The iPad Pro series of devices are harder to troubleshoot sue to the lack of schematics but there are a quite a few micro-soldering repair shops that can and do fix these devices. You don't really tell us much about how and why the iPad failed so it's hard to give you any kind of diagnostic. You should update your question with more details.
As for repair, look locally for a reputable shop that does micro-soldering repairs. Ideally, you want to find someone local but good workmanship trumps locality. There are many shops worldwide that do this so you shouldn't have any problems finding them. Talk to them and ask how they do their work. Focus on troubleshooting, as opposed to shotgun replacement, and good practices like proper cleaning of boards once completed etc.
If you can't find one locally, then consider mail-in repair. There are several reputable micro-solderers patrolling this forum.

Thanks lot,
so you think that for the detected low amperage , is reasonable thinking it's because we had some broken circuit and it's required a microsoldering?
