The application of circuit board coating materials (three protective adhesives) in electronic device manufacturing is of great significance
The application of circuit board coating material (Three-proofing adhesive) in electronic device manufacturing is of significant importance as it effectively isolates and protects circuits from erosion caused by chemicals, moisture, pollution, and enhances the reliability of circuit boards. Not using coating materials may lead to the following risks:
1. Copper green phenomenon: Circuit boards exposed to humid environments over time may develop a greenish copper layer due to reaction with moisture. This copper green phenomenon can affect circuit operation, leading to short circuits, open circuits, and other issues.
2. Leakage or short circuit: Without effective sealing protection, moisture, dust, and other pollutants may enter the circuit board, causing local leaks or short circuits and impacting circuit stability.
3. Corrosion and damage: Unprotected circuit boards are vulnerable to contamination, resulting in electronic component damage, pin corrosion, breakage, and affecting the equipment’s performance and longevity.

4. Stability impact: Components and circuits on circuit boards are susceptible to external interference and damage in harsh environments, affecting equipment stability and causing operational abnormalities or failures.
5. Electrical insulation issues: Electronic devices require good electrical insulation performance, and unprotected circuit boards may experience decreased insulation due to moisture, affecting equipment safety.
6. Accelerated aging: Moisture and chemicals can accelerate electronic component aging, reducing the equipment’s lifespan.
Therefore, the application of circuit board coating materials (Three-proofing adhesive) effectively addresses the mentioned issues by safeguarding electronic components from moisture, chemicals, pollution, thus enhancing circuit board reliability and stability. Hence, to ensure normal operation and durability of electronic devices, using coating materials for circuit board protection is essential.
