Design engineers faced with time-to-market issues and faster design cycles have a new online resource -- www.screamingcircuits.com, an Internet-based quick-turn and short-run printed circuit board (PCB) assembly company. The site’s “Get a Quote” feature is available 24 hours a day and lets customers get a PCB assembly quote within 30 seconds. The company says using the online quote and order feature lets designers spend more time working on the design and less time waiting on prototypes. A new service is the assembly of lead-free and RoHS-compliant circuit boards. Canby, Ore.-based Screaming Circuits also helps customers transition to lead-free and RoHS boards and gives a 10 percent first order discount.    . . .       Semtech Corp. of Camarillo, Calif., a supplier of analog and mixed-signal semiconductors used in computer, industrial and communication applications, announced the hiring of 20-year semiconductor and electronics industries veteran Mohan Maheswaran as its president and CEO, effective April 3.
