) compressed air jet from gas mouth, need only a few seconds to create another necessary environment, a temperature test is widely used in gas car chip ATE, FT test, compared with the previous issue, can greatly shorten the testing time.

As part of its foray into the semiconductor industry, Chengdu ChinaCryo Technologies CO.,LTD. has realized domestic substitution in certain areas of semiconductor environmental reliability equipment. For the automotive chip field, they also hope to be able to become the development of domestic automotive chip standards to help overcome the difficulties of automotive chip environmental reliability equipment.
