Why should the PCBA brush 3-resisting lacquer

Electronic circuit board components PCBA (Printed Circuit Board Assembly) as the core of the electronic components, should have good resistance to environmental adaptability and electrical parameters. Moisture + dust + salt spray is an important factor in PCBA failure. Electronic circuit board components coated with three anti (anti-salt spray, anti-heat, anti-mold) paint can withstand the impact of harsh environments on the circuit and components, increase the mechanical strength and reliability, to prevent sudden changes in temperature caused by condensation Wire leakage between the short circuit and even breakdown, for working in high voltage and low pressure conditions of the printed circuit board can improve the wire between the creepage, breakdown phenomenon, thereby enhancing the reliability of the product. hobbystar
