[Advantages of Yitong Detection]
a. Our professional technical team will tailor reliability design and testing solutions for your products.
Based on factors such as the design information, processing technology, materials used and usage environment of your product, and referring to the relevant experience of our laboratory and corresponding international standards, we will provide corresponding solutions for your product in response to the reliability design and testing requirements you have proposed.
b. A professional reliability testing team will conduct tests for your products;
The reliability testers of our company have over three years of testing experience, with solid theoretical and practical foundations. They have rich testing experience in products such as PCBS, leds, and power supplies.
c. Provide professional life assessment solutions and life tests;
Our laboratory has a solid theoretical foundation and experimental experience. In terms of the design of the test plan, based on relevant standards and all the information of the product, we can make the corresponding test plan. Regarding life assessment, since the life distribution of electronic products follows an exponential distribution and has a constant failure rate. Therefore, we can use MTBF (Mean Time Between Failures) as a reliability indicator for evaluating the lifespan of electronic products. Before conducting life tests, in accordance with the reliability design criteria, reliability estimation should first be carried out as the basic reliability indicators. Then, based on the estimated reliability indicators and demand indicators, they should be used as the data references for reliability tests. After the design of the product is completed, conduct reliability tests and evaluate the product's lifespan based on the test data.
d. We have also conducted certain research on accelerated life testing and can provide an accelerated life testing solution that is relatively recognized in the industry.
Accelerated life testing, as an extension of life testing, has advantages such as low cost and short time. It is now widely demanded in the industry. However, due to the lack of industry standards, it is not adopted as the acceptance standard by most enterprises. However, most enterprises will take this test as the life assessment test of their products. Based on the data obtained from this test, they will evaluate the lifespan of the products and thereby determine whether the design plan of the products needs to be modified. Design flaws can also be identified from this experiment and corresponding modifications can be made. The Arrhenius model is the most commonly used model in the industry for accelerated life tests. The test conditions are determined based on the actual usage conditions and limit conditions of the product, and the actual product life is calculated according to the acceleration factor.
e. For all technical and testing questions regarding reliability that you need, you will receive the most professional answers.
Our laboratory has five years of testing experience and a strong reliability design and testing team. We have conducted certain research in reliability prediction, reliability modeling, reliability testing, reliability assessment, FMECA and systems engineering, etc. We can solve related problems for customers and create reliability design and testing plans.
f. Efficient on-site test arrangement and expedited issuance of product inspection reports can solve your urgent problems.
