The surface height of several points on the PCB top surface is measured by the height sensor, and
according to the result, PCB warpage condition is predicted and the nozzle lowering position is controlled
for placement operation. This operation procedure is also shared by the 8- and 3-nozzle heads.
●Remove all support pins before performing calibration.
●If the height sensor jig cannot be set up, manually load a PCB from the pre-process machine and set it
up using a workbench (please prepare yourself.)

Measurement
part
●Confirm that there is no contamination
or stain on the measurement part.
●For calibration of the height sensor,
jigs on both the front and rear heads
are set to lane 1.
●Push the jig to the fixed side on the
rail, and set the jig as the right edge of
the jig matches to the mark on the
conveyor. (The picture on the right
shows for flowing from left to right)
●For flowing from right to left, the left
edge of the jig shall be matched to the
mark on the conveyor.
