Battery, SIM card, and micro-SD card removed

With the battery, SIM card, and micro-SD card removed, we can begin removing the plastic case.

Remove the top and bottom bezel

The Dell Streak’s plastic case is held to the front panel assembly with five T5 Torx screws. Unfortunately, the screws are hidden under the rounded, plastic bezels located on the top and bottom of the Streak. We will need to remove these bezels before removing the screws.

Removing the top plastic bezel

Using a thin metal blade or plastic case-opening tool, gently pry the first bezel loose. The thin plastic piece is held on with double-sided tape. You should be able to remove the bezel and leave the tape stuck to the plastic case. This will allow you to reattach the bezel when you reassemble the device.

The top bezel removed

Two T5 Torx screws are located under the top bezel.

Removing the bottom bezel

Using the same technique you used earlier, pry loose the bottom bezel. But take care. The bottom bezel houses the Dell Streak’s main control buttons and is attached to the device with a thin ribbon cable. At this point, you don’t need to remove the cable. Just lift the bezel up enough to reach the three T5 Torx screws located underneath.

Prying loose the read case

With the five T5 Torx screws removed, gently pry the rear case free from the front panel assembly.

Rear case - Internal and buttons

Be careful when separating the rear case from the front panel assembly. The power, camera, and volume up/down buttons are not fastened to the case and will likely fall out.

Rear case removed

With the rear case completely removed, we get our first look inside the Dell Streak. While the 5 megapixel camera is clearly visible at the top of the device, most of the main PCB and chips are hidden. We’ll need to remove the main PCB for a better look at the Streak’s hardware.

Remove the internal plastic bezel

There is a small plastic bezel attached to the bottom of the main PCB and front panel assembly. You should be able to pry this loose using a thin metal blade or plastic spludger.

Thin metal strip

This thin metal strip is attached to the internal plastic bezel with a bit of weak adhesive. You should be able to pry the strip loose from the bezel without harming either component.

Removing the camera connector

Before removing the main PCB from the front panel assembly, we must remove the various component connectors. We’ll start with the connector for the front-facing camera.

Front-facing camera removed

When disconnected from the main PCB, the front-facing camera can be pulled away from the front panel assembly.

Disconnecting the 5 megapixel rear-facing camera

Next, we’ll disconnect the Dell Streak’s 5.0 megapixel, rear-facing camera from the main PCB.

Disconnecting the touchscreen connector

After disconnecting both camera connectors, we’ll turn our attention to the touchscreen connector and control button connector.

Hidden touchscreen connector

The main PCB connector for the touchscreen is located under a square, rubber cushion located directly below the rear-facing camera’s connector. There are two chips located on the touchscreen connector–the Pixcir Tango S32 Capacitive Touch Controller IC and Atmel ATmega168P 8-bit AVR microcontroller.

Gently lift up the gate on the connector and pull the ribbon cable away from the main PCB.

Separate the touchscreen cable from the metal shield

The touchscreen’s ribbon cable is attached to the metal shield beneath it with a small amount of adhesive. It may take a bit of effort, but you should be able to separate the cable from the shield without damaging the cable or the circuits connected to it.

Disconnecting the control button cable

Lastly, disconnect the cable for the Dell Streak’s control buttons from the main PCB.

Ready to remove the main PCB

With all the connections removed, we’re ready to lift the main PCB away from the Dell Streak’s front panel assembly.

Front panel assembly

The Dell Streak’s LCD is permanently attached to the front panel’s Gorilla glass. You could pry the display and glass away from the front panel assembly, but they are joined with extremely strong adhesive and there’s really no reason to do so at this point as it would likely damage one or both of the components.

5.0 megapixel, rear-facing camera

At the top of the front panel assembly is the rear-facing camera and most of the ribbon cables.

Main PCB with metal shields - Top

Nearly all of the chips on the Dell Streak’s main PCB are covered by thin metal shields. We’ll need to remove the shields to see the chips underneath.

Main PCB with shields removed

The three shields that cover most of the Dell Streak’s chips should pop off with a little effort.

Snapdragon processor, Analog Devices HDMI/DVI Transmitter, and Hynix memory

Under the first metal shield is the 1 GHz Qualcomm Snapdragon (QSD 8250) processor, Analog Devices Low Power HDMI/DVI Transmitter (ADV7520), and Hynix NAND-based MCP ( a combination of NAND Flash and mobile SDRAM – H8BES0UU0MCR).

Under the last metal shield is another Qualcomm chip. A TriQuint Semiconductor TMQ7M5012 Quad-Band GSM/GPRS/EDGE-Polar Power Amplifier Module is located above it.
