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.
  • 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.

备注:需要用180~200℃的温度对芯片周围的黑胶进行处理。

选择风速:1档或者2档(适用于有1~7档的风枪)。

在芯片上方绕圈来回加热大概4~5分钟。

注意只需对WiFi芯片进行加热,不要对周围的芯片和电路加热。

5分钟后,将温度从200℃降到0℃。
