Thickness Gauge Measurement With Conductive Wafers and Thin Films
Thickness Gauge Measurement With Conductive Wafers and Thin Films Consumer Electronics Electronics Parts Profiling Thickness Description Using MTI's capacitive thickness gauge Proforma 300i with conductive wafers and thin films G = (a+b+t1+t2 ) Where G is the fixed gap between two probes When making the thickness measurement t2 can appear as t2 (film thickness) when it is a conductor, or 0 thickness when t2 is just air. So t2 will vary between the actual film thickness t2 if it's a conductor all the way down to 0 thickness if the [...]
Measuring Piezoelectric Properties with Fiber Optics
Measuring Piezoelectric Properties with Fiber Optics Research & Development Piezoceramic, 1-3 Pzt / Polymer Composite And Pvdf Film Amplitude Description Figure 4: Fiber Optic MTI 2100 Fotonic Sensor Introduction Researchers from the University of Arizona used the MTI-2000 Fotonic Sensor to measure the indirect piezoelectric properties (d33) and strain of bulk ferroelectric and thin film samples. The team then correlated these results with data acquired from direct piezoelectric effect measurement. By comparing data sets, the researchers concluded that the MTI-2000 provides a useful optical technique for measuring the [...]

Semiconductor Wafer Lapping and Displacement Measurement
Introduction This application note explains how MTI's Accumeasure technology was used with a lapping machine to measure displacement (wafer material removal) and determine the new semiconductor wafer thickness. Changes in electrical capacitance (displacement) were measured and then directly converted into a 24-bit digital reading to obtain precise digital thickness measurements. During lapping, a wafer of known start thickness is placed on a rotary lapping table. The backside of the wafer faces downward and toward a lapping surface that rotates and removes unwanted material. The amount of material that is removed varies by device type, and the entire semiconductor [...]

Capacitance Sensors Track Brake Rotor Thickness Variation
Capacitance Sensors Track Brake Rotor Thickness Variation Automotive, Aviation/Aerospace Brake Rotor Testing & Manufacturing Displacement, Amplitude Description [Application Note 51018] Today’s cars and trucks offer unprecedented fuel efficiencies and handling characteristics – thanks, in part, to vehicle lightweighting. Applied to all vehicle components, lightweighting lowers stress and strain to improve mileage and boost overall performance. In keeping with this trend, today’s brake rotors are thinner and lighter than those of just a few years ago. In addition, many feature cooling vents to further improve performance. These changes, however, reduce available [...]

Signal Generator Tests Charge Amplifier Gain, Frequency Response
Testing Charge Amplifier Gain and Frequency Response with a Signal Generator Aviation/Aerospace, Industrial, Power Generation, Research & Development Charge Amplifier Gain and Frequency Response Testing Amplitude (Acceleration, Vibration, Pressure) Description [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 [...]

These turbine sections feature separate shafts that produce unique tachometer signals. Gas turbine engines have multiple rotating sections generally referred to as the low pressure compressor (N1) and the high pressure compressor (N2). These turbine sections have separate shafts that produce unique tach [...]
Capacitance Probes Measure Gaps in Rotating Environments
Capacitance Probes Measure Gaps in Rotating Environments Textiles, Industrial Optimizing Performance of Rotating Cylinders Gap Description [Application Note 72518] Sensor environments are not always ideal. Across the various Gap sensor applications conditions may vary drastically. Some setups may have requirements of miniaturization, and others of wireless signal propagation. In rotating environments where cables cannot go, often there is a need for both. Problem Traditional sensing solutions can’t be used in environments requiring wireless propagation such as inside a rotating body. In these situations, the size and power requirements restrict the [...]
