We often see connectors with stable, reliable, long life and other performance characteristics, such connectors are high quality, high quality. Said that the technical difficulty is low stability is the king, then what is the stability of the connector? How is it stable and reliable?
The stability of the connector is that the connector has strong anti-environmental interference during use, does not lose its effectiveness due to the harsh environment, and has excellent signal transmission current capability, long duration and excellent durability. Therefore, the service life can be made longer in the course of use, and the function can be stably realized without failure for a long time.
So how do manufacturers guarantee the stability, reliability and long life of the connector?
Quality identification usually involves a series of continuous tests (ie, testing of plating type and coating thickness, terminal materials, etc.) in conjunction with the design requirements, which will allow Connector/Socket to conditionally meet a specific specification, which may come from For products, end users or industry standards. The hold time of the test environment is generally short or modest (approximately 100 or 240 hours) and includes monitoring of a wide variety of characteristics or operational characteristics. These tests do not require determination of the long-term performance of the connector system, but determine if a serious problem exists. Normal quality qualification testing is only to solve the problems of prior art and known material systems.
Such testing involves a series of continuous tests conducted in a long-term exposure manner and typically focused on the electrical stability assessment of the connector system to determine the duration of the exposure to determine if it is within the expected life of the product or system. The time-dependent failure mechanism is sensitive. The determination of the (test) duration is dependent on experience and on the combined factors associated with test conditions/exposure times in the art.
In the traditional concept, the reliability test is complicated and rarely carried out on the connector. The test according to the operating environment and the functional requirements is clear in application. Reliability testing includes endurance testing for a certain period of time in the intended application environment, as well as a large number of data collection points for large sample sizes, which require intensive statistical processing of the collected data. Mroczkowski and Maynard elaborated on this aspect in more detail.
Reliability testing is economically viable only when considering the longevity of batches and applications. The determined reliability can only be applied to the relevant design features and production indices in the initial process. A change in design/material after determining the reliability level (or degree) of a product will make the reliability assessment ineffective.
