Abstract

The primary limiting factor of the variable resistors presently available for operation in the low microampere range is output instability as a result of changes in contact resistance. These changes result from nonconductive films and dielectrics forming over time between the resistor element and wiper contact. The authors discuss a novel cermet technology that greatly reduces the effects of contact resistance, namely, recently developed Palirium system that improves output stability by creating a precious metal to metal contact point between the resistor's element and the wiper.<>

干电路用金属陶瓷厚膜技术的进展

目前可用于在低微安培范围内工作的可变电阻的主要限制因素是由于接触电阻变化而导致的输出不稳定。这些变化是由于电阻元件和雨刷接触之间的非导电膜和电介质随着时间的推移而形成的。作者讨论了一种新型金属陶瓷技术，该技术大大降低了接触电阻的影响，即最近开发的palrium系统，该系统通过在电阻器元件和雨刷器之间创建贵金属对金属接触点来提高输出稳定性。
