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 light weight 16-, 12-, 8- and 3-
nozzle heads. Remove all support pins before performing calibration.
