Sixty years ago John A. McDonald of Glendale, CA developed a multiple-purpose continuity and voltage tester for
electrical circuits. A patent was applied for in 1952 and granted in 1956. He and a partner formed the Delta
Electrical Specialty Company (DESCO) to manufacture and sell the device named the Circuitracer. That first
Desco item is still manufactured today.
In 1979 John McDonald sold his company to John Brake and Wayne Hunter. John and Wayne incorporated under
the name Desco Industries, Inc. (DII) in Brea, CA. The business quickly outgrew the Brea facility and was moved
to Walnut, CA in 1981. Desco was moved again in 1999 to a much larger building in Chino, CA. Corporate
headquarters is also located here. After 33 years as DII we have sales and manufacturing facilities in ten locations
worldwide: seven in the United States, two in the United Kingdom and one in Japan. We employ nearly 200 people
and have grown through the development of new products and the acquisition of companies with well established
reputations for quality.
Our primary focus is on the control of electrostatic discharge damage in micro circuits and we manufacture a large
variety of products involved in the manufacture, testing and repair of electronic circuits. In addition, we make
specialty tools, personnel identification badges and custom products to customer's specifications.
DII is fully integrated into internet and EDI technology. Over 50% of our orders are processed through our
collective websites and 20% are processed via EDI.
We market our products through seven core brands and 16 web sites.
