6.3.3 PCB position recognition and temperature compensation
The PCB recognition is necessary to determined the correct position of the PCB in the machine
(Transport --> Placement area).
It should be two fiducials on each PCB minimum. With this two fiducial we are able to determined
the X/Y position and the angle of the PCB in the transport. The fiducials shouldn‘t be in one line
on the PCB.
Up to 3 fiducials can program for the PCB recognition. With the third fiducial, we determined ad-
ditional to the position of the PCB the geometric data of the PCB layout, that means is the PCB
stretch.
The Siplace X machine increase the accuracy, so that we make additional to the PCB recognition
a temperature compensation with the second gantry in the placement area.
