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

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.

Soldering apparatus

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.
