Bruker Corp., Billerica, Mass., reports that its Contour Elite 3D optical microscopes provide the high sensitivity and stability necessary for precision 3D surface measurements in applications and environments that are challenging for other metrology systems, such as R&D applications within the semiconductor and MEMS markets. Critical metrology includes measurements of film thickness and substrate roughness, as well as monitoring and validating key dimensional parameters such as RA roughness, pitch, width, and height.
Contour Elite systems are said to provide the best combined lateral and vertical resolution over the industry's largest field of view, with a sub-nanometer to greater than 10 mm vertical range. They also include high-fidelity imaging that reveals specific surface details—minute details that otherwise would be difficult or impossible to see.
Data segmentation based on color or grayscale information enables users to rapidly select areas of interest and collect critical metrology data from specific regions. This, combined with the ability to build a vivid graphic representation of a magnified zoom into the part, gives the user the ability to actually see the sample along with its true 3D topography, leading to better problem solving in engineered surface applications.
Because of its very high speed, Contour Elite's WLI technology is particularly well-suited as a QC/process monitoring tool where production volumes are pushed to ever higher levels. This latest generation of Contour 3D optical microscopes delivers a powerful combination of high-speed operation, an ability to function in factory environments, and uncommon accuracy making the Elite systems ideal for challenging applications that require critical surface inspections in the semiconductor and MEMS industrial markets.

Ultralight auto door made of aluminum, polymers, and electronic latch system
Source:
Magna International Inc., Troy, Mich., in cooperation with the U.S. Department of Energy and partners FCA US and Grupo Antolin, announces that the team has developed an ultralight door that achieves the project objective of 42.5% mass savings over an average current production door. This was developed in less than ten months, while keeping the cost within accepted industry parameters and providing a solution that applies to approximately 70% of the light vehicle market.
Magna built on its know-how from the development of the Multi-Material Lightweight Vehicle (MMLV) with the DOE and Ford in 2014, and took it a step further in creating a solution for this advanced ultralight door project.
A key innovation includes integration of Magna's SmartLatch electronic latch system. This eliminated the need for mechanical hardware and enabled the development of a unique carrier module with integrated glass guides and lift capability of a lightweight hybrid glass laminate, an industry first.
The door-in-white assembly makes extensive use of aluminum, which achieves approximately half of the total mass reduction of the door assembly. Overall, the project makes use of materials readily available today that can easily be made using existing manufacturing processes, without a significant increase in production costs or changes in body-shop infrastructure.
Grupo Antolin contributed its know-how in the design and manufacture of interior trim components to contribute to the significant mass reduction. The application of advanced molding technologies and polymers contributed approximately 7% to the total mass reduction.
The ultralight door development included intensive simulation efforts, passing all safety and durability testing in the process. The next steps include manufacturing full-scale prototype door assemblies, performance tests and safety tests to validate the design, with the goal of being available for use in production vehicles by the fall of 2020.

One Minute Mentor: Radio-Frequency Plasma
January 16, 2017
Source:
Glow-discharge plasma nitriding is carried out in nitrogen-hydrogen atmospheres at pressures in the range of 100 to 1000. At pressures below 10 Pa, the glow-discharge technique is not used, but plasma can still be generated by radio-frequency (RF) excitation, microwave energy, or electrons produced by a heated filament. These low-pressure plasmas diffuse through the treatment chamber with a large number of active species, which increases the nitriding efficiency. The uncoupling of plasma generation from the part being treated allows independent control of the energy and flux of ions against the substrate surface, and the temperature can be kept low.
In the RF plasma process, plasma is generated by high frequency, in the range of 13.56 MHz, is applied to an inductive antenna inside the vacuum chamber. The part is heated by heating the chamber and the working table with standard electrical resistance. One of the limiting factors for the commercial exploitation of the process is the high vacuum required, and the subsequent cost. The diagram shows a schematic of RF plasma equipment.
