Capacitance Sensors Track Brake Rotor Thickness Variation
[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 braking surface, forcing automotive engineers to consider alternative materials and designs. Problem Because the extreme temperatures and forces generated during braking can easily lead to rotor [...]
LED SUBSTRATE THICKNESS
Industry Semiconductor Applications Photolithography Using Capacitance Sensors Measurement Type Positioning Description Remember that old acronym, GIGO? Garbage in garbage out, it can apply to raw materials as well as programming. Sapphire wafers need to be of a certain quality to ensure maximum yield. Excessive TTV, Bow, and Warp lead to premature LED failure. LED manufacturers need to inspect incoming wafers. Wafer producers also need to check and control TTV, Bow and Warp. The market for sapphire wafers, driven by the growth in LED manufacturing, is booming. While the price [...]
ADE/KLA Ultra Gage 9500 Replacement Guide: Issues and Opportunities For Companies Considering the Proforma 300iSA as a 9500 Replacement
Technical Review: This guide is based on verified specifications from semiconductor equipment manufacturers, industry standards organizations (ASTM/SEMI), and equipment documentation. All technical claims are referenced to authoritative sources. If you're seeking information regarding the ADE UltraGage 9500, KLA UltraGage 9500, or KLA Tencor 9500, you've likely discovered that this wafer metrology system is no longer in production. As support continues to decline, semi facilities operating these systems face a critical challenge: determining the most suitable replacement solution. The MTI Instruments Proforma 300iSA represents a direct and modern alternative, offering not only a comparable replacement but also substantial improvements over [...]
Thermal Expansion on Automobile Engine
For years the sole purpose of the oil pan was to act as a reservoir for the engine lubricant. Some modern engines now utilize the pan as a structural component. It is machined from a rigid steel or aluminum casting and designed to support the lower portion of the crankshaft bearings and rear main seal. This development has introduced a potential problem area that must be analyzed. As engines go through heating and cooling cycles it is essential that the engine block and oil pan expand and contract at nearly the same rate. If not, stresses can be introduced [...]

PIEZO STAGE POSITIONING
Industry Consumer Electronics Applications Piezo Stage Measurement Type Positioning Description Positioning stages using piezoelectric stack actuators (PEA) have very high resolution. However, it is difficult to achieve precise dynamic motion tracking using traditional linear controllers such as PID due to the inherent hysteresis nonlinearity of piezoelectric materials and the phase lag associated with such controllers. Capacitance Sensors are ideal for measuring the actual piezo stage position and correcting for the inherent nonlinearity through closed loop feedback. They have the stability, bandwidth and high resolution needed to do the job. [...]
WAFER QA/QC AFTER SLICING AND POLISHING
Industry Semiconductor Applications Wafer Qa/Qc After Slicing And Polishing Measurement Type Surface Description When wafers are sliced up with wire saws, they are measured to make sure they are within the specified thickness, with minimal bow, warp, and TTV. After initial measurement, they are sorted and sent for polishing. Since polishing removes material and smoothes out the rough surfaces they need to be measured again to ensure they meet thickness guidelines and quality standards. Solution: MTI Instruments manufactures multiple systems to perform thickness measurements. From semi automated Proforma 300SA to manual wafer [...]
