Here are my photos from the teardown of a slide-open Samsung mobile phone. Enjoy my overly detailed record!
I removed the backing battery cover as well as the battery, which revealed six miniature Philips head screws. After removing these screws, I was able to remove the plastic panel covering the circuitry as well as the buttons.
Next, I noticed a single screw holding a smaller microprocessor board near the top of the phone. I removed this next, and believe it to be the headphone jack.
I moved on the top half of the phone — the screen. Two screws were removed, allowing the screen to come apart and reveal the digitizer — the component which converts our analog actions (press, swipe, etc.) into digital signals. Also seen in the photos (and labeled) are the camera, camera flash, vibration motor and headphone jack.
Next, I peeled off the “keyboard”, which turned out to be a sticker placed above capacitors. Also visible is a spring clip which gives the phone it’s quality snap back and forth open/close feel.
Lastly, I removed the main circuitboard for disassembly. I could not find data sheets on all the components as the phone is a bit outdated, so I did my best to guess what they were. Also, I believe this plastic phone was almost entirely constructed using injection molding techniques. The exceptions are of course the electronics as well as the screen.
Here is the final teardown photo. I had a blast!
