This is the second of three articles in Semiconductor Wafer Measurement for Increased Profitability. The first article in this series explains why disc geometry matters. The third article describes the benefits of using semi-automated, fully-automated, and manual systems for wafer metrology and inspection. Most semiconductor wafers are made of silicon, the second most common element in the Earth’s [...]

N/A led substrate sapphire thickness Displacement 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 [...]
Introduction In large motors and generators, the air gap needed to separate the revolving rotor from the stator should be as small as possible. This reduces the magnetizing power requirement which needs to be large enough to prevent contact between the two, despite manufacturing tolerances on their dimensions or movement resulting from mechanical deflection or [...]
Closed Loop, Non-woven Conductive Film Thickness Measurement and Control Solution Animation showing a system setup used to measure the thickness of thin conductive films such as electric vehicle (EV) battery electrodes. Description Learn how to measure EV battery plate thickness with MTI’s Digital Accumeasure, a high-precision capacitance [...]
Vibration and Balancing Systems: The Spectrum Plot Aviation / Aerospace Engine Balancing Vibration Description The Spectrum Plot – Types of Aircraft Vibration One of the least understood features of the PBS series of vibration analyzers is the spectrum function. The spectrum functionality is a more difficult [...]
Thickness Information of Composite Materials Industrial Thickness Information Of Composite Materials Thickness Description Introduction: Composite materials consist of two or more materials which include a substrate or base material such as paper, cotton cloth, or glass cloth along with a resin or adhesive such as [...]
