Abstract
A bath apparatusreserves a liquidas a heating medium and includes an input partition bath, a first intermediate partition bath, a heat partition bath, a second intermediate partition bathand a removing partition baththat are divided by gatesthroughand sequentially arranged in a direction in which a printed board assembly where components are loaded onto a printed board moves. The temperatures of liquids-and-in the input partition bathand the first partition bathare a preheating temperature. The temperature of a liquid-in the heat partition bathis a soldering temperature. The gateis gradually opened while the printed board assemblyis located in the first intermediate partition bathand before the printed board assemblyis conveyed into the heat partition bath. The liquid in the heat partition bathis mixed with the liquid in the first intermediate partition bath, and thus the temperature of the first intermediate partition bathis gradually increased to the soldering temperature. The temperature of the printed board assemblyis gradually increased from the preheating temperature to the soldering temperature.
