could I find a data sheet of iPhone 4s logic board?
hi everybody!
I repair i device since a few years ago but it was just for basic fix as change a screen or dock flex, camera... nothing hard...
but now I try to fix motherboards problems, change power ic, screen connector, wifi/bluetooth ic...
I have a lot of iphone 4s logic boards with missing resistors and capacitors situated between the lcd connector and the wifi/blue-tooth ic see picture:

I'd like to know how could I identify them, their names, their functions (capacitor or resistor?), their values, where could I buy this small "things" and if I can find data sheets of iphone motherboards?
I know, I have a lot of questions in one time but I'm checking on Internet since a few month without any results, and my location ( Dominican republic) is not a real advantage. So I'm sure that your answers will be very helpful
thanks a lot!

Thanks a lot for your answers!
I bought a smd rework station a few months earlier. I use it to remove ic from boards but for soldering I prefer use an oven with a 130*C solder paste, works fine, for my practice, I used two old CDMA i4, killed first (when desolder the ic a part of the circuit get out with the chip) and the second still works fine (I removed the power IC to change it on both of them)... I also tried to solder resistors and capacitors with the iron of my station but I can't... for me it doesn't work but in oven it does... Just a bit hard to place component on board...
I will check on mouser.com that I didn't know, thanks for this tips! Does the size of resistor or capacitor change the value?
I just found schematics of i3,i3gs,i4,i4s and i5 it will be very helpful for my work!
Thanks a lot for your help and if interest for someone I can share my work and pictures of it.

mael, it is always good to make some guides from the repairs. This is where you would post guides for the 4S http://www.ifixit.com/Guide/new/Device/i... Does the size of resistor or capacitor change the value? No it does not, but for your repairs you have to change the broken components with alike components. Always make sure that the package i.e. 01005 etc are the same when you order your parts. The "oven" may work for some of the parts, but it will not work for the smaller resistors or capacitors. Practice plenty with your reflow station. Good luck to you.
