Ultra-Low Temperature Elastomer

Greene Tweed’s (Kulpsville, PA) Fusion™ FKM 665, a new generation, ultra-low-temperature and chemical-resistant elastomer, was specifically formulated to meet and exceed the requirements of Aerospace Material Specification (AMS) 7379 and AMS-P-83461. With a temperature range of -70°F to 450°F (-57°C to 232°C), Fusion™ 665 achieves outstanding low-temperature performance without compromising high-temperature performance.

Fusion™ 665 was developed to overcome existing limitations of comparable materials, such as NBR, FKM, or FVMQ (Fluorosilicone).”

Drone Tracking System

Specialised Imaging (Pistone, UK) reports that its Lightweight Optical Motion Analysis (LOMA) system has been used to optically track an aircraft for several kilometers while simultaneously capturing the thermal signature of the aircraft over the same distance. The LOMA system accommodates large multiple camera payloads enabling high precision optical tracking of fast-moving aircraft, drones or projectiles even in environments subject to vibration, electromagnetic radiation or extremes in temperature and humidity.

Fitted with a Basler high-resolution optical camera with a 50mm Nikon lens and a FLIR X8500SC thermal imaging camera with 200mm lens, the LOMA system was used to track approximately 15 km of the plane flight. In poor weather or night time conditions the data from the thermal camera would be the preferred way to track the target.

Using independent motors, LOMA system users can control camera elevation (-20 to + 190°) and provide unlimited azimuth rotation using slip ring technology. Precision motor controls ensure smooth auto track functions to capture distant fast-moving objects with an angular accuracy of ± 0.002°.

Metal Printing System

nScrypt Inc. (Orlando, FL) is now developing a metals printing solution. Using its advanced, high-precision Micro-Dispensing capabilities, and building on its 2011 work in 3D printing metal parts in silver, nScrypt has developed a proprietary method for 3D printing titanium (Ti-6Al-4V) parts. Initial tests show exceptional densities of titanium coupons, with strengths in line with wrought titanium.

nScrypt’s proprietary process can be easily expanded to other metals, including stainless steels, Inconel, and copper, to provide unique solutions to a diverse range of industries. Additionally, nScrypt’s Factory in a Tool (FiT) systems have an integrated precision milling head (nScrypt’s nMill™) to perform finishing or polishing routines on critical areas of the part, with extremely high tolerance features, down to 2 microns (.00008”).

Aluminum Alloy F357 Powder

AP&C (Saint-Eustache, Canada), a GE Additive company, has announced that it will begin production of aluminum alloy F357 powder in Q1 2019 with customer deliveries expected from April 2019. Aluminum alloy F357 powder will be produced using AP&C’s proprietary Advanced Plasma Atomization (APA) at its recently expanded facility in Saint-Eustache, Canada. This new, automated plant offers a full production capacity of 1,000 tons.

Aluminum shares similar characteristics with titanium, and aluminum alloy F357 powder has the same quality signature as APA titanium powders, such as good processability, high flowability, high packing, low porosity and high purity, which are all required by the additive manufacturing industry to enhance performance and reliability of the aluminum printing process.

Aluminum F357 alloy is increasingly in demand from the aerospace and automotive sectors. It is known to have good weldability with high strength and toughness offering a good corrosion resistance and heat conductivity.

Low-PIM Coaxial Cables

Fairview Microwave Inc., (Irvine, CA) an Infinite Electronics brand, has released a new series of low-PIM coaxial cable assemblies in standard and custom lengths that are suitable for distributed antenna systems (DAS). The over 100+ standard configurations that make up Fairview Microwave’s new line of low-PIM coaxial cable assemblies deliver PIM levels of less than -160 dBc. These high-quality cables provide excellent VSWR and low insertion loss. They are 100% PIM and RF tested with the PIM results marked on the cables. These cables are constructed of flexible, lightweight UL910 plenum-rated SPP-250-LLPL RF coaxial cable which can operate in temperatures from -55°C to +125°C. They are offered with 4.3-10, 7/16 DIN, 4.1/9.5 mini-DIN, Type-N, SMA and QMA, many with right-angle connector options.

Custom-Engineered Linear Motion Platforms

Machine components such as bearings, encoders, and drive mechanisms are engineered and assembled directly on the granite base and bridge structures in an Integrated Granite Motion (IGM) system. Therefore, IGM systems are distinct from traditional stage-on-granite systems where discrete positioning stages and components are used in the system design.

Aerotech (Pittsburgh, PA) has an extensive history of designing, engineering, and manufacturing customized IGM systems. IGM systems can be designed with mechanical or air bearings, ball-screw or linear-motor drives, and a variety of feedback elements ranging from encoders to laser interferometers. Additional axes of motion, such as rotary, lift, or piezo stages, or even galvanometer scanners, can be integrated onto the IGM axes, all of which can be controlled from Aerotech’s A3200 unified control platform.

3D Inspection Software

Saki Corporation (Fremont, CA) introduced Saki Self-Programming Software, the first self-programming software for solder paste inspection (SPI) and automated optical inspection (AOI) equipment. Saki Self-Programming (SSP) software, installed on Saki's 3D SPI and 3D AOI systems, makes programming fast, easy, and doesn't require any special programming skill or training. All you need is the Gerber and centroid CAD data. The software does the rest.

Saki Self-Programming is a seamless system that doesn't require DFM software. It combines technology that captures complete height and XY data and images while simultaneously scanning multiple fields of view. The ability to select from over 300,000 components from Saki's Golden Library offers unlimited possibilities. In a matter of minutes, with just a few clicks, SPI/AOI inspection data can be programmed automatically, using a defined set of standards and criteria, such as naming, orientation, and parameters, as those recognized by IPC standards for AOI and SPI systems. This removes the programming discrepancies and variations that arise when programming is done by different programmers.
