Description

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.
