Abstract
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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
