HTC 10 Evo 64 How to Disassemble

Used tools

1.

The name of the new BlackBerry tablet. the PlayBook. is at the same time associated with entertainment and literature.

Specifications:

  • 7-inch touch screen with multi-touch recognition (Multitouch)
  • 1 GHz dual-core processor TI OMAP 4430
  • 1 GB RAM
  • two HD cameras (front with a resolution of 3MP and rear with a resolution of 5MP)

It is strange that this tablet does not support mobile broadband.

2.

As we look at the tablet, the front camera observes us through the peephole. The white dot to the left of the camera is the status LED.

If you take the PlayBook in your hands, the device impresses. The metal frame around the glass front panel, the rubberized case and the generally impressive design almost make you forget about dubious software.

The small PlayBook charging dock connector resembles one of the best features on Apple laptops.

3.

We insert a plastic tool for opening the cases into the gap between the frame and the front panel and pray to the gods of electronics so that the glass does not crack.

Fortunately, thoughtfully laid out latches around the perimeter of the plastic rear panel securely fasten it to the front panel without screws and glue.

4.

Having disconnected latches on perimeter, it is possible to remove the back panel.

Unlike other popular tablets, the main components of the PlayBook are not attached to the back panel, but to the display module.

The PlayBook has a 20 W / h battery, which is slightly less than the iPad 2 (25 W / h) and Xoom (24 W / h).

5.

Now you can unscrew a couple of screws from the battery connector with a # 00 Phillips screwdriver.

Then we unfasten the battery connector.

We continue to unfasten all other connectors on the motherboard.

6.

Then we unscrew a couple of screws from the motherboard using a Phillips # 00 screwdriver.

In the shining rays from the sky BlackBerry (not visible in the photo) remove the PlayBook motherboard.

Many thanks to my colleagues at Chipworks for helping me identify PlayBook components!

Let’s pay attention to the front panel again.

The right speaker is supported by two screws and is connected to the motherboard by pressure contacts. Unscrew the screws with a # 00 size Phillips screwdriver.

Each speaker module has 2 separate speakers, i.e. there are 4 of them.

10.

The left speaker is simply removed from the steel middle backplane, but is still attached to the battery.

The middle backplane is attached to the front panel with several screws.

eleven.

We remove the middle backplane, on which the battery, the left speaker and antennas are installed.

This design provides quick access to the front panel and LCD display. the components that break most often in mobile devices.

The antennas in the PlayBook are built into the rear panel and speaker modules and are attached to the antenna cables by pressure contacts.

12.

The camera module is easily removed from the slot.

The front camera, rear camera and control buttons are combined into a single module, which greatly increases the cost of replacing a broken power button or volume control.

thirteen.

The headset jack cable is secured with a metal clip.

The right microphone is also attached to this module.

Two microphones are apparently used to subtract background noise.

14.

We unstick the left microphone from the front panel.

Having removed the rubber cap and the dust screen, you can read the inscription: S233 7252.

fifteen.

After unscrewing the remaining screws, you can remove the LCD panel from the front panel module. This small 7-inch panel has a resolution of 1024 x 600 pixels.

Taking a closer look, we find that the frame around the glass front panel is made of magnesium. a strong but light metal. Magnesium is used in many mobile devices due to such qualities.

In the following picture, you can see the Cypress CY8CTMA3 Multi-Touch All-Point TrueTouch ™ touchscreen controller. It is attached directly to the digitizer cable.

16.

Easy repair BlackBerry PlayBook: 7 out of 10 (10 points mean maximum simplicity).

  • The back panel is easily removed by prying with a plastic tool.
  • The LCD is not soldered to the front glass, which makes it cheaper to replace broken glass.
  • To replace the glass, you have to disassemble the entire device, but the middle backplane with all components on it is easily removed.
  • Other components (cameras, headset jack, etc.) are easily removable. However, usually 2-3 components are fixed on loops, which makes repair of one of the components more expensive.
  • To replace the battery, you will have to remove the motherboard. it is glued to the middle backplane.
  • A metal frame is glued to the glass front panel, and if the glass breaks, you will have to peel off the frame by heating with a hairdryer.
