PROBLEM TO BE SOLVED: To provide a new soldering method capable of efficiently heating solder by utilizing a heat sink equipped onto a circuit board, when soldering an electronic component onto the circuit board. SOLUTION: As the circuit board 11, a cooling circuit board is used. In the cooling circuit board, a metal heat sink 15 having a refrigerant channel 15a is integrated with the backside of the ceramic substrate 14 having a metal circuit 13 on the surface. A semiconductor device 12 is arranged while a solder sheet 33 is interposed on the metal circuit 13, a weight 35 is placed on the semiconductor device 12, and the solder sheet 33 is heated while being pressed by the weight 35. When the solder sheet 33 is heated, a heated heating medium flows in the refrigerant channel 15a. After solder is fused, heating is stopped. After that, a cooling medium flows into the refrigerant channel 15a for cooling the circuit board 11 and the solder. COPYRIGHT: (C)2007,JPO&INPIT
