Pay attention to product performance, quality, delivery time, safety, and service to meet customer needs and win customer praise.
The managers at all levels of the company ensure that all tasks are effectively implemented and maintained in accordance with the company's quality system to comply with the IATF 16949 international quality standard.
Quality goalsEnsure that the quality of the product can satisfy customers
Make products comply with international standards
Continuous improvement to achieve zero defects
MTBF (Mean Time Between Failure)
Mean time to failure: Refers to the average time between failures after a period of use of the product.
For example: Notebook computers (Notebook) belong to this category.
MTTF (Mean Time To Failure)
Average life span: refers to the average life span of a product or part after use until it fails to be used anymore.
For example, the product characteristics of fans fall into this category.
CL (Confidence Level)
Reliability level (range): Take "30,000 hours of MTBF, 90% confidence level" as an example. The observed value of each test is MTBFi, which means that 90% of the times the value of MTBFi falls over 30,000 hours.
L10 (Life 10)
Take 1 batch of fans for Life test, when the cumulative failure rate reaches 10% of the time; the L10 value of its temperature is about 1/9.5 times the MTTF of the temperature.
MTTF and MTBF are both standards for reliability estimation. The difference is that MTBF is used in repairable or expensive industries (such as airplanes and automobiles), and MTTF is used in non-repairable or cheaper industries (such as fans). , Lamp). After a life acceleration experiment, the observed MTTF/MTBF is obtained, such as 70 degrees and 30,000 hours (CL90%). This MTTF/MTBF value is only the estimated life of a product, but not all product life can be 100% guaranteed. .
