Yaoneng 163 three-proof paint can be applied to all kinds of assembled PCBA circuit boards to protect the circuit boards from various chemicals, moisture, salt spray corrosion, dust, high and low temperature and other adverse environmental impact, prolong the service life of the equipment and improve the safety and stability of the products.The cured film is compact and bright, with strong adhesion and good aesthetics.At the same time, it has excellent insulation, moistureproof, anti-leakage, shockproof, anti-fouling, dustproof, mildewproof, anti-salt fog, anti-corrosion, corona resistance, anti-oxidation and other characteristics, which can play a significant multi-prevention effect.Mainly used in: hybrid integrated circuit, automobile electronic control board, electronic and electrical circuit board, aviation instrument board, flexible printed circuit, microcomputer control board, semiconductor crystal circuit board, home appliance control system, etc.
1. Clean and dry the circuit board.Before use, clean or clean the circuit board surface of dust, impurities, oil, and remove moisture and moisture.It is recommended to dry the board at 60℃ for 10 to 15 minutes. The circuit board can be taken out and coated with three-proof paint after natural cooling in the oven.
2. Covering and shielding.There are some areas and parts of the circuit board that are not allowed to be covered with triple paint, such as switches, sockets, connectors, radiators, etc.YaoNeng Company suggests that prior to construction can be used tape or the United States tape paste protection.
3, the use of technology.A, spraying process: spraying method in the construction of the preparation of the three anti-paint can be directly added to the spray gun can, the air pressure of the spray gun, spray nozzle and the flow of the paint can be adjusted, after sealing directly for spraying.When the consistency of the three paint is too large, it can be used with YaoNeng 120 type special thinner. After mixing evenly, it should be allowed to stand for 10 minutes until the bubbles are removed before construction. The ratio of the three paint and thinner should not exceed 1.5 times.B, brush coating process: according to the size of the product, choose the wool brush correctly, pour the glue into the container, and then use the brush to stick the appropriate glue to the circuit board for uniform construction, according to the required thickness of the number of brushing.After gluing is completed, the surface can be assembled or packaged after curing. If you need to wait for the first paint to dry before brushing.C, dip coating process: dip coating parts immersed in the glue solution for 2-5 seconds, slowly lift the dip coating parts, tilt, wait for excess glue natural flow off, dip coating parts flat on absorbent paper (small) or support (large), generally within 10 minutes dry, check the surface of the dip coating parts, the area is not painted brush paint.
4. Fix the problem.To repair the finished circuit board, just heat the area with the electric soldering iron to remove the coating, then repair and replace the relevant parts, clean and dry the surface of the board after completion, and then brush the paint to complete.If three anti - paint coating is soft, can be removed with plastic scraper.
5. For more data and information, please consult Shenzhen Yaoneng Company for relevant advice and help.
1, three anti paint in use, the humidity of the construction site can not be greater than 85%, otherwise there will be a slightly white hygroscopic phenomenon.
2, the production process should strengthen ventilation and personal protection work, prohibit open fire, and away from the source of fire and heat source.
3, handling light, packaging cover should be promptly covered, used brush, spray gun should be cleaned in time, in order to be ready for the next time.
4, the test of the parameters of emotion and energy should be carried out at least 24 hours after painting, when the relevant values reach the maximum and stable value.
5, three anti paint will generally have a smell, but the three anti paint is completely cured after no smell.
