ABSTRACT:
The automatic soldering of printed circuit boards wherein different boards can be simultaneously processed at different stations, e.g. a fluxing station, a preheating station and a soldering station. An identification station in advance of the fluxing station controls various parameters at the processing stations in response to board type as the boards are indexed through the various stations. Parameters such as location of application, time of application, pump speed etc. may be controlled in response to board type.
