Abstract: A pyrometer is located beneath a soldering path downstream of a flow nozzle and is shielded by a metal plate which extends transversely relative to the soldering direction and obliquely upwardly toward the path. The pyrometer is connected to a limit value generator which responds when the limit value is exceeded.

Abstract: A production facility is provided for automatic assembly and testing of electronic card modules. Heretofore it has only been possible to manufacture card modules in batches without a quick conversion to another type of production, as required, being economically possible. This disadvantage is avoided by the present invention in that all required operating elements (component parts, tools, automatic assembly and testing units) are controlled in direct access with set-up time approaching zero for the production line via an extensive computer hierarchy in which the assembly and test line are available. A master computer administers the cell computers assigned to the individual processing stations which, in turn, control the machine computers. The conveying system has its own control available.
