LG V20 USB-C Port Micro Soldering
A charger port is arguably the most used part of a mobile device. This often invites dirt, lint and damage from many repeated connections.
The LG V20 uses a USB-C connector, technically known as USB Type-C, is a 24-pin USB connector system, which is distinguished by its rotationally-symmetrical connector.
The USB-C interface allows for a more rugged and faster throughput, but is still susceptible to failure, damage and replacement.
- To replace the LG V20 USB Type-C charger/data connector we first need to gain access to the motherboard. This is done by removing the back battery panel, followed by removing numerous screws holding the frame together.
- Once the back housing is removed we expose the motherboard and can remove it from the frame.
- Once we inspect the port under a microscope we can see the damaged and dirty pins.
- We then need to cover any heat sensitive components such as the nearby LCD data filters and fpc connector for the screen/digitizer with tape. We also use a heatsink such as a copper penny to cover the adjacent microphone to avoid damage.
- After using a hot air station set at about 410 degrees celsius aimed at the charger port we are able to melt the solder and pull away the port.
- After cleaning (wicking) and applying new leaded solder to the port we are ready to install the new port.
- After replacing the charger port it is important to connect the phone to a USB ammeter to verify the current draw to be sure the port is properly installed and able to function as normal.
- We can see the phone is pulling 1.53amps of current which is a normal value and at this point we are sure the phone has been repair and is properly working again.
