Our Journey

Celebrating its 60th anniversary in 2017, Dynex has a long and proud history of manufacturing and providing semiconductor products to the world. 

1956

British Thomson-Houston Company Limited

A semiconductor business was opened in Lincoln by AEI Semiconductors in 1956 manufacturing some of the first silicon-based semiconductor components in the world.

1963

AEI Semiconductors

The BTH name was replaced by Associated Electrical Industries Ltd (AEI) on their products.

1980

Marconi Electronic Devices

Marconi Electronic Systems (MES), or GEC-Marconi, was the defence arm of The General Electric Company (GEC). The factory at Doddington Road had 2 divisions, Microwave(including Hybrid) and Integrated circuits with a Lincoln design centre capable of semi-custom design for large scale integration.

1990

GEC Plessey Semiconductors Ltd.

As a result of various mergers and acquisitions in the electrical engineering industry, the business continued to operate under the name of GEC Plessey Semiconductors.

1998

Mitel Semiconductors

Mitel acquires the GEC Plessey Semiconductor Group. The combined semiconductor business ranks Mitel among the top ten networking companies in the world and provides the ability to produce bipolar, Complementary Metal Oxide Semiconductor (CMOS) and optoelectronic components.

2000

Dynex Power Inc.

In 2000, Dynex Power Inc, a small, publicly quoted Canadian company, formed Dynex Semiconductor Ltd to purchase the assets of Mitel Semiconductors.

2000

Dynex Semiconductor Ltd.
