A soldering installation (1) is provided for run-through and shuttle operation, in particular for the run-through soldering of printed circuit boards on a soldering machine. It is equipped with a feeder mechanism (4) for the transport of soldering frames (18) to which printed circuit boards are fixed. The feeder mechanism (4) has a travel distance of at least 2 frames. In the first half of the feeder mechanism (4) is a device (31) for the holding of a frame (18) as well as an activator (32) for the release of the frame (18). A transport mechanism, (5) running synchronously with the feeder mechanism (4) bridges the soldering machine. An electric motor (37) with adjustable speed and reversibility drives these parts (4 and 5). A program control sttion (54) with memory register (72) and sensors (67) controls the switching on and off of parts of the installation in such a way that with run-through operating the frame holding station (31) secures the maintenance of a minimum distance from frame to frame on the frame transport mechanisms and also activates and terminates the operation of the fluxer (25), the dryer/preheater (26, 27) and the soldering station (28) during the passage of a frame. This soldering installation is sensibly equipped to handle small as well as large numbers of printed circuit boards to be soldered, because it is equipped for shuttle operation as well as, in the case of peak loads, run-through, unidirectional operation, and is also capable of being integrated into a production line.
