手順14

Desolder the 12 leads to remove the connector from the circuit board.
There are ten leads in two parallel rows and two larger leads below them.
The satellite antenna is a thru-hole-mounted device. You must apply heat to each soldered pin individually and pull them out of the holes while the solder is molten.
The solder material, pins, and any surrounding material will get VERY hot while melting the connections. Do not touch any metal parts during the desoldering process and give the device time to cool off once you’re finished. It may also be good to take breaks so that the electronics aren’t kept hot for extended periods of time.
