Three anti-paint function on PCBA circuit board

Under real conditions, such as chemical, vibration, high dust, salt spray, humidity and high temperature, PCBA circuit boards may have corrosion, softening, deformation, mildew and other problems, resulting in PCBA circuit board circuit failure. PCBA circuit boards produced by Changsen are basically made of three-proof paint, what function does the three-proof paint have? Here is a brief introduction:

The three-proof paint can prevent PCBA leakage, so it allows higher power and closer printed board spacing. Thereby, the purpose of miniaturization of components can be met.

   The three-proof paint is coated on the surface of the PCBA circuit board to form a three-proof protective film (three-proof refers to moisture-proof, salt-fog-proof, and mildew-proof). Under conditions such as chemical substances (for example: fuel, coolant, etc.), vibration, humidity, salt spray, humidity and high temperature, the circuit board that is not used with the three-proof paint may be corroded, mold growth and short circuit, etc., leading to the circuit In the event of failure, the use of three-proof paint can protect the circuit from damage, thereby improving the reliability of the circuit board, increasing its safety factor, and ensuring its service life.

   Three anti-paint is a kind of specially formulated paint, used to protect circuit boards and related equipment from environmental erosion. The three-proof paint has good resistance to high and low temperature; it forms a transparent protective film after curing, which has excellent insulation, moisture resistance, leakage resistance, shock resistance, dust resistance, corrosion resistance, aging resistance, corona resistance and other properties.
