Why is the circuit board coated with conformal coating?

 Conformal coating, also known as circuit board conformal coating, three anti-adhesive, insulating paint, moisture-proof paint, coating glue, coating glue, moisture-proof oil, generic coating, coating coating, electronic coating materials, etc., the English name is Conformal coating. Circuit board conformable coating is a kind of single-component room temperature curing, heating curing, uv curing transparent or translucent adhesive, 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 assemble all kinds of electronic circuit board, PCB circuit board surface coating, coating function, to provide protection for the circuit board, so that the circuit board to achieve moisture-proof, anti-fouling, anti-salt spray, insulation and other multi-protection, in order to improve product performance, stability, safety and service life.

Why do circuit boards need conformal coating? Yao Neng company concluded that: electronic products often because of some reasons such as short circuit, mainly because of the impact of moisture, moisture, waterproof poor. Moisture is one of the most common and damaging major factors to PCB boards. Excessive moisture can greatly reduce the insulation between conductors, accelerate high-speed decomposition, reduce the Q value, and corrode the conductor. We often see that the metal part of PCB circuit board has a copper green is because there is no coating circuit board conformal coating, metal copper and water vapor, oxygen caused by chemical reaction. Contaminants on printed circuit boards can be just as damaging, eroding conductors and causing irreversible short circuits as moisture can.

The role of leakage prevention is the most basic and important function of conformal coating coating on the circuit board to protect the circuit board. It is a necessary excellent protection product in PCB circuit board assembly. Shenzhen Yaoneng technology co., Ltd. specializes in the production and sales of all kinds of PCB circuit board conformal coating, protective paint, insulating paint, welcome to inquire and sample yaoneng conformal coating related products.
