Description

Technical Field

[0001] The utility model relates to the technical field of curing oven equipment, in particular to a device for preventing oil pollution backflow of an exhaust pipe of a curing oven. Background Art

[0002] When electronic components are being cured, the curing agent will volatilize in a gaseous state after promoting the curing of the encapsulation layer of the electronic components. The gaseous curing agent will be drawn into the exhaust duct above the curing oven.
