Printed circuit component placement method
Abstract:
A component placement machine includes: a transport device for transporting PCBs in an X-direction; first and a second feeder areas; at least one Y-slide beam that is drivable in the X-direction; and at least two placement heads on each Y-slide beam, which placement heads are independently drivable in the Y-direction and dependently drivable in the X-direction. Each feeder area includes at least one feeder for storing components. Such a machine enables a number of actions to be performed simultaneously. For example, within a certain period of time, a plurality of placement heads can simultaneously pick up components from a feeder, while other placement heads, which previously picked up components, may be moved to desired X-Y positions of the PCB which the previously picked up components may be placed, thereby resulting in an improved output.
