Compiling the placement position (X/Y coordinates and angle) 3
following values are taken in account for calculating the theoretical placement position:
3.2.2 Communication on HF placement machine
The placement data files, stored at the hard drive, are compiled at the station computer. This com-
piling add the calibrated values, taken during calibration in Sitest, to the pick up and placement
data.

3.2.3 Machine Controller Communication
For the calculation of the ’pick up coordinates’ the MC add the pick up correction values (former
pick up offsets) to the pick up coordinates.
For the calculation of the
’placement coordinates’ the MC add the PCB position correction values
and the component correction values (from camera evaluation) to the placement coordinates.

3.3 CAN Bus
3.3.1 History of CAN
The development of CAN began when more and more electronic devices were implemented into
modern motor vehicles. Examples of such devices include engine management systems, active
suspension, ABS, gear control, lighting control, air conditioning, airbags and central locking. All
this means more safety and more comfort for the driver and of course a reduction of fuel consump-
tion and exhaust emissions.
