Integrated Circuits | the correct way to take measurements on ICs

Introducing integrated circuits

As you all know, it is not easy to maintain electronic devices that contain integrated circuits and small electronic components, and the best example of this is a computer that is not easy to maintain, especially if it comes to damage in one of its complex integrated circuits. Even professionals in maintenance but even maintenance experts themselves make mistakes While taking measurements on a certain Essay, of course it is not because of their lack of experience and skills that they make those mistakes, but because of the difficulty of the matter, my loved ones.

In the midst of these difficulties, we must think of an appropriate and practical solution through which we will be able to carry out the task of tracking faults and maintenance in a professional and effective manner, away from repeated errors every time. This post, my dear brothers, which I consider exclusive is a period of research and serious studies that I have done on the best ways to take measurements On complex electronic parts.

Without too long, we go directly to the heart of the matter. The following image is what we will be working on to illustrate the idea

If I ask you what is the correct way to take measurements on the icshown on the picture?

Of course, many will have to take the measurement on the legs of the IC shown in the picture, something intuitive and automatic.

But it is not like that. Why I wonder?

Simply because taking measurements on the legs of the Essie may lead to a short circuit and consequently damage the Essie if the motherboard itself is not, because these legs are close to each other and thus the meeting of the positive side with the negative side of the millimeter is very much possible here, the difficulty of dealing with integrated circuits.

Of course, you will notice arrows pointing to yellow circles. What is the use of these circles I wonder?

Simply dear, in those golden yellow circles the secret lies, so the correct measurement is lifted comfortably away from the fear of the problem of a short circuit. If you notice well, they are far apart from each other compared to the legs of the Essy, then it is the best place to place the ends of the meter device, knowing that those circuits that we are about to talk about are nothing but an extension of the legs of the integrated circuit or the Essy, where if you focus well, you will see a green line connecting each circuit zero with A certain man from the legs of Essy. You will also notice that some of the legs are not connected to these circuits, and this is due to their lack of use on this electronic board that we are working on, and it may be connected to the ground, and since the ground points are many and available on the motherboard, there is no need to increase other extensions to them, in order to avoid congestion on the electronic board in which one millimeter is counted Space is very important. All integrated circuits are the same in this respect.

Without prolonging you, my dear, as long as the idea began to become clear to you, here is this illustration that will bring you closer to understanding the correct way to raise the measurements, which will provide you with complete comfort in maintenance and most importantly, it will save you the money that you were spending to buy a new device for the soap after its original device was destroyed due to The problem of short circuits that we are about to put an end to and which many maintenance technicians suffer from despite their experience and their dealings with various complex integrated circuits.

Measurements are taken between the points marked with green circles, which we said are nothing but an extension of the legs of the Essie and the ground, unlike the places marked in the red circles, so they should be avoided to avoid short circuits.
