A soldering method for soldering an electronic component to a circuit board is disclosed. The soldering method includes placing the electronic component on the bonding portion of the circuit board with solder arranged between the electronic component and the bonding portion, placing a weight on the electronic component, and heating and melting the solder while pressing the electronic component toward the circuit board with the weight. The weight is spaced from the electronic component while the temperature of the solder is still high after the melted solder wets the bonding portion and the bonding surface of the electronic component and spreads out therebetween. |
