The laser assembly is mounted above the transport system on a linear driven X/Y axis. The PCB to be marked is taken over on the transport system, fixed in position with an integrated side clamp and moved into the target area for lasering. The laser now moves to a pre-programmed position and marks the predefined content, such as barcode, datamatrix codes, text or logos onto the product. The code content is verified with a high-resolution camera-system. The fiducial recognition can be used for position correction as standard.
