Case-In-Point: Step Height Measurement (Thickness) of Copper Foil or EV Battery Film on a Roller Rig
Step Height Measurement (Thickness) of Copper Foil or EV Battery Film on a Roller Rig Leverage MTI Instruments’ digital Accumeasure system to measure the thickness of the material used as anode and cathode plates in rechargeable Li-Ion battery cells Many roll-to-roll finishing processes typically use a calender, or series of hard pressure rollers, to deliver smooth, high-quality products of plastic, textile, or paper (Fig 1). Ensuring a consistent material thickness, however, depends on the ability to monitor, and maintain, a precise gap between rollers. This application note describes a quick and easy means for roller gap measurement. Introduction [...]
Whitepaper: Three Vibration/Balancing Solutions for the Aviation Industry
Three Vibration/Balancing Solutions for the Aviation Industry MTI Instruments Offers a Variety of Solutions for Commercial, Regional & Military Jet Engine Balancing Applications Introduction Throughout the aviation industry, whether commercial or military, jet engine vibration is an everyday concern. Maintenance, repair, and overhaul crews worldwide are tasked with monitoring aircraft engine vibration to ensure flight safety and efficient service. Gone unchecked, jet engine vibration can be the catalyst for any number of problems, from minor annoyances such as cabin noise to undue parts wear. In the most severe cases, an out-of-balance turbine could lead to catastrophic failure [...]
New Video from MTI! Closed-loop System to Monitor and Control Conductive Film Thickness During Manufacturing
Closed-loop System to Monitor and Control Conductive Film Thickness During Manufacturing This animation demonstrates how Accumeasure with capacitance probes can be used as a solution to measure and control conductive film thickness in a production line where these measurements can be fed back to a controller which adjusts the roller(s) to increase or decrease the gap to keep the film’s thickness within specification. The MTI Instruments Capacitive system has greater than 100 nm resolution and 1um accuracy. This solution is appropriate for measuring the following: EV battery plate thickness Non-woven conductive material thickness Conductive film thickness Roll-to-roll conductive [...]
Safety Recommendations for Setting Up a Hipot Testing Workstation
Hipot testing is necessary for ensuring the electrical safety compliance of electronic equipment. However, testing the voltage on commercial equipment can result in errors and even death if the operators have not been properly trained on the importance of establishing a safe testing environment. Before any tests are performed, operators should be thoroughly trained on the effects of electrical currents on the human body, the importance of safety interlocks, and how to program the necessary tests and store them in memory. If operators lack the appropriate training, setting up a safe hipot testing workstation would be for naught. After prioritizing [...]

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 [...]
