Welcome to SCL, the UKs most comprehensive manufacturer of Flex, Flex-Rigid, Rigid and RF PCBs

Thank you for visiting our website. Please contact me or my team if you would like to visit our facility. Les Browne Director of Sales: Sales Team:

Established in 1972 Stevenage Circuits Ltd (SCL) has grown to employ around 100 people (annual turnover circa £8 million) and a client base that covers 40 countries. Formally the Stevenage Circuits group comprised of two facilities, the other being Tru-lon a manufacturer of RF and Microwave / Antenna products. In 2010 as part of a major and innovative re-structuring plan, the Royston facilitiy was incorporated into the Stevenage site creating one of the largest, best equipped and most technologicaly advanced PCB manufacturers in Europe (over 43,000 m2 incorporating ISO 7, Class 10,000 clean rooms).

SCL is engineering and technology driven, uniquely we are a 'dedicated' manufacturer of  'three' different PCB technologies Flex (and Flex-Rigid), Rigid and RF (Microwave/Antenna) PCBs (Dedicated means full in-house volume production and test). As such our process handling capability is wide-ranging from 25 um thin up to 13 mm thick core materials. Also as a 'dedicated' manufacturer of all three technologies, SCL hold the largest material and substrate portfolio of any single PCB facility in Europe, this includes ‘specials’ such as antenna foams, ceramic loaded substrates and crystal polymers, in excess of £1.2M stock of RF materials and clad laminates. 

SCL consult, engineer and manufacture from single-sided to complex, leading-edge printed circuit boards that are fully qualified by way of micro section, optical and electrical test to ensure conformance to CECC release or IPC specification (85% of our boards are released to IPC class 3). As an example of our high standard, at SCL all manufacture (including prototyping) is undertaken to produce productionised product, which is robust and repeatable in volume. Note: it is not standard practice among PCB manufacturers to qualify prototype manufacture to this elevated standard; the majority only ensure connectivity.

SCL is also export  license compliant and  we an hold OGEL for military PCB export. SCL will also apply for SIEL and OIEL if required (existing clients and global corporates only).

SCL production capability is small batch to high volume on standard or rapid delivery.
