Nowadays, there is a great demand for CPU coated with silica gel and silicone coated graphics cards. Many users ask how silica gel coated works well. Affected by this, the demand for suitable silicone rubber valves and special storage silicone pressure barrels and other accessories is on the rise, so this paper will briefly introduce how to control the effect of silicone gel and its application in coating to achieve the application effect.

Fluid thermal conductive silica gel
 
Most of the fluid silica gels have poor fluidity and strong adhesion, including common types such as organosilicon or coated silica gel. Therefore, the storage in the pressure bucket of silica gel should be supplied through the bottom outlet mode. There are also differences in the selection of rubber valves. Based on this, several methods of coating silica gel are briefly introduced. Production line control implements alternative methods for industries such as CPU-coated silicone or silicone-coated graphics cards.
 
Silica Gel Pressure Barrel for Storage
 
Summary of Silica Gel Coating Method

Central single point coating
 
The application of common single point central coating mode is relatively simple. When applying silicone gel to CPU, a proper amount of silicone gel is extruded at the central position of semi-finished CPU and then the radiator is pressed on CPU to bond. It is necessary to choose whether to coat silicone gel or to use silicone gel, and this process requires silicone pressure barrel to supply materials steadily and continuously. It is necessary to set and adjust the pressure and parameters of the pressure barrel before putting it into application.
 
Five-Point Adhesive
 
Some users asked how to coat the silica gel of the production line to achieve uniform coating distribution. Therefore, the small edition recommended the use of five-point pattern coating material around the layout, that is, the right amount of silicone gel or coated silica gel at the four corners of CPU or graphics card and the central point, which is more suitable for the industry application of silicone-coated graphics card. Compared with CPU coated silica gel, the production of graphics cards requires uniform distribution and strong bonding. Therefore, this method is more suitable for coating silica gel. It is necessary to select suitable dispensing valves and pay attention to adjusting the pressure of silica gel pressure barrel. This mode has a high filling thickness, so this method is more suitable for the application of graphics cards.

In fact, the method of how to coat silica gel is one of them. The control and difference of this method will be decided by the adjustment and selection of accessories, including the application of silica gel-coated graphics card or CPU-coated silica gel, which can control the distribution of silica gel. It is necessary to adjust the corresponding effect before operation. With parameters, avoid high error caused by repeated adjustment.
