Ball Bearings

MRC Bearings Services (Kulpsville, PA) offers the R Series inch-sized stainless ball bearings for small shaft diameters. The single-row, deep-groove radial conrad-type bearings carry radial and thrust loads in either direction at high speeds. Bore sizes range from 1/8 to 1 ½", and open, shielded, and sealed bearings are available. Basic radial dynamic load ratings range from 70 lbf to 3,780 lbf and basic radial static load ratings range from 27 lbf to 2,650 lbf, depending on type. The bearings are supplied with pressed steel cages. Two-piece riveted machined phenolic or bronze cages are available.

Motorized Stages

Prior Scientific (Rockland, MA) has added patent-pending Intelligent Scanning Technology (IST) to its Prior ProScan™ II H101A, H107, and H117, 4 × 3" scanning stages. IST allows each stage to be pre-programmed with a unique set of operating characteristics to that particular stage. The technology also allows the controller to periodically interrogate the stage and make adjustments to maintain orthogonality and metric accuracy.

Distributed Intelligence Drives High-Energy Laser Manufacturing

Historically, high-energy (Joule-class) nanosecond YAG lasers have been confined primarily to laboratory research facilities and government labs. System designs were unique for each facility and the low number of systems worldwide made the learning curve for system improvement slow. It is only in recent years that the maturity of the technology has reached a state that makes it possible to consider these lasers for industrial applications.

DFM Your Device? Simulation Is the Answer

Design for Manufacturing (DFM) has taken off like a rocket in the electronics industry in recent years. Performing process and device simulations on CMOS transistors in a DFM flow have proven to be important in shortening the design cycle and reducing the production cost by improving yield. These are the key elements to why DFM mans the gate to the success of semiconductor foundries and companies.

HBLEDs: Tackle Your Silicone Packaging Problems

It is widely known that the light emitting diode (LED) R&D and commercialization community is striving to produce higher power, bright-white-light LEDs. From both a temperature and UV-resistance standpoint, silicone is rapidly becoming the material of choice for the next-generation chip encapsulant. But as LED manufacturers look to employ silicones in their manufacturing processes, they must be aware of potential problems. Cure inhibition can lead to unacceptable variations in the manufacturing process and thus, the finished product. This article takes a brief look at the benefits of using silicones in high-brightness LED (HBLED) applications, with a focus on potential production floor issues and their solutions.

Color Cameras

PPT VISION (Minneapolis, MN) has added the IMPACT™ T28 and the IMPACT™ T24 to its line of IMPACT T-series color cameras designed for inline industrial vision applications. The IMPACT T28 provides a 1,600 × 1,200 pixel resolution and is suitable for color verification, label inspection, and real-time part sorting. The IMPACT T24 is designed for applications requiring resolution imaging of 1,024 × 768 pixels. Both cameras are suitable for quality verification, and contain an on-board image processor and real-time I/O and Ethernet communications. The cameras are supported by Inspection Builder software, a machine-vision application development package that uses icon-based programming and inspection algorithms for pattern matching, blob analysis, sub-pixel gauging, and character inspection.
