MTI Instruments Whitepaper: Capacitance Guide for Industrial Applications

Capacitance Guide for Industrial Applications This guide from MTI Instruments explains what you need to know about using electrical capacitance for measurement in industrial applications, including advanced manufacturing. Basic Principles Capacitance is the ratio of the change in an electric charge to the corresponding change in its electrical potential (i.e., voltage). Capacitors, components that that have the “capacity” to store an electric charge, consist of conductive parallel plates that don’t touch or connect with each other. Instead, these metal plates are electrically-separated by air or a layer of insulating material (i.e., the dielectric). MTI’s [...]

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 [...]

Cable Testing Applications

Cable Testing Applications Cable/Wire Testing Overview Cable testing is important in any industry that relies on cables for its operation. Cable testing is important for compliance and regulations because it helps ensure that cables meet the necessary requirements and standards set by regulatory bodies or industry organizations. These requirements are in place to promote safety, reliability, and performance, and failure to comply can result in legal consequences or penalties. Cable testing is important in various industries, including: Telecommunications: Cable testing is essential in the telecommunications industry to ensure that cables are properly installed and [...]

Silicon Carbide vs. Silicon in EV Power Electronics

Compare silicon carbide vs. silicon for electric vehicle (EV) power electronics and learn about SiC wafer measurement. As demand for electric vehicles (EVs) continues to grow, manufacturers are comparing two semiconductor technologies, silicon carbide and silicon, for power electronics applications. Silicon carbide (SiC) provides the high temperature resistance, low power consumption, rigidity, and support for smaller, thinner designs that EV power electronics need. Examples of SiC’s current applications include on-board DC/DC converters, off-board DC fast chargers, on-board battery chargers, EV powertrains, and automotive lighting for LEDs. According to Automotive World, SiC technology could also drive future EV innovations [...]

Measure Wafer Bow, Warp and TTV with Capacitance

The flatness of silicon wafers used to manufacture integrated circuits is controlled to tight tolerances to help ensure that the whole wafer is sufficiently flat for lithographic processing. To ensure your wafer manufacturing process is within tolerance, you need to measure the wafers being produced. Various measurement techniques exist to verify process tolerances and eliminate expensive scrap wafers. Non-contact capacitive sensing is a highly precise and cost-effective means to measure wafer flatness, bow, warp, and total thickness variation (TTV). MTI Instruments’ Proforma 300i and 300iSA systems use capacitance sensors to improve yields while reducing costs through better dimensional control of [...]

Target Material and Characteristics

Target Material and Characteristics Transparent/Opaque Targets There are a number of measurement systems that are capable of measuring a target that is opaque. When it comes to transparent targets, the measurement system being used must match the material of the target being measured. For example, if you’re attempting to measure plastic you should use a contact-type measurement system such as a micrometer. When performing a soft target measurement, such as film, a non-contact measurement system (such as a laser displacement sensor) should be utilized. Hard/Soft Targets Objects made out of hard material (such as a block of wood), would [...]
