Xiaomi 10 No Puede Arrancar Causado Por Ca\u00edda Continua Da\u00f1o<\/p>\n<\/p>\n

\"\"<\/p>\n

Modelo:<\/strong> Xiaomi 10<\/p>\n

Anunciado:<\/strong> 2020, 13 de febrero<\/p>\n<\/p>\n

Fen\u00f3meno del defecto<\/h2>\n

The kid plays with the cell phone as a toy, after keep dropping it several times the phone screen turned to black and cannot boot.<\/p>\n<\/p>\n

Soluci\u00f3n de problemas<\/h2>\n

Place the cellphone on the heating pad to heat and separate.<\/p>\n

\"\"<\/p>\n

After seprating, we find the phone has not been repaired yet<\/p>\n

\"\"<\/p>\n<\/p>\n

Then remove the wireless charging coil and all the screws, then measure the voltage value on the battery.<\/p>\n

The battery voltage is normal<\/p>\n

\"\"<\/p>\n<\/p>\n

Then buckle the battery and test again, the phone still cannot be booted.<\/p>\n<\/p>\n

Then let’s check the motherboard<\/p>\n

First, let’s solder a wire for the positive DC power input connection<\/p>\n

\"\"<\/p>\n<\/p>\n

Then connect with the Fuente de alimentaci\u00f3n de CC<\/a> and trigger to boot<\/p>\n

\"\"<\/p>\n<\/p>\n

The boot current is 50mA only then drop to 0<\/p>\n

\"\"<\/p>\n<\/p>\n

Based on the repair experience, this kind of defect normally is caused by CPU poor soldering or the CPU relative buck voltage inductor poor soldering.<\/p>\n<\/p>\n

Proceso de reparaci\u00f3n<\/h2>\n

Let’s start from the simple part, to check if there’s any poor soldering inductor.<\/p>\n

Push the inductor around the PMIC with tweezers slightly, find there’s no loose inductor.<\/p>\n

\"\"<\/p>\n<\/p>\n

Then let’s remove the shielding cover on the power supply chips, well keep the removed shielding cover, as we will need to solder them back after repairing is done.<\/p>\n

\"\"<\/p>\n

Carefully check the components under the shielding cover again, everything is OK.<\/p>\n<\/p>\n

Then the next step, we should resolder the CPU chip to have a try, we should also remove the shielding cover first.<\/p>\n

\"\"<\/p>\n<\/p>\n

Let’s remove the upper layer of the CPU chip first<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n<\/p>\n

After that, remove the lower layer of the CPU<\/p>\n

\"\"<\/p>\n<\/p>\n

After removing the CPU, we can start to clean the pads on the PCB.<\/p>\n

Tips: Xiaomi Mi10’s CPU is not sealed with glue, so the pad cleaning is much easier, we just need to use the solder wick to remove and flat the tin pads.<\/p>\n

\"\"<\/p>\n<\/p>\n

It’s convenient for repair, but the CPU without glue sealing is not very stable, and the heat consumption effect is poorer.<\/p>\n<\/p>\n

OK, let’s continue to reball the two layers of the CPU.<\/p>\n

\"\"<\/p>\n<\/p>\n

\"\"<\/p>\n<\/p>\n

After resoldering, step by step, let’s resolder the two layers of the CPU to the motherboard.<\/p>\n

\"\"<\/p>\n<\/p>\n

The CPU resolder is finished<\/p>\n

\"\"<\/p>\n<\/p>\n

Assemble the phone temporarily to have a test, the phone can be booted normally.<\/p>\n

\"\"<\/p>\n<\/p>\n

Last but not least, let’s solder back the shielding cover, then assemble to test again to ensure all the functions are OK.<\/p>\n

\"\"<\/p>\n<\/p>\n

The phone can boot normally, and all the functions are tested OK after assembling.<\/p>\n<\/p>\n
