Offer on Select DEN-ON SMD Rework Stations
Torrance, CA — Seika Machinery, Inc. is providing a limited time spe- cial on select DEN-ON Instruments
500SIII SMD Rework station series valid until the end of August 2015. The RD-500III model is de-
signed for large board sizes up to 500 x 600mm (19.7 x 23.6-in.) while the more compact RD- 500SIII model can work with board sizes up to 400 x 420mm (15.7 x 16.5-in.). Both models are versatile and can work with both leaded and lead- free solder al- loys. These models also offer a special design that utilizes both hot gas and IR heating for a wide array of applications. As DEN-ON Instruments’
distributor for North America, Seika Machinery represents that company’s complete line of sol- dering, desoldering, rework sys-
tems and tools. Contact: Seika Machinery,

Shielding Compounds
Pawcatuck, CT — Lehvoss North America, a subsidiary of Lehmann & Voss & Co., has introduced LUVO- COM® ES, a new generation of ther- moplastic shielding compounds with outstanding performance against electromagnetic waves and at small- er wall thicknesses. These new com- pounds are engineered for the hous- ings of electric and electronic devices such as computers, radios, phones, and laboratory equipment. As devices become smaller and
smaller, and electromagnetic pollu- tion becomes more serious with the increased use of electrical and elec- tronic devices, the need for improved shielding materials is escalating,? ex- plained Robert Healy, Business De-
compared to competitive compound products, LUVOCOM ES reportedly offers better shielding performance. According to the company, typical shielding materials available thus far have been less than effective, causing customers to design with thicker walls or use additional metal coatings or steel sheets to protect against the electromagnetic waves. This means extra work for installation and extra costs.
LUVOCOM ES eliminates the
need for secondary operations/instal- lation of metal sheets or films or coatings, thus offering the potential for reduced system costs. Further- more parts can be smaller (no in- lays/space for inlays) and more envi- ronmentally friendly due to less material mix and weight savings. The compounds are ready
LUVOCOM ES ensures effective
shielding of electromagnetic waves in laboratory instruments.
velopment Manager at Lehvoss North America. Because polymers are non-conductors, they are perme- able to electromagnetic waves of up to approximately 100GHz. Shielding is necessary to prevent electromagnetic environmental pollution and hence an influence on sensitive electronic devices. A shielding effect is achieved by
making the housings of the electronic components electrically conducting. This is done through the use of metal sheets and films, conductive coatings, and conductive compounds. When
to use (no adding of master- batches before or at the hopper of the injection molding ma- chine) and their rheology is op- timized for easy processing and thin walls. This results in a much lower risk of defects in molded parts due to imperfectly distributed fillers when com- pared to polymers and master- batches that have been dry blended at the injection mold- ing machine. Due to its inherently high
electrical conductivity, LUVOCOM ES allows small contact areas for necessary electric grounding. The in- novative filler system enables an at- tractive surface appearance. Overall shrinkage, flow and mechanical properties for some of the compounds are close to standard PC/ABS with 20 percent glass fibers. Flame retar-
dant materials are also available. Contact: Lehvoss North America
