7.3.2 Placement principle Twin-head
During PCB-transport time wait the gantry at theoretical fiducial position to execute PCB-position
recognition (and bad mark recognition) after clamping. With " Whispering down the machine"
gantry 3 (at PA2) center only 2 fiducials of PCB recognition.
Than the TWIN-head start to collect one component with module 1 and one component with mod-
ule 2. Than follows a centering sequence for this two components.
7.3.3 Prepare pick up process module 1
Please Note:
For more accuracy the first five components centered above the IC camera in 0° and 180° at each
PCB board (SW 504). With the SW 505 we will check the offset between nozzle and IC/ FC cam-
era via a fiducial near the IC/FC camera after a defined time of 3 min.
