Anti-corrosion paint is a kind of special formula of paint, used to protect circuit board and related equipment from bad border of erosion, so as to improve and extend their service life, ensure use of safety and reliability. Anti-corrosion paint coated in PCB appearance, form a layer of both light and flexible only 25-50 microns thick film. It can be in such as containing chemicals (e.g., fuel, cooling

Agents), vibration, moisture, salt spray, damp and hot circumstance protection circuit from damage. Under these conditions PCB can corrode, mould to grow and produce a short circuit and trigger unused anti-corrosion paint circuit fault occurs.

Application of anti-corrosion paint benefits

Three proofing lacquer form protective film can effectively isolate and can protect circuit from chemicals, damp, and other contaminants erosion, so as to improve the reliability of the PCB, increase its safety coefficient, and ensure its service life. Because anti-corrosion paint can prevent leakage, thereby allowing the higher power and more recent PCB spacing. Thus, can satisfy the purpose of miniaturization components. No matter the transparent or colored three proofing QiJunKe improve the appearance of printed circuit board, while the latter through cover components and design layouts also can ensure the higher degree of confidentiality.

Typical application

Initial anti-corrosion paint applies only to high-tech fields of printed circuit board. Now consumers pay more and more attention to product quality and reliability, and electronic devices were also more widely used in daily life, the use of anti-corrosion paint allows manufacturers to improve product quality, reduce the penetration year-period warranty fault expenses.

Typical USES include the following scale

Civil and commercial application

Anti-corrosion paint for household appliances in the electronic circuits provide protection, make they can resist:

Water and detergent (such as: do laundry machinery and dishwasher)

Humidity (such as microwave)

Chemicals (such as: washing machine/dryer)

Office and home of pests (such as computer)

External adverse environment (e.g., anti-theft alarm device)

Automobile industry

Automobile industry requirements anti-corrosion paint protection circuit from several situations, such as: the harm of gasoline evaporation content, salt fog/brake fluid, etc. The application of electronic systems in automobile continuously growing rapidly, so using three proofing lacquer has become ensure automotive electronics achieve long-term reliability basic requirements.

Anti-corrosion paint application in the following aspects:

J machine under the hood (e.g. engine management system)

Passenger compartment (plus j: car's computer control system)

aerospace

Aviation, space environment of electronic equipment, strict in that environment, compression, decompression fast, the impact on a circuit's electrical performance, and therefore must be used extensively anti-corrosion paint. Anti-corrosion paint can be applied to the following compression, decompression region:

Decompression.

(such as: flight line control system)

Machine storehouse.

Air conditioning system) (such as:

.

sailing

Whether the fresh water and salt water both will have Marine equipment of electrical lines harm. Use anti-corrosion paint can maximize the protection on the surface, but for equipment in underwater equipment, immersion use resin protected almost is indispensable. Typical applications include

J navigation system

J radar control system

Medical/industrial

Anti-corrosion paint protection equipment from external bad environmental erode. The application area is very promising, mainly including:

Tools -, prevent rust, be helpful for storage

Agricultural machinery. - prevent fertilizers and in waste pollution for

Pacemakers ensure continuing stability
