To carry out reliability design, it is necessary to collect, examine the reliability of the information, so that there is a sufficient basis for the design. Reliability of information mainly from the electronic components of product development, manufacturing, testing, use, and SN74LS612FN datasheet and failure analysis, in general, the main contents of the reliability of information: reliability level of similar products, there main failure mechanism or failure mode. manufacturing test data, monitoring data and SN74LS612FN price and times information, test data, quality analysis of information, failure phenomenon and SN74LS612FN suppliers and failure analysis information. customers, users or the market for product performance, features, reliability requirements and expectations. customers, failure to use information about site users, failure analysis r...
