What are the main functions of conformal coating?

Release time：2025-12-09

The core function of conformal coating is to provide all-round protection for electronic components and PCBs, ensuring equipment reliability in complex environments. It mainly includes:

Moisture & Mold Resistance：Forms a dense protective film to block moisture and condensation, prevent short circuits and oxidation of metal contacts, and inhibit mold growth, suitable for outdoor and high-humidity environments.

Corrosion Resistance：Protects against industrial atmosphere, salt spray and chemical media (such as oil, electrolyte), preventing solder joints and circuits from corrosion failure.

Insulation Protection：Improves the insulation performance of circuits, prevents electric leakage and arc breakdown between components, especially suitable for high-density integrated electronic equipment.

Physical Damage Resistance：The cured film buffers damage caused by minor vibration and friction, reduces dust adhesion and facilitates equipment maintenance.

What Factors Affect the Light Energy Received by the Conformal Coating ?

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 coating 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 coatings ?

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 using thermal silicone pads?

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
