Hello. I have a problem with the flooded iPhone 7, it had a short circuit of 0.350a I was able to remove it now it is 0.000a after turning on nothing happens and stands at 0.060-0.080a. Have any ideas?
Questa è una buona domanda?

you need to clean it using isopropyl alcohol. that will involve completely disassembling it.
Sostituzione case posteriore iPhone 7 (you do not have to replace the rear case, but this guide will go over complete disassembly.

pcb I already cleaned in an ultrasonic cleaner. A few capacitors fell in and there is no pmbb layout because it was short

halo cześć,
0,06A przy starcie wskazuje na niski bilans energetyczny. W takich przypadkach warto przestudiować linie główne zasilania. W większości przypadków, jeśli ich parametry mieszczą się w normie szukałbym “korka” za PMU. Sprawdź porty LDO z MPU i CPU razem z liniami SOC. Niewiele dalej, bo od 0.09 zaczynają się spięcia pod procesorem, spowodowane przegrzaniem 7-ki przy zdejmowaniu shield’ów.
pozdrawiam,
