Identifying Resistors/Capacitors on the logicboard


I bought a damaged iPhone 5s and it looks like somebody already tried to fix it.

He/she installed a new sim card slot (what a mess since he/she used glue!) since

the iPhone 5s has a "searching..." problem. I guess it is the broadband ic, not the sim card reader. Anyway, i replaced the replacement a bit more professional.

I then inspected the pcb and found that some resistors/capacitors are missing. I guess this is the result of "bad soldering skills"^^.

Anyway, the problem is - i dont know the value of these components. I already tried to look the up at a schematic i have, but i looks like the schematic is not complete/correct.

I am looking for the following component:

One or two more parts are missing, but I already know their value ;)

Thank you in advance!

Oy...bad soldering skills indeed...and glue!?!

The iPhone 5S has a few different versions of the logic board. I looked at the 820-3382-A version.

The top component of the two is C103 (56 pF / 6.3V / 5% / package 01005). The bottom component is FL59, a ferrite bead (120 Ohm / 210 mA / package 01005).

Thank you very much! Can you maybe tell me where I can buy/download that schematic? thanks!


Just search Google "iphone 5S schematic", you should find it pretty easily. You can also sign up at GSMHosting, they're pretty much all there. also "sells" them.
