4.3 PEC Recognition
The PEC recognition camera detects the ducial marks on the PCB and the
positional deviations are calculated to correct the position of the components to be
placed.

4.4 Component Supply
The tape feeder on the feeder base is shifted to the position where the components
must be supplied.
The placement head is also shifted in the X and Y directions by the X/Y beam and
picks up a component. After that, it places the picked component on the PCB.
4.5 Component Picks
The vacuum nozzles on the placement head are used to pick up the components.
