To protect circuit boards and related equipment from the erosion of a bad environment, to improve and extend their service life, ensure the safety and reliability. Military protective liquid formulation is applied to the circuit board appearance, forming a layer of light and flexible only 25-50 microns thick film. It can contain chemicals such as: the case (such as fuel, cooling, etc.), vibration, moisture, salt spray, humidity and high temperature protection circuit from damage. PCB may be corroded under these conditions, mold growth and produce a short circuit, resulting in an unutilized military protective liquid formulations of circuit failure. This metal film protective agent benefits our military protective liquid formulation applications are: Military protective film protective liquid formulation can effectively isolate and protect the circuit from chemicals, moisture, and other contaminants erosion, thereby increasing the circuit board reliability, increase the safety factor, and to ensure its service life. Military protective liquid formulation prevents leakage, thus allowing for higher power and more recent PCB spacing. Which can meet the miniaturization purpose element. Whether transparent or colored military protective liquid formulation can improve the appearance of the printed circuit board, and the latter by the cover member and the design layout also ensures a higher degree of confidentiality. 3.2 Antioxidant paste solder imported imported antioxidant paste, green oil circuit board having oxygen barrier. From the plug-in, welding, cleaning, drying to "three" liquid spray, are specialized equipment to complete the whole process, protection is valid for 10 years.
