How do you replace a capacitor? What are the rules? Replacement value within how much can be used?

First of all, use a 30W or 60W pointed soldering iron burn hot enough, and then selected motherboard capacitors, with the tip of the soldering iron to remove the capacitor to be a claw with the melting of the tin swing capacitor at the top of the heated one claw up and the gap between the motherboard to increase the force do not overdo it or else damage to the motherboard, and then another claw hot operation the same, repeated until the capacitor leaves the motherboard.

1: CPU power supply capacitors, this position is generally the original 6.3V-10 electrolytic capacitors, according to the actual voltage of the CPU to replace the CPU core voltage in the last five years of production has not been higher than 2.5V, are in the 1.8V or less, if it is vintage another argument.　Used in the CPU peripheral 6.3V 1500UF-6.3V 3300UF electrolytic replacement can use solid capacitors 4V 1200UF, 4V 1500UF, 2.5V 1500UF, 4V 820UF and 2.5V 820UF can also be competent.　

2: 6.3V1500UF-2200UF (diameter 8MM) electrolytic for 3.3V or 3.3V below the power supply part of the available solid capacitors capacity 330-820UF withstand voltage 4V or more can be. Such as common 4V 560UF.

3: 12V power supply 16V 1000UF-16V 3300UF electrolytic solid capacitors available 16V270UF 16V330UF (12V power supply as a high voltage is not directly supplied to the circuit part of the high-current, so here can be used in the capacity of the smaller).　　

4: The most commonly used 1000UF/6.3, widely distributed with memory slots, AGP slots, PCI slots, this kind of electrolytic for solid: withstand voltage higher than 4V capacity greater than 270UF can be, such as: 4V 560UF, 4V 470UF.

5: Some other commonly used, 470UF/16V electrolytic can be used for solid 180UF/16V. 16v.　　

6: Replacement of small electrolytic capacitors with 10V withstand voltage, please try to use 6.3V or 10V withstand voltage of the solid capacitors, due to the use of 5V power supply chip is not too much and power consumption is not big, the general use of small electrolytic capacitors.
