SANTA CLARA, CALIF. — Spraylat Corp. is developing in-line technologies to apply conductive polymers for electronic shielding inside portable-device enclosures.
"We started working with [Telefon AB LM] Ericsson and a Swedish inventor about three years ago on the marrying of a Tampo printing or pad-printing type of process," Gary Shawhan, marketing development manager with Spraylat's EMC Solutions Group, said during the Portable Design 2001 conference held Jan. 29-31 in Santa Clara.
"That technology has slowly come to the point where Ericsson has been issued a number of patents associated with the process," Shawhan said.
Molders like the efficiency of in-line solutions, he said. "It will be technology embraced by people doing molding but not anxious to set up off-line paint application or alternate coating technologies."
Spraylat also offers a process called FormShield, where it thermoforms thin-gauge polycarbonate films and uses a proprietary adhesive to attach the conformable shield to a plastic enclosure or printed wiring board.
Mount Vernon, N.Y.-based Spraylat has annual sales of about $100 million and also makes industrial and specialty coatings.
