Abstract:
1. A wave solder machine configured to perform a wave solder operation on an electronic substrate, the wave solder machine comprising: a fluxing station configured to apply flux onto the electronic substrate; a pre-heating station configured to heat the electronic substrate; a wave soldering station configured to attach electronic components to the electronic substrate with solder; a conveyor configured to transport substrates through a tunnel passing through the fluxing station, the pre-heating station and the wave soldering station; and a flux management system configured to remove contaminants from the tunnel, the flux management system being in fluid communication with the tunnel for passage of a vapor stream from the tunnel through the flux management system and back to the tunnel, the flux management system including a housing, a first stage unit provided within the housing, and a second stage unit provided within the housing and in fluid communication with the first stage unit, the first stage unit including an air-to-air heat exchanger using compressed air as a cooling medium to condense flux vapor on contact with the air-to-air heat exchanger, the first stage unit separating larger particles from a gas stream, the air-to-air heat exchanger including a plurality of tubes configured to receive compressed air, the air-to-air heat exchanger including at least one airflow deflector plate in thermal contact with the plurality of tubes of the air-to-air heat exchanger.
