Correct practice and specification for conformal coating spraying

Conformal coating, also known as circuit board conformal coating, three anti-glue, insulating paint, coating glue, coating glue, moisture-proof oil, generic film coating, coating coating, electronic coating materials, etc., is an English name of conformal coating.Conformal coating is a single component of room temperature curing, heating curing, UV curing transparent or translucent adhesives, with low viscosity, high transparency, excellent insulation performance, high and low temperature resistance, easy to use and so on.Conformation coating is mainly used in the assembly of all kinds of electronic circuit board surface coating, coating role, to provide protection for the circuit board, so that the circuit board to moisture-proof, anti-fouling, anti-salt spray, insulation and other protection, in order to improve product performance, stability, safety and service life of the role.It can also be used for shallow layer sealing and filling of electronic products.

3 prevent lacquer is to belong to flammable kind of chemical article, contain a few inside to the human body to have the chemical substance that excite sex, yao can company introduces for you how standard and safe spray of all kinds 3 prevent lacquer.

Check the product description and precautions in detail after the purchase of the three anti paint products, and then prepare the corresponding tools, protective articles and equipment.Here's how to do it, according to Yonergy.

1. If you want to get a thicker coating, it is best to get it by spraying two layers of thinner coating. It is required to coat the second layer only after the first layer is completely dried.

2. The temperature of all coating operations shall not be lower than 16℃ and the relative humidity shall not be higher than 75%. As a composite material, PCB board is easy to absorb moisture.Please clean the circuit board first, and then keep the circuit board dry, otherwise the three paint will not be able to provide adequate protection.Before painting, dust, moisture (moisture) and oil should be removed from the surface of the object to be painted. If there is moisture, it is suggested that the drying board should be at 60°C for 10-15 minutes, and then it can be taken out for spraying after natural cooling in the oven.

3, three anti paint in the process of construction, should avoid high temperature and open fire, should have enough ventilation conditions, in order to facilitate the solvent volatilization in the paint and rapid curing, curing after the three anti paint processing workpiece is basically harmless to human body.Pay attention to safety and protection before spraying operation. Employees should wear protective masks and gloves.

4. Some products are cured by contact with water in the air when used.The higher the moisture content in the air, the faster the drying and curing of the adhesive layer;The higher the temperature, the faster the adhesive curing (but not more than 80℃).The used brush, spray gun, etc. should be cleaned with special cleaning agent in time to prepare for the next time.

5. After pouring out the glue in the bottle, the glue at the mouth of the bottle should be wiped clean, the cap should be tightened, and the bottle should be sealed in a cool place for preservation.When used again, if there is a little skin phenomenon at the seal, it can be removed without affecting the normal use.
