Due to the parasitic effects mentioned earlier, you will need to carefully select asubstrate materialand design your stackup. Thedielectric constantof your substrate will affect the geometry required to produce a transmission line with specific impedance and will affect the impedance of the po...
Partial Discharge Measurement One method to measure partial dis- charge consists of a narrow band test method. VDE uses narrow Ck = COUPLING CAPACITOR DUT = TEST DEVICE Z = RESISTOR OR FILTER Zm = IMPEDANCE OF THE MEASURING CIRCUIT (LC RESONANCE CIRCUIT) Figure 4.9.3: Narrowband Partial ...

It takes longer for it to diffuse, exactly. And that makes the intermetallics thickness very, very small. And overall the reliability increases because every time people measure, okay, what is the intermetallic thickness at day zero? And what is intermetallics thickness five years from now, 10 ...
• ESD Protection Measure#2: ESD Protection Device To largely stop static electricity from being generated and to release the existing static electricity, ESD protection devices should feature sufficient conductivity and be capable of controlling the speed of ESD leakage to avoid static electricity ...
The main function of a GIS substation is to switch, separate, transform, measure and distribute electrical energy in power systems. The main feature of a GIS device is the use of SF6, an inert gas with exceptional insulation properties, and chemical and thermal stability. ...
In this groundbreaking book, Bill Price and David Jaffe offer a new, game-changing approach, showing how managers are taking the wrong path and are using the wrong metrics to measure customer service. Customer service, they assert, is only needed when a company does something wrong-eliminating ...
[Image 1] displays the junction box which houses my machine's Coolidge tube, its lead shield, the voltage multiplier and a 1.8 billion ohm resistor to measure the anode voltage. A 90kV this resistor will leak the 50uA needed to fully deflect a galvanometer. The thickness of the box’s ...
The Fr-4 material is a popular PCB base material due to its low cost and versatility. It comprisesfiberglassweaved to a thin, cloth-looking sheet enclosed with a fire-resistant epoxy resin. We measure the Fr-4 standard PCB thickness in millimeters or inches, usually from 3″ to 10″. Ho...
The housing also influences the PCB antenna's tuning frequency, for this reason, it is always recommended to measure the RF performance of the application in the final product configuration. 22/26 AN2972 Rev 9 AN2972 From design to production Figure 26. Impact of housing/packaging material o...
