IRVINE, CA -- After about 50 years in business, PCB fabricator Cosmotronic is planning to close next month.

The Southern California board shop will shut down by the end of February, the firm told PCD&F today.

According to its website, Cosmotronic was founded by Said Cohen in Santa Ana, CA, in the late 1960s, specializing in serving the military and defense industries. It began producing rigid-flex and metal-core boards in the 1980s.

In 1975, it moved to a 15,000 sq. ft. facility in Irvine. It doubled in size with a second building in 1990, employing nearly 100 workers.

In 2001, Cohen sold Cosmotronic to Thayer Capital, which in turn sold it to JR Controls in 2006. Through acquisitions, JR Controls also purchased Winonics in Brea, CA, and Bench 2 Bench Technologies in Fullerton, CA. The latter two plants will remain open, a Cosmotronic employee told PCD&F.
