ABSTRACT:
A heat conducting apparatus includes an air guide hood and a heat conducting device. The air guide hood is connected to a hot air supply source for delivering hot air, and includes an air outlet for exit of the hot air. The heat conducting device is disposed at the air outlet of the air guide hood, and includes a contact wall spaced apart from and disposed below the air outlet for contacting a soldered component, and a surrounding wall extending upwardly from the contact wall and connected to the air guide hood. The contact wall and the surrounding wall cooperatively define a space for guiding the hot air. The contact wall conducts the heat to the soldered component so as to melt tin solders between the soldered component and a circuit board, thereby reducing any adverse effect on other electronic components or good chips on the circuit board.
