Good evening to the whole community of Steemianos present, once again I apologize for being absent D:, the work has been quite during these days and therefore almost not public. Well, the most important thing is that I'm back to share more knowledge with you without any commitment So stay because we will learn to change an electronic capacitor.

Warning before reading.

I want you to be clear that the next topic is a continuation of my previous post https://steemit.com/cervantes/@fireonxas/educacion-tecnologia-componentes-electronicos-or-que-es-un-condensador-funciones-e-importancia-1, a post where if Remember to talk about the issue of electronic capacitors taking the account the category electrolytic as there are many and was long the subject.

The warning is as follows: In the next post I will give a brief teaching to learn how to change an electronic capacitor, I want to take into account that I am not a professional I only share my knowledge obtained with you, ie, I have Basic knowledge of electronics and I don't want them to come to criticize my pictures taken or the way I express myself in explaining.

Remember that here in Steemit we come to help and contribute to the community (not to speak badly and criticize what others do).Eye, if you can contribute constructive criticism to help me accept it with pleasure.

What will you learn?

.

• Because the capacitors are changed
• How to know if changing a capacitor
• Precautions

 Why do capacitors change?

One of the most frequent causes of change is to correct failures in technology equipment, whether due to load failures, source, ignition, performance.

Basically the technicians make this replacement when a computer does not turn on or has hardware-level failures.  

How to know if changing a capacitor

As you can see in the image below those capacitors are bursting or convex, to know if a filter needs change is simple "If you see that in a power source or board that some is like the photo, you have the fault " and ready. You just have to change them for the same new ones.

Precautions

From here you have to be very careful if they come to try to do what I'm going to teach them, the filters are not toys, they have electricity because they maintain a load to be able to keep a team on.

They must be careful with the capacitors of 400 volts because they give a moderate discharge that does not kill but the experience is not pretty anything XD. They must learn to download them first (that will be taught in another post).

Changing a condenser-Tutorial

The following images are from my audit taken from my cell phone.

1



First of all, we will need an electric cautin or electric welder and tin to be able to follow. I'll use my soldering machine and a little bit of tin.

2

As an example, I'll take a logic card from a DIRECTV L12 Decoder Remove the condenser marked with the red circle (if you wonder why if it's not busted, I'll take it out for this example but remember to replace it only if it's bulged or busted) .

3

They must turn the plate, a safe way to remove the filter without damaging what they call the track (the track is the halo where the two ends of the condenser fit), grip the welder carefully and fill the tin a little.

Then as you can see in the image above, it has two ends, in each one put the welder for 3 to 5 seconds so that a small coating is made. Eye this is not easy because it cost me time to learn because this is done to avoid damaging the track as I said.

4

After performing step 3, turn the plate so that they can grasp the condenser, this time they put the soldering iron on one of the tips so that the tin melts and forcing it out of its place and it is on the outside like the picture above.

Now it's time to put it back.

5

Before putting it, they have to see well what is its correct position, * * The white strip is the negative * * This will also see it in the filter that they buy, that side has to go even so that it does not fence to explode by the bad placement. 

Be aware of the values of the capacitor to be replaced, they have to be exactly the same characteristics.

6

To place it, it is not complicated, they repeat the same thing, they hold the filter with their hand so that it is almost fit in the holes. Then they slowly heat one by one until the capacitor enters completely (I recommend not to make much force).

To finish, fill a little tin to have good contact as the image above. Sorry for the poor quality of the work but this board and previously had taken as an example in my business XD.

Well my friends, this has been all for today, you can really have your doubts but can support a bit of YouTube looking for guides to learn to solder

Thanks for reading and support give me, greetings Steemianos

Also @pharesim a mystery witness XD, but and seen that helps enough users who deserve it.
