led substrate sapphire thickness
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 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 has come down significantly since 2011, the size of the wafers [...]
Dynamic Measurement of Armature Gaps
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 looseness in supporting bearings. The gap should also be uniform; a non-uniform gap causes increased noise and vibration. Since large generators and motors are usually quite expensive, it's advisable to monitor the gap to prevent catastrophic failure should the rotor or stator expand due to [...]

Vibration and Balancing Systems: The Spectrum Plot
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 function to understand, but once mastered, technicians can quickly develop an extremely in-depth understanding on what is going on in an engine during a test. Figure 1, below, shows a basic spectrum from the PBS system. On the x-axis is frequency, measured in Hz (per second). [...]
Ultrasonic Tissue Characterization
Ultrasonic Tissue Characterization Customer Case This customer's application is Ultrasonic Tissue Characterization. Their ultrasonic sensors transmit 16 signals. The customer's requirement is to capture 512 points on the 16 channels, average them together, and then store the data in a buffer, with the system running continuously. They would like to be able to update the average buffer and recapture data as fast as possible. They would then like to log the data to disk or process the data and display an image on the screen. Since the signals coming in from their ultrasonic sensors are very weak, the customer [...]
Thickness Information of Composite Materials
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 epoxy, melamine, or silicone. To make a thermoset laminate, the base material is coated with the adhesive so that layers of material can be pressed under heat and pressure into sheet form. The Problem: Composite material thickness needed to be verified prior to forming or [...]
Digitizing Ultrasonic Signals
Digitizing Ultrasonic Signals Customer Case The customer has an ultrasonic signal that he wants to digitize with either 8 or 12-bit resolution. The sampling rate required for this application is a minimum of 16 MSPS (20 MSPS is acceptable). Finally, the data must be acquired for a full 10 seconds. The data is not coming in continuously: it is arriving in bursts one millisecond apart (PRF = 1 KHz). For each trigger the customer wants to capture approximately 200 us of data. Once this data is acquired, the customer wants it saved to the hard drive as a standard [...]
