Signal Generator Simulates Eddy Current Probe
Signal Generator Simulates Eddy Current Probe Industrial, Power Generation, Automotive, Power Generation, R& D, Solar Simulation of Eddy Current Probe Gap, Amplitude, Displacement, Positioning, Thickness Description [Application Note 31218] Non-contact eddy current probes can be used to measure the position, or position change, of conductive targets in real time. Typical monitoring applications include shaft runout and/or vibration. Probe setup requires an oscillator demodulator circuit. This circuit converts the probe’s magnetic field readings into output voltages proportional to the gap between probe and target. Portal signal conditioning electronics are then used [...]
Capacitance Sensors Facilitate 3D IC Construction
Capacitance Sensors Facilitate 3D IC Construction Semiconductor, Research & Development 3D IC Construction Distance, Positioning, Displacement Description [Application Note 70518] To boost device performance, today's semiconductor and microelectronics manufacturers are building three-dimensional integrated circuits featuring vertically-stacked silicon wafers and dies. The rationale is simple. Exploiting the Z-axis avoids the power and footprint penalties associated with two-dimensional processes. Implementing the rationale, however, is not so simple. Going vertical requires coplanar surfaces to make contact with all pins, pads, and pillars. Problem Typically, manufacturers measure the angle and gap between two planes [...]

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 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 [...]
