Disassembling an old phone

Disassembling an old phone
The major benefit of disassembling old electronics is getting electronic components such as transistors, capacitors, resistors, On/Off switches and even leds.
Let's start
I have two old phones this is one of them:

In the beginning the whole disassembly process was in order to get the phone LCD shown in the above picture, but actually discovered that its wire are damaged near to the input, so nothing to do only continue to get other components;

Plenty of them.
Turning on my iron to start getting resistors at first because they are the easiest components in disassembly process.
After more than 2.5 hours (because I am a beginner to electronic it takes that time from me) of working I finally got these:

And still many components on the board:

If you are thinking about doing the same thing; there are some notes you have to consider:
1-     Almost all electronic components are sensitive to high temperature, so try to do use the iron efficiently, if you expose those components legs to high temperature they will be damaged, actually some electronic components have a printed temperature degree on their back, for example -15 +55 (that means not less than -15 degree nor more +55).
2-     The disassembled devices might have some components not working so after getting them use your multimeter to check if they are working properly.

That’s all for today.
Good luck.
