What are the main functions of conformal paint?

Release time：2025-12-09

The core function of conformal coating is to provide all-round protection for electronic components and PCB boards, ensuring the reliability of equipment in complex environments, including:

Anti-moisture/anti-mold: forms a dense protective film to isolate water vapor and condensation, avoid circuit short circuit and oxidation of metal contacts, inhibit mold growth, and adapt to outdoor and high-humidity scenarios;
Anti-corrosion: resist the erosion of industrial atmosphere, salt spray, chemical media (such as oil pollution, electrolyte), and protect solder joints and lines from corrosion and failure;
Insulation protection: improve circuit insulation performance, prevent leakage and arc breakdown between components, especially suitable for high-density integrated electronic equipment;
Physical damage resistance: The film layer formed after curing can buffer the damage caused by slight vibration and friction, reduce dust adhesion, and facilitate equipment maintenance.

What affects the light energy received by glue?

There are three core factors that affect the reception of light energy by glues, especially light-curable glues:Light source characteristics: the higher the power of the light source, the longer the irradiation time, the stronger the light energy; The wavelength needs to match the glue photosensitiv

Are conformal adhesive and conformal paint the same thing?

The essence of the two in the industry belongs to the same type of electronic protective materials, only the names are different, and the core functions are completely the same - both form a dense protective film on the surface of electronic components and PCB boards to achieve the effect of anti-mo

What are the types of conformal paints?

According to the composition and curing characteristics, conformal paints are mainly divided into four categories: (1) Acrylate type: cost-effective, fast curing, easy to spray and construction, good repairability, suitable for general electronic equipment protection; (2) Silicone type: high and low

What are the precautions for the use of thermally conductive silicone sheets?

The core precautions focus on 5 points: (1) Clean the surface: Before use, use anhydrous ethanol and other cleaning agents to remove oil and dust on the surface of the heat dissipation substrate (chip, heat sink) to avoid impurities affecting the thermal conductivity efficiency; (2) Control the thic
