Terminal measures of preventing defective insulation

In order to ensure the quality and reliability of the terminal, prevent the happening of the described earlier deadly fault, proposal according to the product technical conditions, formulate the corresponding filter technical requirements, carry out the following reliability test targeted to prevent failure. 1) Insulation materials inspection of raw materials quality had a great influence on insulators insulation performance. So for the choice of raw materials manufacturers especially important, should not blindly to reduce costs and loss of the material quality. Should choose metal material with good credit. And for each batch of material incoming check carefully check the batch number, material certificate, and other important information. Prepare material use traceability information 2) Insulators insulation resistance check to 2012, some factory assembly process into finished products after the detection performance, the results due to the insulation resistance is unqualified, insulator to the whole batch of finished product scrap. Reasonable technology should be in the insulator parts state is 100% for screening process, to ensure that the performance of qualified. Without reliable terminals, there is no reliable systems engineering. Dongguan precision electronic technology co. , LTD. Strict controls on terminal blocks of raw materials, materials used are imported or domestic high-quality materials. Mainly in copper, stainless steel materials are purchased from famous suppliers, effectively avoid the terminals in the raw material part material cause of failure. Failure and reliability is corresponding to the interconnected another two aspects of contradiction. Through the terminal reliability screening found various failure modes and failure mechanism, can lead to a lot of lessons and eliminate all kinds of hidden dangers, to improve the design, process, inspection and provide scientific evidence for use, it is also revise and formulate the important basis of terminal technology conditions. Looking for measures to prevent failure, transformed from failure to reliable, is the dongguan precision electronic technology co. , LTD. Is the ultimate goal of failure analysis.
