I don't think U'll find out them in forum, bro.!!!
They r basic knowledge of mobile repairing
No everyone interesting to know deep more
Important thing, known how to operate tool, diagnose, repair, n all problem solved ..

All of them r main work'n voltage condition for processor.
PURX = reset voltage
VANA = voltage produced for itself (Power IC) that split out be all Vr voltage
Vcore n VcoreA = voltage for main IC (Processor)
A n No A just for different for the source, can be 1st IC power, 2nd IC power or make from regulator component.


Sorry.. for my bad English.!!!

I don't clear some what r u ask by those piece layout, bro ..
If U wanna know prof way, U must learn look with diagram
Layout just show position all part n point in diagram

The point is, if U want know the source some voltage
U must find way by diagram looking, not by Layout ..
Example VSIM N70. Diagram looking, it graft VSIM1 near X2700 (socket SIM)
n search their way, one to X2700, another one get in EMIF R2700 (Protector) n last one direct to VSIM1 from RETU
That means, we already known the source is RETU

As we known, N70 has 2 IC Power, RETU n TAHVO
