How to change the capacitance of computer board

Computer motherboard for capacitor, has always been the legendary master or Professional computer maintenance division can do things, in my own computer after I went through practice, the whole process of recording down, I hope to help you. This process is the process of changing the capacitor on the motherboard. The article has been fitted with pictures to facilitate everyone to learn.

First ready soldering iron, pliers, flux, suction tin, electric meter, wind gun

Steps/methods are as follows:

1. On the back of the motherboard, apply solder paste on the positive and negative feet of the capacitor.

2. The soldering iron stops on the tin, the suction tin device as far as possible close to. Suck the tin clean.

3. Then add some heat on the solder point, the melting point of the remaining tin, you can pull out the capacitor

4. After taking out the capacitor, if there is tin left in the hole, then use the following figure this method. Don't forget to add the solder paste

5. Unplug the old capacitor and clean the old solder. It is time to install a new capacitor, in the new capacitor need to find out the positive and negative pole of the capacitor. The following figure: capacitance: Can be judged from the foot, long is the positive, short is the negative. Capacitance body, there is a half color paint is the negative. And the motherboard is not uniform, the motherboard capacitor bit has a half is white. But some motherboards are positive, some are negative. It is necessary to refer to the capacitor prior to the replacement of the positive and negative poles. Or look on the motherboard for a marked +/-pole

6. Remove old capacitance and add solder paste on two pin holes

7. Put on the capacitor, in the back of the same solder paste (as shown below), the next is to add solder. Add solder to see their own technology, it is not difficult. But be careful to master the time. In addition, the use of good quality tin wire will be more smoothly completed welding

8. Cut off the extra pins with the pliers.

9. When all the replacements are complete, not yet finished, check the solder joints again and sweep clean. Thoroughly remove the solder paste, if you are ready to buy a special cleaning line and board will be the best collection

10. After the cleaning, the capacitor also changed, I hope to help you.

Simple 10 steps to the capacitor for good, hope to the vast number of computer enthusiasts help. If good, please support me!

Note: In the change of the motherboard capacitor, the novice note is the use of electric iron, you must practice proficiency in the beginning, otherwise easy to the motherboard solder paste.
