Andrea – Tearin it Down (a.k.a. Teardown) – Cell Phone

This is the same model of the cell phone I used in middle school.  I wish I could say I had fond memories, but this was the one cell phone I completely destroyed, even before this project.  That being said, prying it apart was way more difficult than I anticipated…

Lookin’ Good.

Nothing too drastic.

Pretty standard.

The cool little silver bubbles [right photo] are actually the buttons(?!)

The back looks really complicated.  I have no idea what’s going on.

This is where the struggle got real.  So real.

Arjun Kalyanpur – Teardown – Samsung Sliding Mobile Phone

Hi all,

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.

I then removed what I believe to be the speaker as well as some button controls, seen below:IMG_9115IMG_9127 copy

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 I could not find data sheets on all the components as the phone is a bit outdated, so I did my best to guess what they were.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.

Tear Down – Motorola Droid Phone

This is my post for the teardown assignment.  My teardown object of choice was a Motorola Droid cellphone.

Taking apart the phone was relatively simple.

The tiny screws gave me some trouble, but it was the tiny tiny screws that were the most difficult.  I could not find a small enough screw driver, so I tried drilling it with a dremel.

I wanted to remove the LCD screen.  After failing to remove the screws, I tried prying it off and that is when I cracked the screen.  This is when I began to consider my safety and called the tear down complete.

A list of the removed parts (with pictures):

This was a fun project.  I enjoyed taking an object that was once precious to me and just tearing it apart and destroying it (for educational purposes).
