Our History

The Company was formed in 1987 as a Design and Manufacturing Company specialising in Thick Film Hybrids and the packaging of micro-electronic devices.  CIL was originally based in Whitchurch, Hampshire, some 15 miles from the current facilities today in Andover, which it acquired in late 2005. CIL has matured and grown to be one of the leading UK Electronics Manufacturing Companies and has enjoyed steady growth. Its continued policy of investing in plant, equipment and its staff has solidified CIL's reputation for supplying high quality products at competitive commercial costs.

CIL House totalling 24,000sqft, is home to a dedicated RAPID prototype SMT facility as well as five SMT lines for small to medium volume PCBA assemblies. It also houses all associated equipment / processes such as 3D AOI, flying probe test, X-Ray, CT Scan, thru hole soldering and inspection / test.

Customers started to express interests in CIL providing high level product testing and complete Product Build or Box build. We of course listened, and in 2010 we opened our Box Build Facility here in Andover, making a total of 36,000sq ft of Electronics Production across the 2 sites, making CIL's Facility one of the most complete, in terms of its offerings as a one stop solution, the most versatile in the end to end technology we can provide and the most flexible, by way of our ability to flex and react to our Customers demands in the market today. In 2012 we joined the Connexion Technologies Group, and now with the combined offerings of the Connexion's Group are able to provide a much wider manufacturing support services, such as RF & Microwave Components, and systems, the associated design applications support as well as RF Test Equipment Design and Manufacture. 

During the COVID pandemic, CIL remained fully operational as it was both involved in multiple Ventilator Challenge programs, one of which resulted in product being picked up by Her Majesty the Queen's Helicopter and CIL had key worker status throughout.

In late Dec 2021, CIL took the decision to create the UK's largest Semiconductor packaging facility in Andover UK in addition CIL House. After almost 18 months of planning and fitting out, in June 2023 the 64,000sq ft facility of BP2 came on line. Contained within this facility is a single 15,000sq ft ISO 7 (Class 10,000) cleanroom and all of CIL's micro-electronics and power device assembly. CIL now has 100,000sq ft of manufacturing and office space across 3 Andover sites and we currently employ over 205 highly qualified and skilful staff.

Over its 36-year history, CIL has won multiple manufacturing and technological development awards. All of this culminated in 2022 when CIL won the National ELEKTRA award for “Manufacturer of the Year”.

At CIL we plan to succeed and never fail!  Our values dictate that we have an unrivalled passion for providing the best Electronics Manufacturing Support on offer, with an honest and open attitude to business, the whole CIL team is available to assist you in making your business count.
