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.
