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 [...]

Whitepaper: Semiconductor Wafer Measurement for Increased Productivity
Semiconductor Wafer Measurement for Increased Productivity This three-part article describes how manufacturers leverage capacitance-based inspection systems for semiconductor wafers. The article reviews best-practices, consequences of failing to inspect semiconductor wafers and benefits of using semi-automated, fully-automated and manual systems for wafer metrology and inspection. Part 1: Why Disc Geometry Matters in Wafer Production Semiconductor wafers are cut from cylindrical silicon crystals, or ingots. The flatness of these disc-shaped wafers is controlled to tight tolerances to ensure that the entire wafer surface is suitable for integrated circuit (IC) production. If disc geometry is out-of-spec [...]
The Cost of Failing to Inspect Semiconductor Wafers
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 crust. Yet, silicon’s abundance does not mean that wafers are inexpensive. The pure form of silicon that’s used in semiconductors does not occur naturally and must be refined and mixed with a dopant that alters material properties and electrical characteristics. Silicon ingots are formed, wafers [...]

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 [...]
Arbitrary Ultrasonic Generator
Arbitrary Ultrasonic Generator Customer Case Ultrasonic generation pulses must be varied to accommodate different types of ultrasonic transducers. General-purpose highly damped contact transducers are usually excited by a wideband, spike-like pulse that is provided by many common pulser/receiver units. Lightly damped transducers, used for example in high power generation, require a narrowband tone-burst excitation from a separate generator unit. Sometimes, even the same transducer will be excited differently, for instance, to study the dispersion of a material's ultrasonic attenuation or to characterize ultrasonic transducers. In order to construct a flexible ultrasonic generation unit, engineers have excited transducers with a [...]
