Failure Analysis of High Speed Transmission Differential Cable Assemblies

随着电子技术的飞速发展和不断提高,产品电装设计对电子设备内的电缆提出了更高的要求。电缆组件的制造工艺性也较以前变得更加复杂和多样,而电缆组件的装配质量则是影响整机电气可靠性的关键因素之一。以整机电装中最关键的高速传输差分电缆为例,先介绍了高速传输差分信号技术在电子产品中的应用,然后列举了差分电缆在日常工作中常见的一些失效案例,并对其进行了分析,提出了差分电缆制作过程中的关键点及其控制建议,为生产高可靠性产品提供了有力的工艺保障。

With the rapid development of electronic technology and continuously improving products, cable electrical in stallation design for electronic equipment s was put forward higher requirements. The manufacturing process of the cable as- sembly than in the past has become more complex and diverse, and the assembly quality cable assembly is one of the key fac- tors affecting the electric reliability. Therefore, the key difference of high-speed transmission cable for example based ma- chine electric equipment, first introduced the High-speed transmission differential signal technology in electronic products, and then listed some failure case difference cable common in everyday work, and has carried on the analysis, proposed the key points of difference cable in the production process and control, providing technical support for high reliability products.
