Hello friends, today we will learn what is smd and where is it used and how is it used, so let us first know what is smd, a surface-mount device or smd is an electronic device For which the components are placed directly on the surface of the PCB. Surface-mount technology, or SMT, is the name of the method used to produce SMD.

smd is such a machine, from which we can remove the component or ic on the mother board. Hot air comes out from smd. Whose temprature and air both we can set, it comes in many companies, everyone’s working and function are different, it comes from 3000 to 15000, as good as the quality of smd The more the control of the temperature will be better in them, if we remove the ic from the expensive smd, then the ic is not damaged and it does not burn the plastic, whereas if we remove the component inside the cheap smd, then motherboard from it Chances of bloating remain and plastic parts also get burnt.

Now we will see that two buttons are placed on top of the smd, one is to control the air and one is to control the temperature. In which condition we should keep how much air and in which condition we should keep how much temperature we will learn.

If we are removing or installing any small component, then we have to keep the air very low and the heat also low and we will use paste to remove the component and if we remove the ic then keep the heat high. And the air also has to be kept more and when we have to take off the shield on someone, then first the motherboard has to be fixed in the PCB stand, after that the air and air have to be kept fast, only then the shield will be able to come off.

There are two types of smd, the first is, inside which the air pump is installed inside the machine, from which the air comes out of the nozzle through the pipe and the second is, inside which the pump is installed inside the handle itself, which We hold it by hand, the pump is installed inside it, the pump is not installed inside the machine, the pump is installed inside the hand hand, air comes out from it and the element is installed there and from that The air heats up.

If you keep the wind strong while taking off the component, then the components fly away, or the accompanying components can also fly, so the wind has to be kept low while taking off the small components. The smd machine should not be kept on for more than 2 minutes, if you use it If you keep it on for a long time, then an element gets burnt inside it.

Now we will learn how smd is used in different ways, assembly is used in different ways in different places like if we will unload any component then its method is different it is not that you have one In this way the assembly has been set up and you can use it to unload all the things in the same way,

In this, whenever you have to take off a component or a different thing, you will have to change its setting, if you do not change the setting, there may be damage in the motherboard, so I will tell you about all the parts one by one. What setting will you do so that there will be no damage inside your motherboard.

First of all we will learn how to take off the charging jack with the help of SMD, to take off the charging jack, first you have to fix it in the motherboard PCB stand, after fixing you have to apply paste on the charging jack. After keeping the temperature of the smd high, high means to keep it between 400 to 500 and the wind has to be kept fast i.e. from 4 to 5 points, now we will see how we have to put the air above the charging jack

Friends, there are many components around the charging jack, which are very important in running the charging, along with the charging jack, most of the mic is also installed, if the assembly air goes on that mic, then it gets damaged. We have also recognized that mic and also have to remove the charging jack. To remove the charging jack, the most important thing is that you have to put the air of the SMD just above the charging jack, the air should not go around, then towards the mic. It should also not be known that the assembly has to be kept absolutely straight, if you close the assembly and apply air, then there are more chances of damage.

What happens many times, that we keep putting air on the charging jack, but the charging jack does not leave the space from there, so the air gets carried away from us, so you have to be patient in this or you increase the heat. Because different charging jacks are installed by different procedures, many charging jacks are installed at very high temperatures, for them you may also have to increase the temperature,

When you apply this air, then only you will know which jack will come down from the high-temperature but first you have to keep the hit medium so that there are no chances of damage if the charging jack is not coming down, then you have to increase the heat and The air has to be put directly over the charging jack, if possible you can put a steel shield over the surrounding components, or cover them with golden tape and secondly when you apply heat, the charging jack with a tweezer Just have to hold it, don’t pull at all,

If you pull the charging jack with the tweezer, the motherboard may get jolted, causing the surrounding components that have just heated up to leave their positions, so when you hit the charging jack, just put the teacher on top of the charging jack. Put it on, not pull, when the charging jack becomes completely hot, it will automatically leave the place and will come out, in this you do not think that the charging jack has to be saved, even if the charging jack gets burnt, there is no problem

Because if the charging jack gets damaged, then a new one is also found, but if the motherboard is hit, then your phone may also be dead, so you have to try to save the motherboard and not the charging jack.

Now we will learn how to remove and put digital mic with the help of smd, most of the people use iron to take off digital mic, and also use iron to put it, by the way no iron to motherboard Doesn’t hurt but when you try to take the mic off the iron, it has prints on the bottom, it’s very likely to come off,

That’s why I would recommend that you use smd but if you do not write the assembly, then you will not be able to remove and put the digital mic from the assembly, so I teach you how to remove and put the digital mic with the help of smd You can, to take off the digital mic, first you have to fix the motherboard inside the PCB stand.

After fixing, paste has to be applied on the mic, a hole is made above the mic, he has to note which side is that hall, after noting you have to keep the hit of SMD medium, and the air also medium Most of it is not to be kept, because the mic is made of steel, it heats up very quickly, it does not require much heat, you have to put air over the mike,

To hold the mic with a tweezer, it will leave its place as soon as the mic gets hot, keep in mind that you must use paste, if you do not use the paste, then the motherboard can also swell below and the heat has to be kept in the media, if possible So we have to keep it less, due to excessive wind, the motherboard swells, and after that the mic can never run in it, it has to be done very carefully, this is what we have learned how to take off now we will learn how to remove the mic How to apply, first we will clean the surface with the help of iron, after cleaning

By applying paste on the digital mic, keep in mind that when we put the shoulder on the digital mic with the iron, the iron is not to touch the mic for a long time, if you do it for a long time, the mic will be damaged, so just You have to do a little touch, so that the shoulder sticks, you have to use a good quality paste there to stick the solder,

What is the use of that folder that when you attach the mic, that shoulder is attached to the shoulder of the surface, so here it is first shouldered, if you don’t shoulder it, then when you attach the mic So the mic does not stick well, even if it sticks, the problem may come again in a few days,

That’s why you have to shoulder the mic first, after shouldering, you have to apply paste on it, after applying the paste, hold the mic in the right direction with a tweezer and after holding the mic again, you have to lift it. Air has to be applied over the surface, keep in mind that I have said that air has to be applied only on it and not on the mic because there is a hole above the mic.

When you put air over it from smd, that air goes inside the mic, which spoils the mic. goes, and on top of the melted shoulder we have to put the mic right away, which we held with the twizzer, as soon as you put the mic you have to put the smd to the side and press and hold the mic for a friend Mike will stick there as soon as you take the teacher away after a friend

After sticking, you have to shake the mic, if the mic is not moving, then our mic is installed, but under the mic, you have to see that the mic is not up from anywhere if by-chance the mic is raised Even if it is left, then you do not have to put air over it from smd, you have to put air around the mic on the motherboard,

Due to which the surface will heat up and the mic can also move from its position and as soon as you move, you have to press the mic again with the help of tweezer, due to which the mic will be properly fixed in its position, and in this procedure the chances of the mic moving is more than 90%. Above are, if you follow this then your mic will feel right in the first time itself which is company fitted, if you put the mic with the help of jumper wire, then the mic goes away but in the future the jumper wire will interact with each other. Shots can also be broken, but if you put the mic without damage to the smd, then its life is very long and no one can judge whether this mic is attached to the market, or the mic from the company This is the best way to apply.
