    Silicon Valley Pioneers

    Industrial Electric Mfg (IEM) began in a barn on a family ranch in Fremont, California. We grew along with Silicon Valley, expanding to a 12,000 sq. ft. facility in 1957, 70,000 sq. ft. in 1980, 105,000 sq. ft. in 2003, and 135,000 sq. ft. by 2013. Today, IEM has 1.5M+ sq.ft. of manufacturing capacity.
