Contract manufacturer Flextronics International (FLEX.O) expects to post double-digit revenue growth for the rest of the year, helped by a doubling in PC sales, its chief executive said today.

Revenue from its recently revamped PC manufacturing unit is expected to double to US$2 billion ($2.7 billion) this year, and will reach US$4 billion by the end of 2011, Flextronics Chief Executive Mike McNamara told Reuters in an interview in the southern Chinese city of Shenzhen.

“We think those numbers are going to come through and the PC industry is not growing 100% a year, so that’s three years of 100% growth,” McNamara said.

Flextronics, which counts global tech brands such as Hewlett-Packard (HPQ.N) as its clients, said in June that revenue in its fiscal second quarter was likely to clock in at US$6.8 billion to US$7.2 billion.

The Singapore-based contract manufacturer had beat earnings expectations in the first quarter and was bullish on solid demand in technology sectors such as semiconductors.
