The outer skin of iPhone 5s has three colors: silver, golden and space
grey. It is allocated with A7 Chip, Touch ID, iSight camera with 8 million
pixel sensor and IOS 7.
iPhone 5s is used Apple’s own unique Pentalobular screw, using common
screw driver cannot dissemble. It needs Apple’s special tools.
After dissemble the screws, use sucker to
spare apart the screen and back cover so that we can check the inside
components.
Pay special attention
to the disassemble: be careful to taking the screen apart from engine body because the iPhone 5s’ interior has a cable which is connected Lighting connector with
Touch ID, or will pull out by overexertion.
The Touch ID is connected with the Home
Button by wire cable. While, other parts inside iPhone 5s are not different
from the iPhone 5, the only difference is that the battery of iPhone 5s is not
acquired label with battery detachable tags.
Begin to tear down
components. The battery is stick firmly on backboard by two big super glues and
very difficult to take apart. This is the reason why Apple removes the tag of
battery dis-assembly. Maybe the “s” in iPhone 5s means “stuck”.
Next step is screw out the shield case on the internal
main board of iPhone 5s. This step helps us to take battery module easily from
iPhone 5s.
Now remove iPhone 5s’Retina screen. It has 326 ppi pixel densities.
There is no difference between iPhone 5s and iPhone 5’s screen.
Touch ID is consisted of a bunch of small
capacitors, which called CMOS chip. As time goes by, the sensitive of Touch ID
will be reduced by using frequency.
iSight camera’s sticker is tagged with
DNL333 41GRF 4W61W, which is similar with iPhone 4’s camera. According to
informed source, we can see that the camera supplier is Sony.
The logic main board’s
model specification tag is very small. To know the specification, you should be
assisted by microscope and chip instruction. Some components have specification
on them.
The Wi-Fi chip looks
like Murata's 339S0205 (based on Broadcom's BCM4334).
We have disassembled 16G and 64G versions of iPhone 5s main board and finds
out has little differences. Maybe their main-boards are from different manufacturers.
The storage chip is
supplied from SK, the model is H2JTDG8UD3MBR. PM8018 RF – RF Power Management
Chip is from QUALCOMM. Other chips originate from Texas Instruments, Broadcom, Triquint,
and Skyworks and so on.
But most of them are from Skyworks and Avago.
On the other side of logic main board, it shows us heavyweight chip components,
includes A7 Processor and Baseband Processor from QUALCOMM, etc.
The closed-up photo of A7 Processor—This is Apple's brand new 64 mobile Processor. It is only applied on
iPhone 5s and its capacity is twice as A6. Nevertheless, the structure of A7
Processor still is ARMv7, not special design
for ARMv8 （64 Processor).
