Polyclad Laminates Inc., a business of Cookson Electronics, has introduced Polyclad 250HR laminate and prepreg materials. With a 150°C glass transition temperature (Tg) and 350°C decomposition temperature (Td), is suited for mid-Tg, lead-free applications. The CAF-resistant materials maintain low expansion rates while retaining FR-4 processability.
 
Used in the manufacture of automobiles, computer servers, telecommunications devices and other electronics, said to offer exceptional IST thermal performance and reliability. Contains a multifunctional epoxy resin technology for reduced CTE.
 
Compatible with all commonly used FR-4 fabrication process techniques. Mechanical, chemical and moisture resistance meet or exceed the performance of competitive FR-4 material. Is laser fluorescing and UV blocking for maximum compatibility with AOI systems, optical positioning systems and photoimageable solder mask imaging.

A major upgrade to the CR-5000 enterprise-wide PCB design suite of tools includes 44 productivity enhancements in schematic capture, layout and simulation.

Version 8.01 is aimed at designers of high-complexity boards that use extreme miniaturization technologies such as embedded passives, flex circuits, high-density interconnects and FPGAs. Capabilities include RF design, design re-use and design partitioning  with core design strengths that meet the requirements of consumer and high-tech electronics applications. Built on the design structure and methodology of version 7.

Enhancements to schematic capture and analysis module include a net connect view, the ability to import and export net label and pin information in CSV format, new fault analysis functions and a property viewer that can be used during symbol re-load. The upgrades to the Board Designer placement and routing module mean that users have use of automatic area correction functionality, benefit from even deeper integration with mechanical CAD and can achieve more consistent star-point connections. The board layout tool can space tracks automatically based on the electrical potential difference between them, and has support for multiple bond wires.

Vibration Isolation Mounts are ideal when designing or retrofitting sensitive OEM equipment where external isolation is not desired or is not suited to the application. Available in a variety of shapes and sizes with load capacities ranging from 200 to 20,000 lbs, and standard heights of 4", 6", 12" and 24".
 
Provide vertical and horizontal vibration isolation with low natural frequencies, automatic leveling and height control to within 0.005", and internal damping for improved stability. Have a standard blue polyurethane finish and are Class 100 cleanroom compatible.
 
Offered in active and slave configurations. Active mounts use the VIBRALEVEL Air Servo Valve to feed or bleed air from the mounts to maintain preset "zero deflection" and compensate for load changes. Slave mounts do not have Air Servo Valves but are controlled by one of the active mounts.
 
Options include a damping tank, a portable air compressor and a white epoxy-powder-coat finish for Class 10 cleanroom compatibility. 
 
Can also be used for steppers, laser trimmers, automated wafer inspection, profilometers and surface-measurement instruments.
