3D Integrated Circuits Use Capacitive Sensing to Ensure Coplanarity
Three-dimensional (3D) integrated circuits (ICs) feature silicon wafers and dies that are stacked vertically for improved device performance. By using the Z-axis, 3D ICs can overcome the power and footprint limitations associated with two-dimensional (2D) integrated circuits. Yet 3D ICs need coplanar surfaces to contact all of the pads, pins, and pillars. To determine coplanarity, semiconductor manufacturers measure the angle and gap between two planes. Bonding tool actuators use these measurements to adjust components and ensure that all device pins and solder balls reside on the same geometric plane. This process, active parallelism compensation, promotes proper bonding without residual [...]

Engine Vibration and Balancing Principles
What do you think when you’re flying home, cruising at 30,000 feet and the drinks have just been served? Our engineers think about the ripple in the glass. That ripple signals vibration and is an indication that the engine may be in need of a balance. The MTII’s PBS-4100+ Series Turbine Vibration Analyzer/Balancing System was developed to ensure that Turbine engines run as efficiently as possible. Excessive vibration is detrimental for a host of reasons: energy intended for useful output is instead expended on the vibration vibration manifests as acoustic energy (noise), again wasting otherwise useful energy excessive [...]

Fiber Optic Sensor Principles
The Fotonic Sensor™ is a non-contact instrument, which uses the fiber optics lever principle to perform displacement measurement, vibration analysis and surface-condition measurements. The Fotonic Sensor transmits a beam of light through a flexible fiber-optic probe, receives light reflected from a target surface, and converts this light into an electrical signal proportional to the distance between the probe tip and the target being measured. A simplified example of the fiber optic principal is shown in Figure 2. The output signal voltage from the fiber optic sensor is then used to determine position, displacement, vibration amplitude, frequency and waveshape of a [...]
