Rectron Limited was established in January 1976 in Tu-Cheng, Taipei by a team of experienced semiconductor engineers. Financed locally, Rectron very quickly emerged as a recognized supplier of quality discrete semi-conductors.  In 1981, Rectron increased sales revenues with direct access to the global semiconductor market via a network of exclusive Distributors and Agents.

Rectron received approval for initial Public Offering of common stock in January 1985 and has opened wholly owned subsidiaries in Los Angeles, USA; London, England; and Hong Kong.  Further expansion came in early 1994 when Rectron commissioned a plant in China to enhance our competitive advantage and increase discrete product manufacturing capacity.
