What are the protective effects of three anti-paints on PCBA processing circuit boards? At present, the country has increasingly stringent requirements for environmental protection and is making greater efforts in link governance. This presents both a challenge and an opportunity for PCB factories. If PCB factories commit to addressing environmental pollution, FPC flexible circuit board products can take the lead in the market, providing PCB factories with opportunities for further development. The Internet era has disrupted traditional marketing models, consolidating a wealth of resources through online platforms, which has accelerated the development of FPC flexible circuit boards. However, as this development progresses, environmental issues will continue to arise in PCB factories. Fortunately, with advancements in the Internet, environmental protection and informatization have also progressed significantly. Environmental information data centers and green electronic procurement are gradually being integrated into actual production and operations. Three-proof paint, also known as PCBA processing electronic circuit board moisture-proof oil, includes moisture-proof coatings, waterproof glues, anti-corrosion paints, salt spray paints, dust-proof paints, and protective coatings. PCBA circuit boards treated with three-proof paint exhibit “three-proof” performance: waterproof, moisture-proof, and salt-fog resistant, along with heat and cold shock resistance, aging resistance, radiation resistance, salt spray resistance, ozone corrosion resistance, vibration resistance, and strong adhesion. These characteristics are crucial for enhancing reliability.

Moisture is the most common and destructive factor affecting PCB circuit boards. Excessive moisture significantly reduces the insulation resistance between conductors, accelerates high-speed decomposition, diminishes the Q value, and leads to conductor corrosion. It is not uncommon to observe patina on the metal components of PCB circuit boards.
