Because it is directly connected to the CPU, under normal circumstances, it will not be repaired by default, because if the CPU is damaged beyond repair, and the mobile phone can be used normally at present, it is not recommended for users to take such a high risk to move the CPU, but at present, other functions of the mobile phone are normal, and we only have to redo the CPU for repair.
