新型接触电阻检测仪的应用

Application of New-type Contact Resistance Tester

互连器件接触电阻检测,一直是系统连接后判别每个接点接触是否可靠良好,必须解决的实际问题。随着高密度、小型化的互连器件在电子电气设备上的广泛应用,如何解决互连器件接触电阻的在线自动检测,己成为确保互连器件质量和可靠性的关键。文中在详细阐述接触电阻检测原理的基础上,介绍了新研制的TDO-MCR-07A多接点接触电阻检测仪特点、检测方法和主要技术参数,以及连接电脑和工装组成自动检测系统后,成功用于保险丝盒接触电阻自动检测的实例。

The testing of contact resistance of FPIC has aJways been a practical issue that needs solving to discriminate whether each contact point is good and reliable or not once the system is connected. With the wide range applications of high-density, compact FPIC in electrical and electronic equipment, how to solve the auto test of contact resistance of FPIC, has become a key factor to ensure the quality and reliability of FPIC devices. On the basis of detailed presentation of the principle of contact resistance testing, this article introduces the characteristics, testing methods and main technical parameters of newly developed TDO-MCR-OTA multi-point contact resistance tester. As well, it introduces a successful application example in contact resistance auto-testing in fuse box when connecting computers and frock to constitute auto-testing system.
