The electrical substance of the liquid electrolytic capacitance is liquid electrolyte. The liquid particles are very active at high temperatures, which is pressured inside the capacitor. Its boiling point is not very high. At high temperatures, whether the particles are rising or active than the liquid electrolyte, its boiling point is also as high as 350 degrees Celsius, so it is almost impossible to have the possibility of explosive slurry. Theoretically, solid capacitors are almost impossible to burst.
Solid -state capacitors have better performance than traditional electrolytic capacitors than traditional electrolytic capacitors. According to the test, the equivalent of the equivalent of the equivalent of the solid capacitance during high -frequency operation is extremely small, and the conductivity frequency is good. The characteristics of lower thermal output are the most obvious between 100kHz and 10MHz. The traditional electrolytic capacitance is more likely to be affected by the temperature and humidity of the environment, which is slightly worse in terms of high and low temperature stability. Even if it is 55 degrees to 105 degrees Celsius below zero, the ESR (equivalent series resistance) impedance of solid capacitors can be as low as 0.004 ~ 0.005 ohm, but the electrolytic capacitance will change due to temperature. In terms of capacitor value, liquid capacitors will be lower than the capacitances labeled below 20 degrees Celsius, and the lower the temperature, the more capacitance values \\u200b\\u200bwill decrease, and the power capacity will decrease by about 13%and Celsius in the lower 20 degrees Celsius. The power capacity of minus 55 degrees reached 37%. Of course, this has no impact on ordinary users, but for players who use liquid nitrogen as the ultimate overclocking, solid capacitors can guarantee that the capacitance capacity will not be affected due to the decrease in temperature, which will cause overclocking stability to greatly discount. Because solid capacitors will only decrease less than 5%at minus 55 degrees. There are indeed many advantages in solid -state capacitors, but it is not applicable at any time.
The low -frequency response of solid capacitors is not as good as electrolytic capacitors. In other words, a motherboard is not necessarily the most reasonable to use a full solid capacitance! Whether it is a solid -state capacitor or electrolytic capacitor, their main role is to filter the miscellaneous waves. Therefore The quality of its components can also ensure the stable operation of the motherboard. And this point, electrolytic capacitors can be done!
When the solid capacitance is 105 degrees Celsius, its life and electrolytic capacitors are equally 2000 hours. After the temperature decreases, their life span will increase, but the life of solid capacitors increases greater. Generally, the working temperature of the capacitor is 70 degrees at 70 degrees Or lower, the life of the solid capacitance at this time may reach 23 years, which is almost 6 times that of electrolytic capacitors! But ... will your motherboard continue to use it after 23 years? And this 23 years refers to 24 hours a year 24 hours a day. Putting on, even if the capacitor has such a long life, other components may not be able to stand for 23 years!
Compared with electrolytic capacitors, solid -state capacitors and electrolytic capacitors are far greater than solid capacitors at the same volume and voltage. At present, most of the computer motherboard CPU power supply parts are used in solid capacitors. Less; more due to capacity issues, the frequency of the CPU power supply part has to be increased. In the process of using solid -state capacitors and electrolytic capacitors, the capacity attenuation problems are used. The circuit board with solid capacitors with a slight fluctuation of the capacity will make the power supply ripple, causing the CPU to not work properly. Therefore, theoretically the life span of solid capacitors is very high, but the life of the plate with solid capacitors may not be high.
Repair using solid capacitance computer board: Since the CPU power supply part is often parallel to multiple capacitors, because the solid capacitance does not have deformation, burst pulp, leakage, etc., there is basically no way to determine which one is a failure. Therefore, in maintenance, one of them is often removed (no matter whether good or bad), and a large -capacity capacitor (many times can be used with electrolytic capacitors). This method can generally solve the problem quickly.
Theoretically the life span of solid capacitors is high, but there will still be many failures in the actual use process. The author has encountered the problem of capacitance failure during the maintenance process.
At present, many manufacturers launched the main board with overclocking as the selling point will use solid capacitors. The saying that "the motherboard of solid capacitance is more super" can only be said to be barely correct, and it is not a capacitor who decides to decide overclocking. The design of the line, the development of BIOS, the quality of the CPU itself, and the heat dissipation measures may determine the success or failure of overclocking. Therefore, there is no saying that "replacing the ordinary electrolytic capacitance on the motherboard to a full solid capacitor can improve the overclocking performance of the motherboard." This statement is completely wrong! If the effect of solid capacitance on overclocking, it is because it owns Higher pressure resistance and temperature resistance, so it provides a certain guarantee for the system stability after overclocking.
