Method of mounting electronic component and electronic component mounting apparatus

摘要

In an electronic component mounting apparatus, when a replacement work of a component feeding unit (13) is performed on a component feeding device on one side, the operating ratio of a beam (7,8) on the one side is increased to enhance the production efficiency. While a component feeding unit (13) of a first component feeding device (3) on a front side is being replaced, a beam (7) on the front side moves onto a second component feeding device (5) on a rear side, a first mounting head (11) moves between a printed board (P) on a carrying device and the second component feeding device (5) in the similar manner to a second mounting head (10), and suction nozzles (101/111) mounted on each of the first and second mounting heads (10,11) pick up electronic components from the second component feeding device (5) and mounts the electronic components on the printed board (P).
