Multitest, a designer and manufacturer of final test handlers, contactors and load boards used by integrated device manufacturers (IDMs) and final test subcontractors worldwide, announces that it now offers a Kelvin Tutorial. A Kelvin contactor is required for economical testing of devices with measurements that are sensitive to contact resistance. A true Kelvin contactor completely eliminates contact-resistance errors from DC parametric tests.
Applying this excellent electrical solution to integrated circuit test (ICT) is a mechanical challenge. The targets that need to be contacted with two electrically-isolated, mechanically-independent probes are small and closely spaced (and getting smaller and closer). While implementing Kelvin contactors may be more expensive initially, in the long run they save money by cutting costs in high-volume production tests.
There are numerous Kelvin contactors available from different vendors and that use different technologies. The choice should be made carefully to best fit an individual company’s needs.
Multitest’s Kelvin Tutorial explains how a Kelvin connections work and when they are needed. Additionally, it includes some practical recommendations and examples. Download the comprehensive Kelvin Tutorial at www.multitest.com/KelvinTutorial.
