Automakers must design vehicles to thrive in a broad spectrum of environments, from snowy tundra to scorching deserts. The purpose of automobile reliability test is to assess the automobile and its components. With the test chamber, it’s easy to cause the automobile failure in design, manufacturing and other aspects, directly exposing the problems and weak links. In view of this, the failure reason should be found in time, and the production should be continuously improved. Eventually, innovate design ideas, and accumulate experience for new product development.
Based on new technologies and new materials, we will modernize the development and utilization of traditional renewable energy. We will replace fossil energy with renewable energy that has limited resources and pollutes the environment. Among them, solar energy, wind energy, biomass energy, tidal energy, geothermal energy, hydrogen energy and nuclear energy are the key development energy determined by the United Nations. The collectors and converters of new energy often need to be placed in the outdoor environment, so the detection of these equipment materials and design is an important part.
Semiconductor products are often used in high-end electronic equipment, such as medical devices and communication equipment, so its quality and reliability can not be ignored, reliability testing is through a series of experiments and analytical means to evaluate the reliability，stability and life of semiconductor devices under specific conditions, is an important means to ensure product quality and stability, and also the basis of customer trust and satisfaction. Therefore, the establishment of scientific and rigorous semiconductor reliability test standards is crucial to the development of the semiconductor industry.
It is extremely important for the high-tech electronic communication industry to improve the quality of the company's products, meet the requirements of current international standards and specifications (IEC, UL, MIL, IPC, GB, etc.), improve the company's competitiveness and quality, reduce the product maintenance rate, customer complaints and other related problems and intangible costs and time waste. In the process of storage, transportation and use of electronic and communication high-tech products, ion migration, condensation, changes in electrical characteristics and other phenomena will cause consumers to lose confidence. The products must comply with international standards and reduce product damage in order to gain the trust of every customer.

Bellcore GR78-CORE is one of the specifications used in early surface insulation resistance measurement (such as IPC-650). The relevant precautions in this test are organized for reference of personnel who need to carry out this test, and we can also have a preliminary understanding of this specification. Test purpose: Surface Insulation Resistance Testing 1. Constant temperature and humidity test chamber: the minimum test conditions are 35°C±2°C/85%R.H., 85 ±2°C/85% R.H. 2. Ion migration measurement system: Allowing insulation resistance of the test circuit to be measured under these conditions, a power supply will be able to provide 10 Vdc / 100μA. Test procedure: a. The test object is tested after 24 hours at 23°C (73.4° F)/50%R.H. environment b. Place limited Test patterns on an appropriate rack and keep the test circuits at least 0.5 inches apart, without obstructing air flow, and the rack in the furnace until the end of the experiment. c. Place the shelf in the center of the constant temperature and humidity test chamber, align and parallel the test board with the air flow in the chamber, and lead the line to outside of the chamber, so that the wiring is far away from the test circuit. d. Close the furnace door and set the condition to 35 ±2°C, at least 85%R.H. and allow the furnace to spend several hours stabilizing e. After 4 days, the insulation resistance will be measured and the measured value will be recorded periodically between 1 and 2,2 and 3,3 and 4, 4 and 5 using an applied voltage of 45 ~ 100 Vdc. Under the test conditions, the test is sent out the measured voltage to the circuit after 1 minute. 2 and 4 are periodically at an identical potential. And 5 periodically at opposite potentials. f. This condition only applies to transparent or translucent materials, such as solder masks and conformal coatings. g. As for multilayer printed circuit boards required for insulation resistance testing, the only normal procedure will be used for insulation resistance testing circuit products. Extra cleaning procedures are not allowed. Method of conformity determination: 1. After the electron migration test is completed, the test sample is removed from the test furnace, illuminated from the back and tested at 10 x magnification, and will not be found to reduce the electron migration (filamental growth) phenomenon by more than 20% between the conductors. 2. adhesives will not be used as a basis for republication when determining compliance with the 2.6.11 test method of IPC-TM-650[8] to examine appearance and surface item by item. Insulation resistance does not meet the requirements of the reasons: 1. Contaminants weld the cells like wires on insulating surface of substrate, or are dropped by water of test furnace (chamber) 2. Incompletely etched circuits will reduce insulation distance between conductors by more than permitted design requirements 3. Chafes, breaks, or significantly damages the insulation between conductors
