1. Clean and baked boards, remove moisture and moisture. It is necessary to remove the dust, moisture and oil pollution on the surface of the surface of the device so that it can give full play to its protection effectiveness. Thorough cleaning can ensure that the corrosive residues are completely removed, and the three anti -paint sticks to the surface of the line board well. During the baketing conditions: 60 ° C, 10-20 minutes, it is better to apply it while taking it in the oven.

2. When painting the three -anti -paint method with brushing method, the painting area should be larger than the device to ensure that all coverage devices and piles should be ensured.

3. When brushing the three-proof paint, the circuit board should be placed as flat as possible. There should be no dripping after brushing.

4. Before brushing and spraying three anti -paint, ensure that the diluted three -proof paint is stirred and stirred, and it is placed for 2 hours before brushing or spraying. Use high -quality natural fiber brushes to light and apply it lightly at room temperature. If the mechanical is used, the viscosity of the coating should be measured (with viscosity or flow cup), and the viscosity can be adjusted using the diluent.
