  • Edit: the correct temperature is almost 180-200 °C because around the chip there is a little black protection that can go under the chip.

  • Set a low air flow: 1 or 2 (on a 1 to 7 scale).

  • Now, doing circular movement, you have to reflow for 4-5 minutes.

  • Be careful to reflow only the Wi-Fi chip and not any of the surrounding ICs or circuits.

  • After 5 minutes, gradually decrease the temperature from 200 to 0 °C.
