摘要： A diffuser plate for a reflow oven includes an upper surface and a plurality of nozzle openings therein. Each of the plurality of nozzle openings has a raised surrounding portion for restricting condensed flux on the upper surface of the diffuser plate from flowing through the nozzles. A drain hole permits condensed flux on the upper surface to flow downward through the plate.

摘要： A reflow oven chamber assembly (50) that is configured to be installed within a reflow oven chamber of a reflow oven includes a chamber housing (52) disposed within the reflow oven chamber, one or more heating elements (66) disposed in the chamber housing, and one or more compression box assemblies (68) disposed in the chamber housing (52). The compression box assembly (68) includes a compression box housing (74) having an intake port (88, 90) located adjacent the heating element, an intake duct (92) disposed in the compression box (68), and a diffuser plate (86) disposed above the intake duct. The intake duct (92) has an inlet opening (106, 108) in fluid communication with the intake port (88, 90) of the compression box housing (74) and an outlet opening (110). The compression box assembly is configured to draw heated air into the compression box housing from the reflow oven chamber through the intake port and into the inlet opening of the intake duct and exhaust air out of the outlet opening of the intake duct to the diffuser plate. A method of distributing heated air within a reflow soldering oven is further disclosed.

摘要： A wave solder machine is configured to perform a wave solder operation on an electronic substrate. The wave solder machine includes 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, and a conveyor configured to transport substrates through a tunnel passing through the fluxing station, the pre-heating station and the wave soldering station. The wave solder machine further includes a flux management system configured to remove contaminants from the tunnel. The flux management system is 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. Methods of performing a wave solder operation are further disclosed.

摘要： A wave solder machine (10) includes a pre-heating station (20), a wave soldering station (22), and a conveyor (16) to transport substrates (12) through a tunnel passing through the pre-heating station (20) and the wave soldering station (22). The tunnel has a substantially oxygen-free environment. The pre-heating station (20) includes a pre-heater including a support frame assembly, and a heater assembly supported by the support frame assembly. The heater assembly is slidably coupled to the support frame assembly between an operational position and a non-operational position. The pre-heater further includes a seal disposed between the heater assembly and the support frame assembly. The seal provides a gas- tight seal when the heater assembly is in the operational position to prevent atmosphere from entering the tunnel thereby preserving the substantially oxygen-free environment within the tunnel.
