Credit Suisse First Boston expects electronics manufacturing services and component companies to report "mostly inline" second-quarter results.

CSFB said, "Given a slow demand environment, we continue to overweight EMS names that are 'creating their own destiny': leveraging secular margin expansion as Celestica or new business wins as Jabil Circuit and Flextronics International to drive above-average earnings growth."

The cell-phone business and increasing Nortel Networks revenue "should get Flextronics over the line in the second quarter, with the booming Multek PCB business driving an opportunity for margins to beat. Celestica and Sanmina-SCI will both likely achieve earnings consensus on margin improvements from restructuring, despite lackluster revenues," the research firm said.
