Dykes will continue to advise Flextronics through March.
"I cannot begin to tell you how important Bob has been to the development of Flextronics as a leading company in the EMS industry, both as a director and as CFO," said Michael Marks, chief executive. "Bob served as my most trusted advisor during the rapid development of the company over the past seven years."
Smach has been Flextronics senior vice president of finance since its acquisition of the Dii Group in April 2000.
