Did you know we spend approximately 30% of our time on our phones? I’m from team 9090A and I am filing my report on the iPhone 5s. I’m going to tell you about parts i found, what each part dose, and what i learned. I’m taking apart this device because I am interested on how Apple makes such a complicated item fit in the palm of your hand. It’s about 5 by 2.5 inches, has a 4 inch display, and has a finger identification sensor inside into the home button. I found several pieces while taking apart my device: a Li-ion (lithium ion) battery, 2 different cameras, as well as 2 different speakers. I also found the Lighting Connector, which is at the bottom of the phone and includes the charging port, and the speaker plug. On the Wifi Module, where the bulk of the circuitry is, I found many IC’s (integrated circuits) which includes the M7, A7, memory storage, multiple Qualcomm integrated circuits, and a TI touchscreen interface. Each part has a unique role in the phone, and how it functions. The battery supplies stored power, to the phone, that’s gathered by the Lighting Connector. The A7 is the the heart of the phone, and the M7 is her sidekick. The A7 is the central processing unit (CPU), and the M7 gathers sensor data. Qualcomm has 3 IC’s that are in the iPhone 5s, a LTE modem, a transceiver, and a PMIC (power management IC). The memory storage IC was made by SK Hynix, which is a semiconductor suppling company like TI. The speakers are located next to the lighting connector at the bottom and produces sound by pushing air to create different sounds. Their was only one TI part, it a touchscreen interface, which is the IC used too tell where your finger is touching the screen. It is close the the top corner of the Wifi Module. It’s labeled with the numbers 42W658P and 343S0645. To conclude this report I learned about multiple IC creators like, Qualcomm and SK Hynix. I also learned about how speakers work. Knowing this might help me later when i get an engineering degree. Apple’s IC are so small, that’s why they can make their devices so small. I am hypothesizing that future iPhone’s will have similar design websites that i used alot https://www.youtube.com/watch?v=IAq7X4ytm-w https://www.ifixit.com/Teardown/iPhone+5s+Teardown/17383
