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, [...]
ANGLE MEASUREMENT AND MONITORING
Introduction So what do sheet metal, speakers, and wine bottles all have in common? They represent the many angles and profiles that can be measured with laser sensor head. Angles: Numerous applications call for measuring angles such as sheet metal Press Brake applications. As the Press Brake bends the sheet metal, the controller reads the actual bend angle from the sensor head and can control under/over bending to reduce product waste and time. Sensor measurements can easily be interfaced with Press Brake control systems and allow an operator to: detect the bend angle monitor distortion of the punch and dies [...]
ADDING A DIGITAL PANEL METER TO MTI ANALOG OUTPUT PRODUCTS
How To Use Digital Displays with Analog OutputsMTI Microtrak 3 Lasers and some of our Accumeasure amplifiers such as the Accumeasure 9000 only have analog outputs. If you wish to add a digital display, then the Lascar Panel pilot © makes a nice cost effective (~ $110) addition – Fig 1. These Digital panel meters have both 1 & 2 channel display capability and the user can customize the display with a variety of interesting formats. The meter can operate off 4-30VDC which is compatible with the MT-3 power supply and the panel meter inputs can handle 0-10V which is compatible with [...]

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 [...]
NUCLEAR HEAT EXCHANGER VIBRATION
Power plants, particularly nuclear power plants, require heat exchangers to cool down the primary working fluid for the power plant. Excessive vibration can lead to cracking and premature failure of the heat exchanger. Problem: A major power plant company approached MTI looking for a sensor that could measure vibration of a heat exchanger assembly that was immersed under water. Additionally, the water could reach 250 F and up to 220 PSI; the probe had to be sealed with a gland at a bulkhead feed through area. Solution: MTI developed a special fiber optic probe based on the MTI-2125H probe configuration. The [...]

Exploring the Different Types of Aircraft Vibrations
There are two main types of aircraft vibrations: normal and abnormal. Normal vibrations regularly occur when an airplane is in flight and during takeoff and landing. These oscillating or reciprocating motions do not indicate potential defects with the aircraft or its engines and can be explained by routine operations such as flying through turbulence or extending or retracting the landing gear. With abnormal vibrations, a mechanical defect or condition is to blame. If this is not corrected, further damage and even catastrophic failure may occur. What are the causes of aircraft vibrations? The causes of aircraft vibrations include: engine [...]
