A method and a device for placing a multitude of shaped parts of solder material ( ) on a bond pad arrangement ( ) of a substrate ( ), said bond pad arrangement comprising a multitude of bond pads ( ), and for subsequent re-melting of the shaped parts of solder material on the bond pads ( ), with arrangement of a template device ( ) comprising a multitude of template apertures ( ) for accommodating shaped parts of solder material ( ) opposite a substrate ( ) comprising a bond pad arrangement ( ), such that the shaped parts of solder material are associated with the individual bond pads ( ); and application of laser energy to the shaped parts of solder material ( ) accommodated in the template apertures ( ) using a laser device ( ) arranged at the rear of the template device ( ) such that said laser energy is applied to the shaped parts of solder material through the template device.

Method and device for placing and remelting shaped pieces consisting of solder material

A method for the thermal connection of overlapping connecting surfaces ( ) of two substrates ( ), at least one substrate ( ) being 5 transparent and laser energy being applied to the connecting surfaces ( ) from a rear side ( ) of the transparent substrate ( ), laser energy being applied separately to each of the contact pairs ( ) constructed between two connecting surfaces ( ) of the opposing substrates ( ).
