CAPACITANCE SENSORS FACILITATE 3D IC CONSTRUCTION
[Application Note 70518] To boost device performance, today’s semiconductor and microelectronics manufacturers are building three-dimensional integrated circuits featuring vertically-stacked silicon wafers and dies. The rationale is simple. Exploiting the Z-axis avoids the power and footprint penalties associated with two-dimensional processes. Implementing the rationale, however, is not so simple. Going vertical requires coplanar surfaces to make contact with all pins, pads, and pillars. Problem Typically, manufacturers measure the angle and gap between two planes to determine coplanarity. Bonding tool actuators rely on these angle/gap measurements to adjust components and make sure all device pins and/or solder balls reside on the [...]
MONITOR ROLLER GAPS AND PARALLELISM
Easy Roller Gap Measurement Ensures Calendering Success 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 Establishing a roller gap and checking for parallelism across roller width can be a slow and cumbersome procedure. Manual measurement requires multiple sized feeler gauges which can introduce errors. Misinterpreting feeler gauge drag, [...]

Compliance Testing of Harmonic Current Emissions According to IEC61000-3-2 and IEC61000-3-12.
Compliance Testing of Harmonic Current Emissions According to IEC61000-3-2 and IEC61000-3-12. Using the Vitrek PA900 Precision Harmonic Power Analyzer Introduction Compliance with electromagnetic compatibility (EMC) standards is mandatory for electrical and electronic equipment sold in many global markets. Among these, the IEC61000-3-2 and IEC61000-3-12 standards specify limits for harmonic current emissions of equipment connected to low-voltage public supply systems. These limits ensure that individual devices do not contribute excessively to harmonic distortion on the power grid, which can lead to overheating in transformers, nuisance tripping of breakers, and interference with other equipment. The Vitrek PA900 Precision Power [...]
Windshield Manufacturing
Industry Automotive Applications Oil Film Measurement Type Level Description In order to maintain proper profile and thickness within a glass furnace the extrusion plate spacing must be maintained at a predetermined gap. Unfortunately, due to process changes and temperature swings this gap can fluctuate significantly in short periods of time. This variation causes the glass thickness to change (check out our glass thickness measurement devices to accurately measure thickness), producing uneven temperature gradients and creating potentially weak glass panels. To control this critical parameter the manufacturing process requires automated active feedback [...]
GRINDING PROCESS
A cylindrical grinding process finishes most wheel spindle surfaces. It is essential that this grinding process leave a surface finish that is smooth and free of defects with minimal runout. No grinder produces a perfect surface. Grinder wheel runout, improperly dressed wheels and fixture vibrations can cause chatter on the spindle surface finish. Chatter is a series of microscopic, repetitive imperfections, or waves, in the surface of the material being machined. The required production environment sensor must have small spatial resolution, high frequency response and large standoff distance for easy loading and unloading of parts. Additionally, the measurement accuracy had to be [...]
Brake Rotors Thickness Variation
Industry Automotive Applications Brake Rotors Thickness Variation Measurement Type Surface Description Driving cross country or cross town, we give little thought to the operation or complexity of our vehicle braking systems. They only cross our mind when we absolutely need them; we never stop to think about the extensive design and testing that makes them such a lifesaver. Take the brake rotor for example. Under normal operating conditions it’s subjected to extreme temperatures and forces, which can cause rotor distortion and potential failure. To make certain it can withstand [...]
Oil Film Thickness Measurement
Industry Automotive Applications Oil Film Measurement Type Level Description A top marine engine manufacturer commissioned MTI Instruments to design and manufacture a non-contact sensor to measure the microscopic oil film layer between the engine cylinder wall and the piston ring. Engine testing is normally performed through a range of low RPM’s to high RPM’s (400- 6000) with piston linear speeds approaching 500 inches/second and at various torques. A measuring system with high frequency response and small sensor size was essential to keep engine machining to a minimum while not altering [...]
