<p>A soldering apparatus has a sealable container which accommodates a circuit board therein, weights disposed immediately upon semiconductor devices to press the semiconductor devices toward the circuit board, and high-frequency heating coils causing the weight to generate heat due to electromagnetic induction. The high-frequency heating coils are disposed away from the weights. The heat generated in each weight is applied to a plurality of joint sites of the circuit board, thereby soldering the semiconductor devices to the joint sites. As a result, efficient heating is realized while simplifying the configuration of the apparatus.</p> |
