Multicore TTC-LF allows soldering irons to be re-tinned, even when conventional methods such as sponges, pads or rosin-cored solder wire are not effective.

Applicable for lead and lead-free applications, the product is a small block of electronics lead-free grade solder powder and flux formed into the shape of a thick disk. For cleaning and de-wetting soldering irons, users need only wipe the tip of the soldering iron gently across the surface to produce local melting and then wipe as normal on a damp sponge to ready the iron for re-use.

Benefits include minimal residues, activators that thermally decompose into inert components and the ability to clean heavily oxidized metal surfaces such as copper and iron plated soldering tips.

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.
