Case-In-Point: High-Accuracy Capacitive Thickness Measurement Optimizes Li-Ion EV Battery Plate Qualities
High-Accuracy Capacitive Thickness Measurement Optimizes Li-Ion EV Battery Plate Qualities EV Battery manufacturers need to measure EV battery plate thickness with a high degree of precision (repeatable <2um accuracy and resolution) to optimize manufacturing efficiencies while maintaining uniform cell capacity and minimizing waste. The MTI Accumeasure System provides an effective means of monitoring plate thickness achieving sub 2um accuracy with high repeatability Introduction The rapidly expanding demand for electric vehicles is driving advances in the production of rechargeable cells that comprise the first stage in the composition of EV battery packs. Individual Li-Ion cells are combined to form [...]

MTI App Note: 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 Introduction Figure 1. Simplified structure of a Li-Ion battery cell This white paper describes, in detail, how Non-Contact Measurement systems can be used to measure the thickness of the material used as anode and cathode plates in a rechargeable Li-Ion battery Cell. Figure 1 describes the elements comprising a Li-Ion battery cell. The cathode is comprised of [...]
Digital I/O ASIC Testing
Digital I/O ASIC Testing Customer Case A customer needs to generate stimulus to test his Application Specific Integrated Circuits and to capture response from that ASIC. The stimulus definition exists as an ASCII file with rows and columns of 1s and 0s. Each column corresponds to a different input pin of the ASIC and each rows corresponds to a different time tic (every 50 nanoseconds). The controlling baud clock runs at 10 MHz. The requirement is to record the digital response from the separate output pins of the ASIC as another ASCII file of 1s and 0s. Again, every [...]
Modernizing a Passive Sonar that has a Beam-Former with Digital Output
Modernizing a Passive Sonar that has a Beam-Former with Digital Output Customer Case The customer's requirement is to capture 10 signals, lasting 0.6 milliseconds each. 120 such signals arrive sequentially from a multiplexer within a beam-former. The clock rate is 2 MHz. The beam-former creates 120 beams and the raw digital data (underwater acoustic signal) from each beam is present at the output port of beam-former with a clock rate of 2 Mhz. At a certain time, we get the digital raw data of one beam. We plan to get 120 x 10 12-bit data records. That is, we [...]

MTI Application Note: How to Achieve <1um Accuracy When Measuring Roller Gap
How to Achieve <1um Accuracy When Measuring Roller Gap Roller Gap Measurement with MTI Digital Accumeasure Capacitive Probes 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. Problem How to measure the small gap between rollers to keep track of product thickness. Typically, it’s not possible to [...]
Neutrinos Study
Neutrinos Study Customer Case Neutrinos are said to be the most elusive and exotic particles in the universe. They are tiny neutral elementary particles that interact with matter via the weak nuclear force. Scientists are still trying to measure the mass and to characterize their properties. A customer who is studying neutrinos will be using photo multiplier tubes (PMT) coupled to a scintillating material to detect them. The PMT will produce a small electrical pulse when a neutrino is detected. These PMTs are located 2 Kilometers deep, in a mine located in Ontario, Canada. The customer is looking for [...]
GaGe Application Note: Creating a Data Link Signal Integrity Test Platform
Creating a Data Link Signal Integrity Test PlatformThis application note describes how a manufacturer of data links utilizes GaGe Instruments’ PC-basedhigh-speed data acquisition digitizers to perform production-level signal integrity testing. Data Link Device Testing The data link device under test (Figure 1) is characterized by comparing test signals that are input to the link with signals measured at the link output. Differences between these two test signals indicate a degradation by the link during transmission. The input and output test signals require sampling at 1 GS/s (GigaSample per second) with at least 14-bit vertical resolution. Both signals must [...]
