在无线网络通讯设备产品维修这个领域内,产品的返修率高,系统的不稳定仍然是迫在解决的问题。影响产品不稳定的因素很多,通过对无线通讯产品维修多年的经验出发,基于对产品的故障分析、客户的现场反馈情况,结合4M1E理论分析一些影响网络通讯产品可靠性的隐患因素,只有发现这些隐性因素并提出一些改进措施,并通过跟踪大量维修的产品加以实践,从而达到降低返修率,提高系统的可靠性。 In the field of product maintenance of wireless network communication equipment, the high repair rate of the products and the instability of the system are still problems that are forced to be solved. There are many factors that affect the instability of the product. Based on years of experience in the maintenance of wireless communication products, based on the failure analysis of the products and customer feedback on the site, we analyze some hidden troubles that affect the reliability of network communication products based on the 4M1E theory. Implicit factors and put forward some improvement measures, and by tracking a large number of maintenance products to practice, so as to reduce the rework rate and improve system reliability.
