USB port connector and 5 soldering points
There are five soldering points on the board that is connected to the USB port pins. However when I see those ripped off the board, I see some of the soldering points are detached with the port's pin. However, yet when I put a new port on the board, sometimes it works only with 3-4 connections.
But when I put another port on with one missing point (2nd from right), customer says it is not charging the battery even though the light comes and screen shows battery charging indicator. so I would like to know if anyone know about how many and which pin must be connected to charge the battery?
Thanks in advance.
Is this a good question?
