  • Theory and Application of Precision Ultrasonic Thickness Gaging
    permit quick and reliable measurement of thickness without requiring access to both sides of a part. Calibrated accuracies as high as ±2 micrometers or ±0.0001 inch are achievable in some applications. Most engineering materials can be measured ultrasonically, including metals, plastic, ceramics
  • X-MET8000 Series for rapid, on the spot coating thickness measurement
    Coating, or plating, is the deposition of a metal on an object's surface to give this object specific properties: coatings can be decorative, prevent corrosion, improve solderability, increase hardness, reduce friction and wear, and more. To ensure that the thickness of the coating applied
  • Optimised Metal Strip Measurement
    , the thickness profile of the metal strip is an important feature. There are many different approaches for measuring the thickness profile. A very interesting solution is provided by Micro-Epsilon, a sensor and system manufacturer from Ortenburg.
  • Metal-faced sensors
    face. Pepperl+Fuchs recommends that a stainless-steel metal cover be at least 0.4-mm thick. That thickness of metal requires special oscillator-and-coil circuit designs to "see through " the metal cover to detect the target metal beyond. Another problem: The addition of metal faces to inductive
  • How Expanded Metal Is Made
    Expanded metal is made by a process of slit and stretch. A precision die slits and stretches the material in a single operation. The material is then processed through a set of rollers which adjusts the final thickness. The shape, form and number of openings are dictated by the particular tool used
    This procedure is used to measure the dry film thickness of coatings applied to magnetic or non-magnetic metal substrates using a magnetic induction or eddy current type electronic gauge, respectively.
  • Design Considerations for Metal Injection Molding
    Advanced manufacturing: Design Considerations for Metal Injection Molding Metal injection molding (MIM) produces relatively small (150 to less than 30-gm), complex, net, or near-net parts which can include features such as holes, radii, logos, and text. Moreover, MIM can make such parts for half
  • Surface Finishing Tutorial: Metal Etching & Chemical Milling
    Chemical milling is also called "Chemical contour machining", and is a metal milling technique by utilizing chemical etching process. With this technique the etching depth is limited to the thickness of the material to create three dimensional features, unlike through etching techniques.
  • Solid Edge Sheet Metal White Paper (.pdf)
    If your company designs sheet metal parts, it faces a series of unique challenges. Although parts are typically designed in their "formed" state, they begin as a flat plate. As a result, manufacturability becomes a critical aspect of every feature making up the finished part. Add to this, the need
  • Powder Metal Designs Win PowderMet 2009 Awards
    and appliances, hand tool and recreation, and aerospace and military categories. The automotive-engine grand prize went to a powdered-metal (PM) steel manifold developed by , Carson, Calif., and Capstan's customer , Bloomfield, Conn. The manifold, assembled with a solenoid into the valve-train of a heavy-duty
  • Thickness of protective coatings on wristwatch dials
    metal, some even set with diamonds and other gemstones. But what most of them have in common is a dial: a signature feature of any watch, and a very delicate part exposed to significant stressors.
  • High Precision Thin Metal Film Measurement by Optical Transmission
    , the ohmic metal needs to have each of the constituent layers deposited precisely. In these applications, thickness variations of as little as 5Å will result in detectable device performance shift and probe yield loss. A typical E-beam evaporator employs a crystal monitor for deposition control and film
  • Analysis of Barrier Metal Layers of SI-Devices (HD-2000 5)
    of devices or for protecting metal wirings from chemical reactions with corrosive gases. These layers are composed of Ti or TiN and they are required to have a uniform thickness.
  • MICRO: Product Extras (Jan '2000)
    A system for measuring copper CMP process parameters on-line in the polisher has been developed by Based on the company's NovaScan technique, the system measures metal loss, metal thickness, and residues inside the die on actual structures. The technology will enable IC manufacturers to shift
  • Copper Brazing in Ceramic-to-Metal Assemblies for Hermetic Applications
    The use of ceramics with traditional Molybdenum/Manganese and Nickel plated metallization for hermetic applications is common, however, brazing with Copper as the joining material has not been highly recommended. This present research was done to examine the effects of the Nickel thickness
  • Introduction to Eddy Current Testing
    and service environments that require inspection of thin metal for potential safety-related or quality-related problems. In addition to crack detection in metal sheets and tubing, eddy current can be used for certain metal thickness measurements such as identifying corrosion under aircraft skin, to measure
