INDEX

Designed to provide maximum cable protection and support, OnTrac includes side wall curves that keep cables secure within the tray through each turn, while an open-top design allows users to quickly and easily move, add or change cables. OnTraccanbeused inplenumspaces and is UL classified for use as an equipment grounding conductor. Constructed of 5mm and 6mm diameter steel wires, and welded in 2'' x 4'' (50mm x 100mm) intersections, OnTrac offers a solid and reliable solution for critical network cables. Optional splices and fasteners allow trays to be connected end-to-end or in an L-, T- or Y-shaped intersection to match pathway requirements, while ceiling, wall, floor and rack system supports permit multiple installation possibilities. Cable tray inserts, covers, dividers, bend radius, radius drops, power brackets, label holders and grounding clamps are also available. Cicoil has developed silicone cables for extreme operating conditions, including low temperatures (-65°C) and severe weather. Designed for use in land, sea and air equipment, these halogen–free and flame resistant (UL 94 V-0) cables offer an alternative to PVC, neoprene and polyurethane cables that are less reliable than silicone in sub–zero temperatures. Arctic cable

A shock absorbing silicone encapsulation needs no external conduit for protection, retains its shape and flexibility and is said to resist wearing or cracking even after long–term exposure to intensely cold environments. The durable silicone is “self–healing” from small punctures, and cable jacket damage can be easily repaired on site.

flat cable, precisely controlling the inner component spacing, jacket thickness and the overall cable shape. Incorporating multiple elements into a single, compact flat cable allows for a tighter bend radius, noise reduction and greater current carrying capacity.

The new “air cut” passive cutting option offers touch–free front–cutting for use on sensitive chip surfaces.

LSZH wire and cable

Northwire has launched a UL/CSA AWM approved LSZH technical wire and cable with low smoke zero halogen for both insulation and jacket. The new product has been designed to provide cold temperature resistance with improved bend, variable, torsional and rolling flexibility across a temperature range of –50°C to 80°C. Custom cable designs are available, over-mold and assembly compatible and can be coiled for retractile cord applications. LSZH has a smaller than standard diameter and will be suitable for closely confined areas, such as rolling stock, aerospace or marine shipboard cable, where protection of people and equipment from toxic and corrosive gas is essential. Kevin DePratter, director of research and development at Northwire, explained the advantage of the company’s new range: “For years, many manufacturers have been touting the attributes of their low smoke halogen-free cable products, but they haven’t told the marketplace that while their jacket is LSZH, the insulation, on the other hand, is olefin-based and does

Bonding at IMAPS

The American subsidiary of Hesse & Knipps Semiconductor Equipment GmbH, Hesse & Knipps Inc, will be demonstrating the new 3mil wire bonding capability on its BJ935 automatic heavy wire bonder for back– end semiconductor packaging at the 45 th International Symposium on Microelec- tronics (IMAPS) in San Diego in September. Hesse & Knipps has enhanced the capabilities of its BJ935 heavy wire bonder to process gold, aluminum and copper semiconductor die bonding wire with diameters from 3mil to 20mil (75 to 500µm). In addition to the new 3mil heavy wire bonding capability, the Bondjet BJ935 offers ribbon bonding from 0.075 x 0.75mm to 0.3 x 2mm on the same platform. The new slim active wire cutter has been adapted for fine pitch to give increased cutter life and yield improvement compared to pas- sive cutting. The cutter enables precise, repeatable positioning and programmable depth of the cutter and better access into dense, complex wire-bonded packages.

Some outdoor cables become stiff and brittle when used in Arctic conditions, but Cicoil’s silicone cables have been developed to be unaffected when exposed to hurricane–force winds, snow and ice storms, sea ice, vibration, salt water submersion, permafrost, high heat (+260 o C), weld spark, physical shock, operational stress, high levels of UV and ozone, de–icing fluids and most chemicals. Cicoil’s extrusion process allows multiple wires, power conductors, shielded pairs, coax conductors, tubing, and design elements such as Cicoil’s StripMount fastening strip to be placed in a single
