摘要： The present disclosure discloses a reflow oven, comprising a heating zone, a cooling zone, a barrier and exhaust zone, a gas exhaust passage, a gas exhaust power device, and a detection device. The heating zone comprises a heating zone inlet and a heating zone outlet. The cooling zone comprises a cooling zone inlet and a cooling zone outlet. The barrier and exhaust zone is located between the heating zone outlet and the cooling zone inlet. An inlet of the gas exhaust passage is communicated with the barrier and exhaust zone. The gas exhaust power device is disposed on the gas exhaust passage. The detection device is disposed on the gas exhaust passage and used for detecting parameters of gas in the gas exhaust passage, wherein the parameters of the gas reflect a blockage condition of the gas exhaust power device.

摘要： The present disclosure discloses a reflow oven for processing a circuit board, the reflow oven comprising a heating zone, a plurality of heating devices and a start-stop device. The heating zone comprises a plurality of heating sub-zones, the plurality of heating devices are arranged in corresponding heating sub-zones of the plurality of heating sub-zones, and each of the plurality of heating devices is configured such that a working temperature of the corresponding heating sub-zone is in a predetermined temperature interval. The start-stop device is configured to activate or deactivate the plurality of heating devices, and the start-stop device is configured in such a way that the start-stop device activates or deactivates the plurality of heating devices according to predetermined time intervals in a process during which the circuit board sequentially passes through the plurality of heating sub-zones, such that a working temperature of each of the plurality of heating sub-zones is in a corresponding predetermined temperature interval. The reflow oven according to the present disclosure can perform soldering and processing of large-sized circuit boards and prevent the occurrence of overheating in a hearth of the reflow oven.

摘要： The present disclosure discloses a reflow oven, comprising a heating zone, a cooling zone, a barrier and exhaust zone, a gas exhaust passage, a gas exhaust power device, and a detection device. The heating zone comprises a heating zone inlet and a heating zone outlet. The cooling zone comprises a cooling zone inlet and a cooling zone outlet. The barrier and exhaust zone is located between the heating zone outlet and the cooling zone inlet. An inlet of the gas exhaust passage is communicated with the barrier and exhaust zone. The gas exhaust power device is disposed on the gas exhaust passage. The detection device is disposed on the gas exhaust passage and used for detecting parameters of gas in the gas exhaust passage, wherein the parameters of the gas reflect a blockage condition of the gas exhaust power device. The reflow oven according to the present disclosure can ensure that the gas containing soldering flux is sufficiently drawn out from the barrier and exhaust zone, thereby ensuring the production quality of a circuit board and improving the qualified rate of the circuit board.
