Quality Test Method Used in Microwave Frequency Converter

Abstract

The invention relates to the technical field of quality testing for a frequency converter, and provides a quality testing method used on a microwave frequency converter. The quality testing method comprises the following steps: product assembling testing, burn-in testing, high-temperature and low-temperature testing, shielding cover locking operation, thermal-testing and cold-soaking verifying and vibration falling-off testing. Product assembling testing is used. A product use state is tested in a vibration environment, noise environment, gain environment or / and signal isolation environment. The product of the invention is suitable for various environments. Burn-in testing is used and longer service life of the product is realized. High-temperature and low-temperature testing is used, and the product can be used at an extreme temperature. Shielding cover locking operation is used for preventing signal leakage, realizing a waterproof and leakage-proof performance, and preventing entry of foreign matter into the product. Thermal-testing and cold-soaking verifying is used, and an excellent waterproof effect of the product is realized. Vibration falling-off testing is used, and high stability of a product package is obtained. In a word, the microwave frequency converter which is manufactured according to the quality testing method used on the microwave frequency converter has advantages of excellent waterproof effect, high in-use stability of the product and long service life. Furthermore the quality testing method satisfies a requirement for high-standard and high-quality products.

Description

technical field [0001] The invention belongs to the field of frequency converter quality testing technology, in particular to a quality testing method used in microwave frequency converters. Background technique [0002] At present, in the existing microwave inverter quality testing technology, each manufacturer has its own production test standards, but generally include: testing the use of microwave inverters in environments such as vibration, noise, high temperature, and low temperature; The frequency converter is subjected to a waterproof test and a vibration drop test. [0003] However, due to the existing microwave inverter quality testing methods, the selection of conditions such as vibration, noise, high temperature, and low temperature is relatively rough. Therefore, the microwave inverter produced by the above method has relatively common electrical characteristics and is waterproof. The effect is poor, the product is unstable in use, and the life is short, which ...
