Abstract

See full text

The present application discloses a reflow oven and the operation method thereof. The reflow oven can operate in air mode and inert gas mode. The reflow oven comprises a heating zone, a blocked exhaust zone and a cooling zone. The reflow oven further comprises a first pipeline, a second pipeline and a third pipeline. When the reflow oven operates in air mode, external clean air is delivered to the heating zone and is discharged from the heating zone and the blocked exhaust zone. When the reflow oven operates in inert gas mode, an inert gas is delivered from the blocked exhaust zone to the heating zone and is discharged from the heating zone. Satisfying the accurate temperature profiling necessary for reflow processing in the operation atmosphere of air or an inert gas, the reflow oven in the present application can effectively discharge volatile pollutants to reduce the number of follow-up services and maintenances. In addition, the reflow oven in the present application can save the expensive inert gas.
