How to disassemble the tablet

We all use tablets for different purposes, and usually there are no difficulties when using them. But sometimes there is a need to replace individual components. For example, the battery has deteriorated due to prolonged use, or the display has broken. In this case, contacting a specialist is quite expensive. This is also impractical if you live in a small town. Therefore, it is much easier to find out how the tablet is disassembled in order to make simple repairs yourself. Of course, each model is designed differently. But in this article we will provide you with a generalized tablet disassembly diagram. After familiarization, you will be able to generally understand how this device works.

What you will need during disassembly

Screwdrivers

This is the most necessary thing, since without them it is impossible to carefully open the tablet. You can, of course, use a knife. But then there is a high probability of damaging the screws. A set of screwdrivers is inexpensive. It can also be used to disassemble other devices.

Plastic spatula

She is required for detaching the back cover and other elements. It is also convenient for disconnecting cables on the board.

If you don’t have such a spatula, it doesn’t matter.

Advice! An unnecessary plastic card can replace the spatula. It is advisable to grind one edge down on a whetstone. This will make it much more convenient to disassemble the tablet.

Soldering gun

This device is used when soldering small board components. It can also be used to separate the touch part of the screen, since in most cases it is glued with glue.

Thin knife

These tools are convenient for working with components that you could not separate with a regular knife. Its main advantage is its thin blade, because it can get to hard-to-reach places.

Wire cutters

When disassembling, you most likely will not need this tool. But in some cases, the manufacturer glues some parts so tightly that it is impossible to do without such a tool. Before using wire cutters, you should definitely think about whether you can later return the bitten off component to working condition.

Tweezers

We recommend picking up almost all small parts with tweezers., because, firstly, it is much more convenient than doing it with your hands. Secondly, if you take the board components with your hands, sebum from your fingers will remain on them. Although this is not dangerous for all components, we still would not advise you to take risks.

Scotch

It will be useful to us already at the assembly stage, since some cables, microcontrollers, and touchscreens are glued with tape.

How to open the tablet

First of all, when disassembling the tablet, the back cover is removed. After this, the main parts will appear in front of you: board, battery, etc. Now we will tell you how to properly dismantle the back cover.

Removing the cover

Many tablets have slots on the side for SIM cards and a flash drive. They are closed with special caps; they should be disconnected first.This is done to make it easier for us to remove the cover.

Next, you should unscrew all the screws located along the edges that secure the cover. Be sure to check the slots for flash drives and SIM cards. Often additional fixing screws are located in these places.

Important! We recommend placing the screws for attaching the lid into a plastic bottle cap. When you unscrew the tablet board, these screws need to be placed in another cover.

This is done so as not to confuse them. Because if you tighten other screws, you can damage the threads.

Removing the cover

Next, using a plastic spatula or card, you need to pry off the latches of the rear wall. To do this, place the tablet with the screen facing you. Then Carefully insert the spatula into the gap between the body and the cover. You need to insert the scapula until you hear a characteristic click.

Then the spatula must be slowly moved along the body so that all the latches come unfastened. When removing the cover, make sure that there are no wires or cables holding it in place. If there are cables, then you need to use a spatula to pry the lock up. After this, you can remove the cable and put the cover aside.

Disassembling the tablet

After removing the cover, further disassembly can be carried out. We will tell you how to disassemble the device.

Disabling loops and wires

• Carefully inspect all cables and connectors on the tablet's motherboard. Pay special attention to the type of fastening, in this case, when disconnecting you will not damage the cable.
• Using tweezers, disconnect all cables from the motherboard. The easiest way to detach is the vibration motor, SIM card slots and flash drives, microphone, speakers, aux jack (for connecting headphones), and camera.
• If the cable is glued to the board, then first of all you need to warm it up with a soldering hair dryer so as not to damage it. A temperature of 60° will be sufficient. It is not necessary to warm it up too much, as some components are sensitive to high temperatures.

Attention! Be sure to record the order in which you disconnect components and cables. Then you can assemble the tablet in the correct order.

Disconnecting the battery

Unlike smartphones, the battery in tablets is almost always non-removable. It is connected using several wires. At the end there is usually a connector that connects to the motherboard.

• First, disconnect the battery connector from the motherboard. Only after this can you unscrew the battery mounting screws.
• If it is glued with double-sided tape, you will have to peel it off with your hands.
• The use of a soldering gun is not recommended. Since heating a battery is a rather dangerous activity.

Removing the motherboard

When you have disconnected all components and cables, then it is the turn of the main circuit - the motherboard. This is the main part, as it houses the processor, graphics accelerator, RAM and other important chips.

• Make sure all cables are disconnected. Then unscrew the screws securing the board. Now you can remove the motherboard.
• The main elements are protected by special steel plates. This is necessary to protect components from electromagnetic radiation. Some plates have heat-conducting paste applied on the reverse side. This is done to protect against overheating.
• Some manufacturers glue the plates with glue. This feature greatly complicates repairs. That's why If you don't need to replace the processor or RAM, then it's better to just leave these plates alone.

Disconnecting the matrix and sensor

The tablet screen consists of a touch part, also called a touchscreen, and a matrix, thanks to which you see the image. These parts have to be changed most often. Since falling on the floor or careless handling causes cracks in these parts. The matrix and touch panel are removed as follows.

• Use a soldering hair dryer to heat the edges of the touchscreen to a temperature of approximately 80–90° to soften the glue.
• After this, slide a plastic card under the touch panel and carefully move it over the gluing areas. Now you can move the touchscreen to the side.
• Next, turn the tablet over and warm up the aluminum case where the matrix is ​​attached.
• Use a plastic spatula to pry up the display and carefully remove it.

Attention! If the tablet's touchscreen or matrix is ​​not damaged, then there is no need to disassemble them.

The fact is that when the touchscreen comes off, it will most likely crack. Plus, the glue that has melted from the temperature will spread across the panel, and you will have to clean it.

We hope that our article will help you when disassembling your tablet. We wish you success and may your tablet never break!
