When brushing, the circuit board should be laid flat as much as possible, and there should be no dripping after brushing. The brushing should be flat, and the price of printed circuit board assembly and raw material prices have skyrocketed.

The method of brushing is not used for the time being, but it is still possible to brush other components. It is necessary to apply 150 external brushes first. During construction, use a small shovel or brush to evenly apply a layer of flexible and gauze to the surface of the components to be coated. After polishing, do not apply to the uneven surface of the components.
Good materials should be brushed according to the movable parts, and the direction of the coating points should be basically consistent. Otherwise, it can be a replica of ordinary coatings or several basic directions of ordinary spray paint that need to be reused.
As for the 15/20 low adhesive epoxy resin, it only takes two coats to achieve perfect low-temperature performance. The lower the temperature, the better its performance.
Operating environment: The nozzle should not be exposed to high temperature for a long time, as it may cause a layer of mica film to adhere to the surface.
After the process is mature, epoxy resin will have a low adhesive value that cures at room temperature, and is commonly used for packaging electronic devices, such as double-sided circuit boards.
Engineering experiments use epoxy resin encapsulation, with epoxy resin mesh as a composite medium, which has good sealing performance and can effectively isolate humid and destructive substances from the outside. At the same time, it has good thermal conductivity, making it the most suitable insulation encapsulation product for various electrical industry encapsulation.
It can be heated indoors, fixed at room temperature, and after sealing, it has good adhesive properties. Epoxy resin is a bonding and sealing material used for sealing electronic components such as automotive relays, electronic modules, and integrated circuits. Used for the bonding and fixation of LED encapsulation, power encapsulation, LED modules, etc. During normal operation of automotive circuits, it is allowed to pass certifications such as high temperature and humidity at 200 ° C, 24-hour aging resistance, moisture resistance, mold resistance, and environmental protection.
