ABSTRACT:
A device for a simultaneous soldering of at least two connecting elements (52) of an electronic structural element (54) on a circuit plate bar (50) comprises a workpiece support (44) and a laser (10) for producing the soldering energy, and has arranged two soldering beams (20) of at least approximately equal intensity, having in their path, at any time, an optic (30) for focusing the soldering beams (20) on the soldering spots. The resonator of the laser (10) is closed on both of its londitudinal sides by a semi-reflecting mirror (12) for production of a relative movement between the soldering beams (20) and the workpiece support (44), there is, at any time, a deflecting device provided, having two by a control device (48) independently adjustable mirrors (38, 40) for an operative deflection of the respective soldering beam (20).
