Commercial, Industrial and Automotive are the industry's simple division of the chip industry, and their requirements for reliability are also completely different.

Commercial regulations

Commercial regulations and standards mainly restrict the devices in the consumer electronics industry. Because of the industry attribute, the terminal will be used for two or three years, and will be thrown away if it is broken. There is no consequence, and the iteration is fast. Therefore, the temperature range of - 20 ° C~65 ° C can be met, the service life is five years, and the corresponding reliability test is 500 hours. However, in recent years, many consumer electronics customers have continuously improved their standards and hope that the equipment will be more durable. Now, they basically require 1000 hours.

Work regulations

Industrial regulations and standards mainly restrict devices in industrial control, communication, medical and other industries. The equipment in these industries generally has a high unit price, a service life of more than 5 years, and a harsh environment. Therefore, the temperature range requires - 40 ° C~85 ° C, a service life of more than 5 years, corresponding to 1000 hours of reliability test, and some outdoor products require 2000 hours of reliability.

Vehicle gauge

The vehicle regulations and standards mainly restrict the devices in the automotive electronics industry. Because the terminal products are too expensive, they will work in various extreme environments, and they are related to the personal safety of passengers, so the vehicle regulations are formed into a separate system, following the AEC-Q series standards. For example, AEC-Q100 for single chip, AEC-Q101 for discrete devices, AEC-Q102 for photoelectric devices, AEC-Q104 for multi-chip devices, and AEC-Q200 for passive devices. According to different use scenarios, it can also be divided into Grade 0~3, for example, the temperature requirements vary from the lowest Grade 3 - 40 ° C~85 ° C to the highest Grade 0 - 40 ° C~150 ° C.

Automotive electronics generally require a service life of more than 10 years, and 1000 hours of HTOL under high temperature and pressure can also meet the service life of 10 years. The most special part of the car gauge is the special production line. The wafer production line and the seal test production line must meet the car gauge ITAF16949 standard, and the car gauge and non-car gauge must be processed separately. In recent years, auto competition has intensified, new car iteration has accelerated, and many non-core materials have also begun to use commercial standard products to play a marginal role. Because most commercial standard materials have been used for 1000 hours of reliability, the risk is small, so don't worry too much.

No matter what field of chip testing, the ThermoTST 780 Temperature Forcing Systems can easily cope with it. ThermoTST has a wider temperature range of - 80 ℃ to+225 ℃, providing a strong temperature conversion test capability. Temperature conversion from - 55 ℃ to+125 ℃ for about 10 seconds; It meets the requirements of various production environments and engineering environments through long-term multi-condition verification. TS-780 is pure mechanical refrigeration, without liquid nitrogen or any other consumable refrigerant. ThermoTST 780 is applied to reliability tests such as product characteristic analysis, high and low temperature temperature change test, temperature impact test, failure analysis, etc., meeting the domestic GJB system test standards and JEDEC test requirements.
