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, waterproof, anti-fouling, anti-salt spray, isolation, mildew, insulation and other protection, in order to improve the product performance, stability, safety and service life of the role.
Conformal coating is a flammable class of chemicals, conformal coating material contains some of the human body has a stimulating chemical substances, Yao Neng company engineers to introduce you how to standardize and safe sizing, spraying all kinds of conformal coating.
After purchasing conformal coating products, first check product instructions and precautions, and then prepare the corresponding tools, protective equipment and equipment. The following is recommended by Yao Neng company.
1, if you want to get a thicker coating, it is best to get two layers of coating by spraying and brushing. It is required that the second layer is allowed to be coated after the first layer is completely dried.
2, all coating operation temperature should not be less than 16℃ and relative humidity is not higher than 75% of the climate conditions, PCB board as a composite material easy to absorb moisture. Clean the circuit board first, then dry the circuit board and keep it dry, otherwise the conformal coating will not provide adequate protection. Before painting, it is necessary to remove dust, moisture (moisture) and oil stains from the surface of the object to be coated. If there is moisture, it is recommended to bake the plate at 60°C for 10-15 minutes, and then take it out and spray it after natural cooling in the oven.
3, three anti-paint in the process of construction, should avoid high temperature, heat source and open fire, should have enough ventilation conditions, in order to benefit the solvent volatilization and rapid curing of conformal coating, after curing conformal coating workpiece is basically harmless to human body. Pay attention to safety and protection before spraying. Employees should wear protective masks and gloves.
4. Some products are cured by contact with water in the air. 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 curing of the adhesive layer (but not more than 80℃). The used brush, spray gun, etc. should be cleaned with special cleaning agent in time, in order to prepare for the next use.
5. After pouring out the paint in the bottle, clean the glue at the mouth of the bottle, tighten the cap and seal it in a cool place for storage. When used again, if there is a little crust on the seal, it can be removed without affecting the normal use.
With complete models, stable quality, complete information and timely supply, Yaoneng conformal coating has been purchased by many well-known manufacturers and multinational companies or entered into their global procurement and supply system catalog, and has become a long-term and reliable business partner for the majority of electronic and electrical customers. Welcome to sample and purchase high quality circuit board conformal coating series products.
