Sales of Cookson EAM’s high reliability Alpha Vaculoy SACX now account for 46% of its lead-free bar sales in Europe. “Since its introduction in early 2004, sales of SACX have grown steadily, and over the last six months we have experienced growth as our customers are looking for the high performance, reliability and value they find only in SACX," said Gerry Campbell, global product manager. "The recent increases in the prices of tin and silver have forced our customers to look at lower cost alternatives to reduce the cost burden of moving to Pb-free processes. SACX costs 30% less per kg…without compromising process yield or reliability." Its fast wetting speed and improved solderability reportedly outperforms all Sn/Cu-based alloys. Is said to provide excellent drainage and minimize bridging defects. Creates strong, mechanically sound joints with long-term reliability. Minimizes dross generation, resulting in low process maintenance and reduced product waste. Its process window supports the use of a range of flux technologies.
No. 926 is an electrically-heated, 250°F shelf oven from Grieve, currently used for aging electrical components. 12kW installed in Nichrome wire elements provide heat to the load. Workspace measures 68 x 30 x 66”. A 1000 CFM, 1 HP recirculating blower provides horizontal airflow.
Shelf oven features 4” insulated walls, aluminized steel interior and exterior, plus a 20 x 56” double-pane Lexan window in each of the unit’s two doors.
Includes a disposable fresh air filter, digital indicating temperature controller, manual reset excess temperature controller with separate contactors, recirculating blow airflow safety switch and a remote control panel.
SSM4A rework machine is suitable for power semiconductors, bobbins, sensors, transformers and other components. Is ergonomically designed, fast and productive, even for semi-skilled operators. Retrofits for existing SSM 4-, SSM 9- and PCBRM machines are available. Can be equipped with a nitrogen option.
Tyco Electronics has a new high-current Card Edge connector based on its SEC-II product line. The power connectors are said to increase the current carrying capacity by over 70% compared to traditional card edge connectors. The increased ampacity comes from a triple beam power contact, which increases the cross sectional area of the contact yet maintains the same mating force and contact wipe as the SEC-II signal contacts.
Carries up to 25 Amps per contact and is available in a variety of combinations of power and signal contacts combined in a single molded housing.
Available with three mounting options: *PCB tails for soldering to plated through-holes *Compliant press-fit PCB tails
*Straddle/surface-mount PCB tails for co-planar applications
Are suited for traditional Voltage Regulator Module (VRM) applications.
Max-Kleen Heavy-Duty Degreasers are industrial degreasers formulated to tackle demanding cleaning jobs. The degreasers provide fast, easy removal of grease, tar, asphalt, oil and grime in industrial degreasing operations, including manufacture and maintenance of armatures, compressors, electrical motors and equipment, bearings, gear drives, brakes, springs and flywheels. Xtreme degreaser is the most aggressive cleaner in the line. It is non-flammable, non-corrosive and non-conductive. It evaporates quickly, leaving behind no residue. Lectro-Solv degreaser is best for electrical degreasing applications. Is non-flammable, non-corrosive and non-conductive. It has a dielectric breakdown of 30,000 volts. Citrus degreaser dissolves oxidized grease, oil, wax tar and sludge. Contains no chlorinated solvents, and has a flash point above 100o F. Has an orange odor.
Kester will provide lead-free resources, technologies and products during Nepcon China this week.
The company will feature numerous products from its Lead-Free Solutions (products and services) portfolio to help companies beat the July 1, 2006 RoHS Directive deadline. Featured products are EnviroMark 907 lead-free no-clean paste and its low-cost Ultrapure K100 lead-free bar solder alloy, along with technical services to help manufacturers assemble lead-free.
EM907 reportedly exceeds customers’ expectations for high-yield Pb-free manufacturing, and was designed for the higher thermal demands of assembling with higher melting temperature Pb-free alloys. Featuring a long stencil life, the solder paste is said to offer Pb-free joints that closely resemble those achieved with Sn/Pb solder paste.
K100 is a near-eutectic tin/copper alloy with controlled metallic dopants to control the grain structure within the solder joint. This improves joint reliability and virtually eliminates common defects such as icicling and bridging. The improved grain structure also results in completely filled and shinier solder joints than traditional lead-free alloy alternatives.
