This requirement is typically not well defined on the fabrication drawing and that leads to misleading conclusions by the fabrication house. 4-Wire Kelvin testing has been around for many years but using this type of measurement on bare PCB's is a relatively new requirement. The requirement for...

Fig. 1 Simple resistance measurement Fig. 2 Resistance measurement with Kelvin connection A MOSFET is a device controlled by the voltage between the gate and source. When the drain current is large, the same phenomenon as shown in Fig. 1 occurs when the voltage is applied between the...
4-Wire Kelvin testing has been around for many years but using this type of measurement on bare PCB's is a relatively new requirement. The requirement for PCB 4-Wire Kelvin testing was originally requested by digital commercial OEMs in the US with the aim to set out to improve the overall...

But the aesthetic sphere of the mind, its longings, its pleasures and pains, and its emotions, have been so ignored in all these researches that one is tempted to suppose that if either Dr. Ferrier or Dr. Munk were asked for a theory in brain-terms of the latter mental facts, they ...
2Temperature measurement 2Network cable testers 2Alignment tools 9Calibration tools 2Fluke software It’s the process of testing a measuring instrument to ensure it operates within acceptable accuracy ranges. What does calibrating mean in electronics?
Measurement of any quantity is expressed in 2 parts— a numeric value and the specific unit. The following are the most measured quantities:Length Weight Volume Time Temperature SpeedMetric and US Standard are the two main systems of measurement. The table below summarizes the units of measurement...
