A system for determining a degree of contamination of production units of a production line for the printing, equipping and reflow soldering of printed circuit boards, and evaluation unit.

System for determining contamination coefficients and/or degrees of contamination in particular during the reflow soldering of printed circuit boards, and associated evaluation unit

The invention concerns a reflow soldering machine for continuously soldering of soldering goods in a process channel along a process direction, whereby the process channel comprises at least one pre-heating zone, at least one soldering zone, and at least one cooling zone, whereby the soldering zone comprises a pressure chamber comprising one base part and one cover part opposite the base part and that can be raised when the reflow soldering machine is operating, wherein the process channel can be covered by at least one covering hood that can be opened, and wherein the cover part is motion-coupled to the covering hood in such a way that when the covering hood is opened, the cover part is also taken along by the covering hood.

Reflow soldering machine for continuously soldering of soldering goods

Soldering apparatus, in particular a reflow soldering apparatus, for the continuous soldering of printed circuit boards along a transport direction, with an entry and an exit for feeding and removing the printed circuit boards, with a process channel including a preheating zone, a soldering zone and/or a cooling zone, and including a main body and at least one cover hood movable between a closed position and an open position, the cover hood enclosing a hood compartment above the process channel in which fan motors are provided. A central suction channel is provided in the hood compartment, in that the first suction elements connected to the suction channel in the hood compartment are provided for the suction of hood compartment air from the hood compartment, in that second suction elements connected to the suction channel in the hood compartment are provided for the suction of process gas from the process channel, and in that a switching device is provided and is configured to switch between an operating mode in which hood compartment air is suctioned via the first suction elements and a cooling mode in which process gas is suctioned via the second suction elements.

Soldering apparatus

A soldering apparatus, in particular a reflow soldering apparatus, for the continuous soldering of printed circuit boards along a transport direction, including a process channel that has a preheating zone, a soldering zone and a cooling zone, and further includes a base body and a cover hood movable between a closed position and an open position, wherein nozzle plates, fan units with fan motors, air ducts that conduct the process gas, filter elements and/or cooling elements are provided in the base body. The soldering apparatus further includes a drawer, which extends along a pull-out direction running transversely to the transport direction, is provided in the base body, with a bottom, a front wall and a rear side. Air ducts for conducting the process gas, at least one replaceable filter element in a filter region and at least one cooling device are provided in the drawer.

A soldering apparatus, in particular a reflow soldering apparatus, for continuous soldering of printed circuit boards along a transport direction, having a process channel that includes a preheating zone, a soldering zone and a cooling zone, having a base body and a cover hood movable between a closed position and an open position, wherein nozzle plates, fan units with fan motors, air channels carrying the process gas, filter elements and/or cooling elements are provided in the base body. At least one fan unit is arranged in or on the base body laterally next to the process channel in the transport direction, and air channels are arranged and provided in such a manner that process gas is blown into the process channel during operation of the at least one fan unit, with the process gas directed through a filter element provided in a filter region after passing through the process channel, and the filtered process gas drawn in by the at least one fan unit.
