REFLOW FURNACE

Abstract:

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.
