Our Story

Established in 1988. The origins of Prima Electronic Services Ltd, and its electronics manufacturing services (EMS) operations, are tied into the life’s work of Tony Hall, its founder and long-time managing director. Prima’s steady growth is strongly linked to the growing technology cluster around Cambridge as well as its sought-after expertise in electronics manufacturing that proved instrumental in supporting local startups’ growth.

In the first few years, the company comprised just half a dozen employees, but it steadily grew over the decades that followed. The projects in which Prima was involved were varied, but ones concerning audio-visual, telecommunications, instrumentation, and printing technology were the most common.Prima continued to invest and develop with the deployment of state-of-the art manufacturing and testing equipment as well as the recruitment of top-quality engineering talent.

1988 – 2000 Beginnings

2001 - 2017 Development and steady growth

A new chapter

In 2018, Prima was acquired and became part of the Russel Industries. As a new decade begins Prima is looking to transform and accelerate its growth by executing a comprehensive strategy that involves expanding its range of services, entering new geographies and industries as well as carrying out significant modernization programs including digitization, automation, and manufacturing optimisation.

Additionally, through newly established links to several offshore manufacturing affiliates, the company is now able to support its customers from prototyping all the way through to very high-volume production. Prima is committed to maintaining its high level of service to its loyal customer base as well as to continue serving and supporting the growth of the local Cambridgeshire technology start-up businesses as it did for the past few decades.
