Radio Robot Squirts Out 3 a Minute

A COMPLETE radio set every 20 seconds is the production goal of this new British automatic machine known as ECME (Electronic Circuit Making Equipment). Nearing completion at the research laboratories of Sargrove Electronics, Ltd., this automaton uses the sprayed-circuit technique to do the jobs of a double line of skilled workers. Wiring mistakes are eliminated, and the machine even makes its own tests, signaling the location of any defects in the circuit.

Plastic plates are fed into each end of the two parallel rows of electronic units shown in the photograph at the top of p. 160. As the plates move down the line, all the necessary inductances, capacitors, resistors, and potentiometer tracks are “built up.” After lacquering, other units automatically insert rivets, eyelets, and studs. When two plates are joined together at the end of the line, they form a complete radio receiver except for a few parts such as electrolytic condensers, tubes, and loudspeaker, which are added by hand. It is claimed that the sets will be both lighter and sturdier than those made with wired circuits.
