inTEST Corp., an independent designer, manufacturer and marketer of semiconductor automatic test equipment (ATE) interface solutions and temperature management products, recently announced its acquisition of privately-held Sigma Systems Corp.

Sigma Systems, founded in 1956, is located in El Cajon, CA, and is a leading manufacturer of thermal platforms, custom configured environmental chambers and other environmental test solutions for a variety of industries including automotive, medical/pharmaceutical, electronic, aerospace/defense and semiconductor.

Robert E. Matthiessen, inTEST’s president and chief executive officer, commented, “inTEST Corp. has been involved primarily in the semiconductor business from its inception. The once-robust growth in the semiconductor capital equipment industry has slowed considerably in recent years. Consequently we embarked on a strategy of pursuing business opportunities outside of the semiconductor industry and our vehicle for this endeavor has been our Temptronic Corp. subsidiary. Presently, approximately 10 to 15 percent of inTEST’s net revenues come from non-semiconductor customers. Sigma Systems will be joining our Temperature Management product segment in a strategic fit with Temptronic that will greatly expand our product offerings outside the semiconductor market. Sigma System’s products are highly complementary to our other Temperature Management products and will greatly facilitate inTEST’s further penetration into non-semiconductor markets.”
