Abstract: A soldering apparatus includes an application device, a conveying device and an application nozzle. The application device has a laser duct extending straight from a laser entry at the top to a laser exit at the bottom and a drop duct that extends from a drop entry at the top to a drop exit at the bottom of the application device. The conveying device separately conveys solder bodies to the drop entry. The application nozzle temporarily holds solder bodies received from the drop exit. The laser and drop ducts are interconnected over their entire lengths from the top to the bottom of the application device. The drop entry and laser entry are side by side and form a common entry. The drop exit and laser exit are spatially coincident and form a common exit that is smaller than the common entry. The application nozzle is connected to the common exit.
