CONNECTION, METHOD AND DEVICE FOR THE UNIFORM COUPLING-IN OF LASER BEAMS DURING LASER WELDING AND LASER SOLDERING, IN PARTICULAR ON HIGHLY REFLECTIVE MATERIALS

摘要

According to the present invention, when a fixedly positioned laser beam (11) is used for connecting, in particular laser welding or laser soldering, mechanical and/or electrical contacts (1), in particular of an electronic component, to respective contact partners (3), in particular arranged on a substrate (2), the same mechanical welding parameters are to be constantly provided for the laser beam (11) at each position of a movement of the desired laser location from a setting-down position (A) to an end position (C) of the connection (1) with respect to the contact partner (3) that is brought about by pressing of the connection (1) perpendicularly in the direction of the contact partner (3). In particular in the case of connections (1) with highly reflective materials, this achieves the object that the connection (1) is shaped in such a way that the connection (1) is created over a longitudinal extent or over a two-dimensional area along the surface (13) of an ellipse and convexly with respect to the contact partner (3).
