The respirable dust quality can be obtained by measuring the oscillating frequency of the oscillating tube, which can realize respiratory dust monitoring combined with flow measurement. But the manufacturing process of the hollow cone tapered element stainless steel oscillating tube is complicated, and the finished product rate is low; the product quality dispersion is larger than the others. With...
Life prediction is one of the newly arisen key technology for promoting the reliability and quality of electronic products. But, the effect of the prevalent life prediction methods is not satisfactory; most of them are on the stage of theoretical research and lack of engineering practicability. In this paper, a methodology of life prediction based on accelerated degradation testing is introduced....
The complex electronic components should be tested during either the period of design and manufacture or the period of debugging and running to ensure that their application quality meet the requirements. However, the traditional testing technology encounters tremendous difficulties and the cost of testing is expensive with the rapidly development of the electronic components' integrated technology...
