Position Check of PCBs Before Assembly Process by Vision System

Before PCBs are loaded in SMD systems, they must be placed in the correct position and fed into the system. For the position test, a vision system is installed above the PCBs, which records a crosshair printed on the circuit board as a reference point. From this, the so-called “offset” is determined and transferred to the machine control. In the subsequent assembly process, all components are applied in the correct position – thereby minimizing misplacement. The PCB is also uniquely identified by the vision system via decoding of a DataMatrix code.

Vision Systems

Vision systems solve complex image processing applications. They consist of up to 16 machine vision cameras with C mount lenses, external illumination and a machine vision controller. The suitable software offers numerous evaluation options and a wide range of interfaces make connectivity easier.
