Capacitance Sensing Provides Two Ways to Measure EV Battery Plate Thickness
MTI Instruments has released an application note that explains how to use capacitance to measure the thickness of the lithium battery plates in electric vehicles (EVs). Manufacturers need to check these plates for thickness before calendaring them together to ensure that the overall battery diameter is within specifications. In EV batteries, lithium ion compounds are applied to either a copper plate substrate (cathode) or an aluminum substrate (anode plate). These conductive plates are separated by a dielectric. MTI Instruments, a global supplier of precision measurement solutions, makes capacitance sensors that can measure thicknesses materials down to nanometers. Moreover, MTI [...]

Trends in High Resolution Sensors for Semiconductor Metrology and Inspection
High resolution sensors are supporting improvements in semiconductor metrology and inspection at vital points in the production process. Because the fabrication of semiconductor wafers may require hundreds of steps and weeks of manufacturing time, early-stage defects that go undetected can have costly downstream consequences. Plus, because semiconductor processing always requires a high degree of precision, advances in fabrication methods seem to require ever-finer measurements in a never-ending quest. Today’s metrology instruments are incorporating high resolution sensors for automated wafer inspection. Resolution, the smallest measurement that a sensor can reliably indicate, may be given in dimensional units such as nanometers [...]
Fiber Optic Sensor Measures Very Small Movements in Piezo Stacks
MTI Instruments, a global supplier of precision measurement solutions, has released an application note that explains how to measure very small movements in piezo devices that convert mechanical energy into electrical energy.

How the Aviation Industry Solves Vibration and Balancing Challenges
The aviation industry spends significant amounts of time and money on problems caused by engine vibration. Imbalance, the most common cause of engine vibration, happens because of bird strikes and other impacts, but also because of natural wear and corrosion that redistribute mass. In turn, out-of-balance parts can result in cabin noise, metal fatigue, and cracked turbine, fan, or compressor components. In the most extreme cases, catastrophic engine failure may result MTI Instruments, a worldwide supplier of precision measurement solutions, makes equipment for monitoring vibration levels and balancing rotors. For maintenance, repair and overhaul (MRO) crews who want to [...]
How to Reduce Inconsistent Wafer Measurements
How to Reduce Inconsistent Wafer Measurements Avoid 5 Common Mistakes That Destroy Wafer Measurement Accuracy You take pride in your work. You’re precise, accurate and depend on the right metrology equipment. Then why are your bare semi-conductor wafer measurements sometimes inconsistent? It may be something you’re doing (or not doing) — without realizing it. MTI Instruments discovered there are five common mistakes that engineers and users make with bare semi-conductor wafers. The “Five Mistakes Made When Taking Semiconductor Wafer Measurements” Tech-Brief details these all-too-typical errors that adversely impact measurements. [...]

Five Common Mistakes with Semiconductor Wafer Measurement
Semiconductor wafer measurement requires a high degree of precision. The right metrology equipment and inspection processes are important, but so is procedural consistency and attention to detail. If you’re not getting the results you want, it’s time to look beyond the measurements. With bare semiconductor wafers, users need to avoid these five common mistakes. Mistake #1 | Turning the Device Off Most users turn on metrology devices only when it’s time to use them. As soon as semiconductor wafer measurement is complete, the devices are turned off. This reduces electricity consumption but also introduces thermal instability that can cause [...]
Capacitance Probes: Five Things You Need to Know
Capacitance probes are non-contact measurement devices with a capacitance sensor inside a protective shell or housing. They use cables and connectors to integrate with amplifiers and are an important part of capacitance measurement systems. By using capacitance, engineers can measure physical parameters such as vibration, pressure, liquid levels, metal contamination, and seismic activity – just to name a few. There’s a lot to know about capacitance probes, but five key facts to understand. Capacitance probes are highly accurate and very stable. They’re better than older devices and competing technologies.
