Electronics companies are similar to pharmaceutical companies, or more specifically "secondary pharmaceutical" (they process to the final product, ie pills etc). I've experience in the latter.
The infrastructure is surprisingly similar. "Clean Rooms", tight temperature control, HVAC, good power supply redundancy, environmental protection, fire control systems, packaging systems to name but a few. Oh, and bright motivated people working in the environment.
Very often companies with those requirements will be attracted to "science park" type environments where some of the workforce requirements are met, supplier and support companies are within an accepted downtime, and the power redundancy is adequate. Oh, and very importantly, that there is almost a guaranteed planning consent by the council.
There are many companies, however, both now and historically that buck this trend and do (or did) very well indeed. If for example, you go to an area that have a very skilled workforce in an industry which has since gone by the wayside with good infrastructure (such as the steel or coal industries for example), or simply pick a great area of talent. A great example of this is Sony in Bridgend (Pencoed), and historically Cadburys in Bournville.
