Dow Corning Corp. (Midland, MI), a provider of silicon-based technology, has launched a partnering approach specifically designed to help electronics industry customers solve business problems and seize emerging opportunities. The Electronic Solutions initiative expands the company's value proposition beyond materials and signals a significant shift in the company's business strategy.
Drawing on its 60 years as a materials manufacturer and the capabilities of its partners throughout the electronics industry, Dow Corning can now help customers meet many business challenges, including product and application development; materials, process and equipment integration; facilities design and engineering; and supply chain management (including environmental, health and safety capabilities).
The company has also tapped Arthur Hanlon to lead the solutions strategy. In this role, Hanlon oversees the development of customer-centered solutions across Dow Corning's semiconductor, packaging, systems assembly and subsystems assembly market segments, including emerging business programs.
To date, Dow Corning has helped many companies throughout the electronics industry overcome specific business challenges, including factory and geographic expansions, supply chain optimization, equipment procurement and product research and development.
"Where we once had limited points of contact with customers, typically between our sales person and the company's procurement department, we now interface with companies on multiple levels," said Tom Cook, executive director. "Our engineers work with customers' engineers to troubleshoot process problems on their manufacturing lines, our scientists support customers' scientists in creating new formulations, R&D teams help customers' brand managers create new markets and our business development leaders work with our customer's business owners to outline and develop proposals to meet their significant business challenges."

Printing printed circuit boards (PCBs) in highly flexible production environment demands new solutions for efficient use of a screen/stencil printer. Standard inline printers are not ideally suited since various production lines or production cells would need a machine for each section.
The SP500 batch printer from ESSEMTEC (Glassboro, NJ) can be used for printing several lines or cells, as it provides a fully automatic process.
All printing parameters are stored in an internal database and users can also store information such as set up info and solder paste and stencil specifications. The operator can easily select the product and gets all necessary information for setting the new batch.
The printer automatically aligns the PCBs to the stencils with an integrated vision system. The printer can be operated in a manual loading or fully automatic batch-loading mode. The related PCB loading/unloading system automatically feeds PCBs from a rack, prints them and stores them on the same rack. The integrated underside stencil cleaning system makes sure that the batch is properly printed, avoiding blocked stencil apertures. Different cycles can be programmed and three different cleaning modes—dry, wet or vacuum—can be selected and combined.
The complete printing cycle is fully automatic; a full rack of PCBs can be printed and then inserted to a surface-mount device assembly line or cell. Problems with paste drying on the stencil are avoided.

EMC has introduced the Cyberclean Series 6000, Model 7883CD batch washer. The stainless steel cleaner washes and dries in one chamber. Features include wash and dry temperatures to 93ºC; a built-in adjustable water softener, detergent and neutralizer dispensing system; and a HEPA filtration system with adjustable drying.
Other important features include a 106-gallon per minute circulation pump, thermally protected for overheating, and eight standard wash recipe times with holding times and temperatures that are fully adjustable. The washer also includes an RS-232 printer port for monitoring and validation.
The dual rotary spray arms are located at the top and bottom of the cleaning chamber for efficient cleaning within the chamber. The unit can be configured in 208/220V three phase, 20 Amps or 208/220V single phase 30 Amps. Running sound decibels are rated at 54.0 dB @ 1 meter.
The batch cleaner has a footprint of 33.5 x 35.5 x 27.5 in. Interior wash chamber is 18.5 x 20.5 x 20.5 in.
