High and low temperature test, also known as high and low temperature cycle test, is one of the environmental reliability tests. The purpose of the test is to evaluate the impact of high and low temperature conditions on the performance of equipment during storage and operation. Basically, all products are stored or operated at a certain temperature. View >>

What is electrical performance? Electrical performance describes some electrical parameters, such as rated voltage, current, active power, reactive power, resistance, capacitance, inductance and conductance. There is an internal correlation between structure and properties, in which the aggregated structure is an important factor that directly affects the properties of materials. In the process of partial discharge damage, the heat generated by partial discharge will increase the crystallinity and orientation of oil immersed insulating paper, which will also change its electrical properties.

Integrated circuit layout design refers to mapping the circuit design circuit diagram or circuit description language to the physical description level, so that the designed circuit can be mapped to the wafer for production. Layout is a graph containing relevant physical information such as device type, device size, relative position between devices and connection relationship between devices of integrated circuit. These graphs are composed of graphs located on different drawing layers. Integrated circuit design method involves a wide range and complex content, in which layout design is the basic technology of integrated circuit physical implementation. View >>

Applying for CNAs accreditation by the laboratory is a long cycle and complex thing. If the process is unclear, the preparation data is insufficient, or the personnel and equipment do not meet the requirements, it will greatly affect the acceptance and review progress, ranging from a few months to a new year, or even fail directly. Since the laboratory is recognized by CNAs, it is of such great significance. Therefore, it is particularly important to understand and clarify the necessary conditions for applying for CNAs recognition. The seven necessary conditions for the laboratory to apply for CNAs accreditation and how to rectify the nonconformities? The following is a detailed description of the core detection center.

Reliability test can generally be divided into engineering test and statistical test. The purpose of engineering test is to expose the defects, weak links and faults of products in design, process, components and raw materials, so as to provide information for improving product reliability. The purpose of statistical test is to verify whether the product meets the specified reliability or service life requirements. The following is a list of common military and civilian product reliability test standards, which I hope will be helpful to you. View >>
