Function and significance of protective coating on circuit board

Conformal coating, also known as circuit board conformal coating, three anti-adhesive, insulating paint, coating adhesive, protective paint, coating adhesive, moisture-proof oil, generic coating, coating coating, electronic coating materials, etc., the English name is Conformal coating. Conformable coating is a kind of single-component transparent or translucent adhesive curing at room temperature, heating curing, uv curing, with low viscosity, high transparency, excellent insulation performance, high and low temperature resistance, easy to use and so on. Conformal coating is mainly applied to the surface covering and coating of all kinds of assembled electronic circuit boards to provide protection for the circuit board, so that the circuit board can achieve moisture-proof, anti-fouling, anti-salt spray, insulation and other multi-protection, so as to improve product performance, stability, safety and service life. It can also be used for shallow encapsulation and protection of electronic products and chips.

Shenzhen Yaoneng Technology Co., Ltd. specializes in the production and sales of various kinds of circuit board conformal coating, and to solve the various problems of conformal coating products and use for customers, to provide a full range of conformal coating solutions.

So why should the circuit board be coated with conformal coating, the role and significance of the circuit board coating conformal coating? We think it is absolutely necessary to coat the circuit board with three anti - paint, which greatly improves the quality of the product.

1. Moisture and water will lead to a decrease in the insulation performance and Q value of the circuit board, which will make the circuit board work in a harsh and harsh environment. Three anti-paint can play a waterproof and moisture-proof role.

2, organic solvents, metal particles, dust, weak acid, alkali and other substances, extremely destructive, will make electronic products failure, circuit corrosion and short circuit, three anti-paint can play the role of acid and alkali, dust, isolation.

3, the long-term corrosion of salt fog, the continuous vibration of the circuit board surface, will make the circuit board by different degrees of damage and damage, three anti-paint can play the role of anti-salt fog, anti-seismic.

4, after coating the circuit board conformation coating also has high and low temperature resistance, aging resistance, flame retardant and other excellent performance.

In summary, the protection of the three anti-paint on the circuit board is quite obvious. In the face of all kinds of adverse environment and various situations
