PROBLEM TO BE SOLVED: To develop a jet type soldering tank in which a soldering temperature in a tank can be maintained as uniform as possible, and at the same time, the service lifetime of the tank can be prolonged, and in addition, the reduction of operating costs can be also realized. SOLUTION: The jet type soldering tank has the following characteristics. At least the whole area on the lower side from the vicinity of a liquid surface level (L) on the outer peripheral face of the tank (1) and the whole area of the bottom face of the tank (1) are respectively covered with in the order of a heat conductive plate (2), a plane heater (3), and a heat insulating material, and made into a multilayer structure. A plane heater, in which temperature variations occur on the inner face being a heating face, is used as the plane heater (3). COPYRIGHT: (C)2005,JPO&NCIPI
