Contact resistance, or CRES, is one of those problems that most engineers prefer not to think about until it’s staring them in the face. For years, it could be managed quietly with routine probe card ...
In Episode 27 of “EC&M Tech Talk,” Randy Barnett, a journeyman electrician, inspector, author, trainer, and electrical safety expert, reviews the purpose and methods used for measuring the quality of ...
In the first part of this series on the highs and lows of resistance measurements, I discussed the basic principles for making two- and 4-wire resistance measurements for measuring resistances of less ...
Download this article in PDF format. Proper wiring and probing/contacting are critical to making successful measurements. When testing cells or batteries, using good engineering practices is important ...
Don�t heap all the blame for a wrong measurement on the DMM. There can be several less obvious sources of the errors. Testing assemblies and components usually includes checking the continuity of ...
In today’s advanced packages, however, resistance no longer resides primarily inside transistors or neatly bounded test ...
