ABSTRACT:
Volatile organic components are controlled in electronic component assembly processes to prevent deposits on finished circuit boards and the like. The method of controlling the components in a machine having a plurality of enclosed heating zones followed by at least one cooling zone containing gas, and a conveyor for passing circuit boards therethrough on a conveyor path, comprises the steps of removing a portion of gas from at least one of the heating zones, cooling and filtering the portion of gas remote from the heating zones and the cooling zone to condense at least some of the volatile components in the portion of gas, and returning the cooled and filtered portion of gas to at least one other zone of the heating zones and the cooling zone.
