Select the appropriate thermal grease and apply the correct method. Read the manual carefully in advance to understand the performance and usage time. When the expiration date is approaching, find a suitable opportunity to replace it. Only in this way can the thermal grease exert good performance to ensure the normal operation of the machine.
Some people don't know why to use thermal paste? Use it in the gap between the heat sink and the CPU to fill and improve heat dissipation. With the help of this adhesive, components can be tightly bonded together for better thermal conductivity.
The heat dissipation performance of air, namely the thermal conductivity efficiency of 0.024 W/m. K, is very low, and the heat dissipation effect is very poor. If high-power components only rely on air for heat dissipation, the heat cannot be conducted in time, and it is easy to form local high temperatures, which may damage the components and components, thus affecting the reliability and normal working cycle of the system. Therefore, it is very important to choose the power supply potting glue carefully.
The appearance of bubbles on the surface of the potting compound, the wrinkling of the surface, and the oil on the surface are all appearance problems. So why do these appearance problems occur in the potting compound, and how to eliminate the bubbles?
The influencing factors of the sedimentation phenomenon of the potting glue are mainly reflected in the uneven production and stirring, the improper storage of the powder, the serious moisture absorption, the high storage environment temperature, and the poor compatibility of the oil and powder.
In the process of potting adhesive application, most users have a defoaming process. The purpose is to ensure that there are no air bubbles and pores inside and on the surface of the colloid after the product is cured, so as not to affect the performance of the product. You may think that defoaming is a very simple operation. Open the vacuum box and pump it.
