Tectonic Products Ltd has endured the very kinds of earthquake caused by continental drift that its name implies, but the Wokingham, Berkshire company has to be counted a survivor: it has been into receivership twice in the past five years, the last time being bought from the receiver by former Burtons chief Cyril Spencer in 1986; the company now boasts new management, new investment of over UKP2m, and is raring to go with a full line of multilayer, plated through and standard circuit boards, plus VME, Varibus and STE backplanes, and a full board design and assembly service – and gestating marketing agreements in the US and Japan.
