Assuming that a computer has an MTBF of 30,000 hours, is it possible to run this computer continuously for 30,000 hours to detect it? Of course not, otherwise there are so many products to be used for decades are not finished testing. MTBF value of the calculation method, the more common sexual standards are MIL-HDBK-217 (the U.S. Department of Reliability Analysis Center and Rome Laboratory proposed and become the industry standard, specifically for products), GJB/Z299B and Bellcore (Unitech Testing Laboratory and become the industry standard for civilian products). MTBF industry standard).
What is the use of MTBF test
1. Evaluate whether the product can meet the reliability targets
2. In the program certification stage, through the reliability of the projected, compared with the reliability level of different programs, to provide a basis for the optimization of the best program
3. In the design stage, through the reliability of the projected, to find out the main weaknesses of the impact of system reliability, to take design measures to improve the reliability of the system
4. To provide a basis for reliability growth test, verification and cost accounting
What products need to do MTBF test
1. Computer: computers, displays, mainframes, computer components, medical equipment and other precision instruments, etc.;
2. Electronics and communications: cell phones, radio frequency devices, electronics, communications components, etc.;
3. Communication components, etc.
3. Electrical appliances: home appliances, lamps, transformers and other types of home appliances and electrical equipment;
4. Electronic components, electronic connectors, PCB & PCBA, etc.
In short, the MTBF value of the electronic products up to the standard, the product's reliability of the quantitative indicators up to the standard.
