What is three anti-paint?

Three-proof paint is a specially formulated coating used to protect circuit boards and related equipment from environmental erosion. Also called PCB electronic circuit board protection oil, moisture-proof paint, three-proof coating, waterproof glue, dust-proof paint, protective paint, three-proof glue, etc. It has good high and low temperature resistance; after curing, it becomes a layer of transparent protective film, which has the properties of insulation, moisture-proof, leakage-proof, shock-proof, dust-proof, anti-corrosion, anti-aging, corona resistance, etc.

The three anti-paint painted on the printed circuit board and components, when affected by the adverse factors of the operating environment, can reduce or eliminate the electronic operation performance decline.

Even if the coating layer of the three anti-paint is very thin, it can withstand mechanical vibration and swing, thermal shock, and high temperature operation. However, the film cannot provide mechanical strength to the parts inserted into the printed circuit board.

The role of electronic cleaning agent

Cleaning agents are widely used in electronic manufacturing processes, and are often used to remove potential flux, solder paste, adhesive residue, and other common contaminants such as dust and debris in the production of PCBs. Cleaning can ensure that the components have a good surface resistance, to prevent leakage caused by the failure of the PCB board to fundamentally extend the service life of the product.
