Whitepaper: How to Work Safely with High-Voltage Test & Measurement Equipment
How to Work Safely with High-Voltage Test & Measurement Equipment Vitrek’s advanced 4700 High Voltage Meter and SmartProbes offer alternative to legacy approach to calibrating high-voltage systems. INTRODUCTION When working with high-voltage test and measurement equipment, electrical and test engineers strive to achieve the most precise readings possible while also maintaining a safe work area. Typically, they employ external probes such as high-voltage dividers, but these instruments come with drawbacks and are prone to errors. This whitepaper describes an alternative approach to calibrating high-voltage systems. The advanced solution comprises Vitrek’s 4700 High Voltage Meter for direct measurements [...]
WAFER MEASUREMENT – UNGROUNDED
Industry Semiconductor Applications Wafer Measurement – Ungrounded Measurement Type Metrology Description MTI Instruments Inc. has developed a thickness measurement device that eliminates the effect of varying target conductivity. Called the Push-Pull probe, it’s a unique version of the AccumeasureTM amplifier series. This special design provides accurate surface information for wafer bow and warp. Bow is the deviation of the center point of the median surface of a free, un-clamped wafer from the median surface to the reference plane. Where, the reference plane is defined by three corners of equilateral triangle. This [...]

TESTING CHARGE AMPLIFIER GAIN AND FREQUENCY RESPONSE WITH A SIGNAL GENERATOR
[Application Note 40518] Piezoelectric transducers produce small electrical charges in response to pressure. Their sensitivity, ruggedness, and stability at high temperatures make them an essential building block of many accelerometers and pressure sensors. Applications include turbine vibration measurement (accelerometers) and combustion dynamics monitoring (pressure sensors). Typically, the high-impedance charge output produced by a piezoelectric transducer must be conditioned and amplified before transmission across system cabling to the data acquisition and measurement instrumentation. This conversion is accomplished with a device called a charge amplifier. Problem Over time, a charge amplifier’s signal response can drift. Damage to the charge amplifier or associated [...]

THICKNESS INFORMATION OF COMPOSITE MATERIALS
Composite materials consist of two or more materials which include a substrate or base material such as paper, cotton cloth, or glass cloth along with a resin or adhesive such as epoxy, melamine, or silicone. To make a thermoset laminate, the base material is coated with the adhesive so that layers of material can be pressed under heat and pressure into sheet form. The Problem: Composite material thickness needed to be verified prior to forming or machining. Due to the size of the sheets typical measurement techniques were not suitable. A consistent method to accurately measure the board thickness [...]
