Printed circuit board assembly work. Workers examining and assembling printed circuit boards (PCBs). PCBs are circuit boards where the circuitry is printed and etched using templates and chemical techniques. This allows uniform production and high density of circuitry compared to manual techniques. Components, such as capacitors, resistors and microchips, are then added to the circuit board to make the final electronic product. These workers are employed by the Izhevsky Radiozavod company, which specialises in radios. Photographed in 2007 in Moscow, Russia.
