Abstract
A soldering apparatus includes a cooling zone, upper and lower vent holes, an external channel, a blower unit, a heat exchanger, a pair of bypass channels, and a ventilation plate. The vent holes are provided, respectively, above and below a pair of rails configured to transport a board in the cooling zone. The external channel connects the vent holes with each other outside the cooling zone. The blower unit causes gas in the external channel to flow through the upper vent hole, the cooling zone, and the lower vent hole. The heat exchanger is provided in a lower opening linked to the lower vent hole in the cooling zone. The pair of bypass channels deliver gas above the pair of rails to the lower opening while bypassing locations of the pair of rails. The ventilation plate is provided in a space formed between the pair of bypass channels.
