iPhone 4 Teardown

The teardown experience was amazing! To tell the truth, I have always dreaming of disassembling Apple’s products, thinking that its technical content and technological level are unparalleled, which is also the reason why I choose this product.

1- This is the initial state of the product.
2- First remove the battery, small screws and wirings.
3- Next remove the rear camera and speakers.
4- Lift the covered wirings and remove the lock button and handset structure.

  1. One of the parts I’m most interested in is the vibrator. I was first attracted by its shape, which looks like a cylinder with another half cylinder strung on top of it, and can be rotated around it. It works by using a CAM (eccentric device) to rotate inside the phone, resulting in vibration.

I compared it with the vibrators of other products and found that its volume is actually much smaller than the usual products. I believe that in the future, with the improvement of the accuracy and requirements of mobile phone manufacturing, the production of vibrators will be more compact and precise.


2. The other part I’m interested in is the wiring. Because when I disassembled the parts, I actually sighed that all the lines were very precise and neat. It is hard to imagine how they are produced and assembled, and their role is so crucial in the production of mobile phones that I look forward to learning more about them and even learning to use them.

” If you do something and it turns out pretty good, then you should go do something else wonderful, not dwell on it for too long. Just figure out what’s next.”

Looking forward to the next!
