Use this guide to replace a faulty logic board in your iPhone 5s.
It's important to note that each iPhone's logic board and Touch ID fingerprint sensor are paired at the factory, so replacing the logic board will disable Touch ID unless you also install a replacement home button that has been properly paired to your new logic board.

-
Power off your iPhone before beginning disassembly.
-
Remove the two 3.9 mm Pentalobe screws from either side of Lightning connector.
-
-
-
If your display glass is cracked, keep further breakage contained and prevent bodily harm during your repair by taping the glass.
-
Lay overlapping strips of clear packing tape over the iPhone's display until the whole face is covered.
-
-
-
Regardless of the tool you use, you need to be sure you pull up the entire display.
-
If the glass begins to separate from the plastic, as shown in the first image, slide a plastic opening tool between the plastic frame and the metal phone body to pry the metal clips out of the case.

-
-
Close the handle on the iSclack, opening the suction-cup jaws.
-
Place the bottom of your iPhone in between the suction cups, against the plastic depth gauge.
-
The top suction cup should rest just above the home button.
-
Open the handles to close the jaws of the iSclack. Center the suction cups and press them firmly onto the top and bottom of the iPhone.
-
-
-
Hold onto your iPhone securely and close the handle of the iSclack to separate the suction cups, pulling the front panel up from the rear case.
-
The iSclack is designed to safely open your iPhone just enough to separate the pieces, but not enough to damage the home button cable.
-
Skip the next three steps and continue on Step 9.
-
-
-
If you don't have an iSclack, use a single suction cup to lift the front panel:
-
Press a suction cup onto the screen, just above the home button.
-
-
-
While holding the iPhone down with one hand, pull up on the suction cup to slightly separate the home button end of the front panel from the rear case.
-
With a plastic opening tool, gently pry the edges of the rear case down, away from the front panel assembly, while you pull up with the suction cup.
-
-
-
Pull the plastic nub to release the vacuum seal on the suction cup.
-
Remove the suction cup from the screen.
-
-
-
Open the phone just enough to reveal the metal bracket covering the home button cable.
-
Only the phone's original home button assembly will be capable of using the Touch ID functionality. If you rip the cable, installing a new home button will only restore ordinary home button functions, not the Touch ID features.
-
Use the tip of a spudger to push the bracket free and remove it with tweezers.

-
Open the display to about a 90º angle, and lean it against something to keep it propped up while you're working on the phone.

I have the same question, where do I get a replacement board? I am a little wary of ebay from china.
Also what is involved in getting all the small metal bits onto a new "bare" board? Since that is the only way I am able to find a logic board.

You can’t buy the logic boards from iFixit (unless second hand), instead you will have to replaceit with another from a matching iPhone model and install it into your phone.
