Description

Components of radio receivers made on the ECME machine. In 1947, John Sargrove developed a machine for producing electronic circuits for radio sets. This took the name 'ECME' - Electronic Circuit Making Equipment. ECME worked by automatically milling the bakelite blanks that formed the circuit boards. It then added resistors, capacitors and the metallic circuits by a spraying proces, leaving only the final asembly to be completed by hand. Though ECME worked succesfully it required high tooling costs and long production runs to make the proces economic. FInance and orders were insufficient and the project ceased within a year.
