This time Samsung's new flagship smartphone Galaxy S5 does not have a lot of movements on hardware configuration, and the opposite is to join some more detachable applications, such as heart rate monitoring, waterproof and dustproof, fingerprint identification, super power mode and more comprehensive Camera function, etc. After the Korean startup S5, Ewistech is fully "examined" her "outside", "test" over her camera and software, is the time to promote EWISETECH laboratory dismantling analysis. .
The first step is separated from the back shell, Samsung Galaxy S5's level of protection is IP67, but still uses the design of the removable shell and replaceable battery (common waterproof dustproof mobile phone usually uses integrated body design). There is a rubber ring on the rear shell, and the seal ring "circs", the contacts, and the key circuit part of the body "is separated from the outside, and the purpose of waterproof.
The second step is removed.
The third step is to block the road to stand - the split screen. Unlike common demolished rear shell and then separating the circuit motherboard. After the engineer's observation and attempt, the separation of the screen and the fuselage is the key to the switch of S5.
Due to the realization of the waterproof and dustproof characteristics of the fuselage, the stack between the screen and the body is very tight, and the heat is separated, and the bonding is difficult to understand, it has been disassembled, and it has been one and a half hours. The power of nine bulls two tigers? Non-also, it is really that Bailian steel does not have a softness, non-patience and skill.
Don't think that the screen and the body can act rashly. In fact, the screen panel assembly and circuit motherboard are actually "broken" - Home key flexible soft cable is also connected to the circuit board, completely separate needs to open both. Connector.
Next, you can really pine up, fourth step - remove the fingerprint recognition / HOME key assembly, and the component is adhesive on the screen panel by sealing.
Step 5, the circuit motherboard and the back cover are separated. There is finally no sealant, and the separation of the infrared induction module needs to be aware of this step.
In the sixth step, the two screws of the fixed motherboard are removed, remove the two RF coaxial lines, slightly heaters the circuit motherboard (there is still a layer of adhesive between the two)
Step 7: Remove the front and rear cameras on the motherboard.
Remove the shield, the main IC of the circuit board:
Eighth steps, the vibrator and volume button contact flexible soft cable on the split medium.
Be
In the ninth step, the headphone connector, speakers, readers, antenna modules, power / volume buttons modules, and power / volume buttons modules are split.
Finally, I will come to Zhang S5 "Family Fu".
The main difficulty of the entire dismantling is that the screen is separated from the fuselage, which is a big challenge for subsequent repair.
