Device for soldering electronic structural elements of a circuit plate bar

A device for soldering simultaneously at least two connecting elements of an electronic structural element on a circuit plate bar comprising a workpiece support, a laser for producing the soldering energy, at least two soldering beams provided with at least approximately equal intensity, in the path of which is arranged at any given time an optic for focusing and aligning the soldering beams on the soldering spots, and means for the production of a relative movement between the soldering beams and a workpiece support, characterized in that the device further comprises a pair of semi-reflecting mirrors (12) for closing both longitudinal ends of a resonator of the laser (10) utilized for producing both soldering beams (20), a control device (48), and the means for production of the relative movement between the soldering beams and the workpiece support comprises a deflecting device (28) having at least two independently adjustable mirrors (38, 40), wherein the control device (48) controls adjustment of the independently adjustable mirrors (38, 40) so as to provide operational deflection of the respective soldering beams (20).
