PCBA circuit board three-proof paint can effectively achieve insulation, moisture-proof, anti-leakage, anti-vibration, dust-proof, salt spray and other protection effects, enhancing the reliability of the circuit board, increasing its safety factor, and effectively extending its lifespan.
The use of PCBA circuit board paint is widespread in high-tech applications, home appliances, military electronics, aerospace, medical electronics, and other high-end circuit boards. This paint can improve the quality of PCBA boards and significantly reduce the need for rework. The expanding industries such as electric vehicle charging stations and the increasing use of wireless devices have further broadened the application of triple anti-pattern paint. Coating PCBAs with three-proof paint for protection has become a major trend.
The three-proof paint is essential in protecting PCBA boards and related equipment from environmental damage. It enhances the product’s reliability, especially in harsh operating conditions. The coating shields electronic products from external factors like extreme heat, humidity, moisture, and dust. It also guards against internal factors such as corrosion, whisker growth, and in-system short circuits. In essence, the three-proof varnish serves as an insulating layer, ensuring optimal component function and preventing premature PCB failure.
Comparison of Coating Machine and Traditional Coating Process
Traditional coating
(1) Brush coating: prone to air bubbles, waves, and brush stripping;
(2) Row brush coating: slow and lacks accuracy control.
(3) Immersion coating: leads to paint wastage and slow process.
(4) Spray gun: requires fixture protection and cause paint drifting.
Coating machine coating:
(1) Precision paint volume, position, and surface area settings with no need for board wiping post painting.
(2) Enables direct painting of widely spaced plug-in components without fixtures, saving time and labor.
(3) Emission-free operation for clean working environment.
(4) Eliminates need for carbon film covering all substrates using fixtures, reducing collision risks.
(5) Uniform coating thickness with three-proof paint enhances production efficiency, product quality, and minimizes paint wastage.
Automatically coated boards
The PCBA automatic three-proof paint coating machine is an intelligent system designed specifically for three-proof paint application. Equipped with the latest computer control program, it features three-axis linkage and a camera positioning tracking system for precise coating control.
The three-proof paint coating machine, also known as the three-proof paint spraying machine, is specifically designed to control fluid and cover the surface of PCB with a layer of three-proof paint. This can be achieved by dipping, spraying, or spin coating the PCB surface with a photoresist.
An OEM electronic manufacturing factory specializes in PCBA coating machines, primarily used for precise spraying, painting, and dripping of glues, paints, and other liquids onto products. These machines can achieve line, circle, or arc shapes at precise locations.
EMS Electronics offers a full-board tribo coating machine for PCBA, providing a clean, highly efficient, and fully automatic tribo coating process. The precisely controlled spray valve ensures a uniform tribo coating of 0.05mm thickness, significantly improving production efficiency and product quality over manual methods.
In addition, the OEM Electronics Factory specializes in selective tribo coating machines, which provide a clean, highly efficient, and fully automatic selective positioning tribo coating process. This process eliminates the need for overcoating, de-coating, and repair, as the spray valves ensure uniform tribo coating at 0.02mm thickness within the selected area.
There are various names for three-proof paint, including three-proof adhesive, moisture-proof paint, insulating adhesive, protective paint, coating adhesive, water-proof adhesive, and more. These paints can be cured through room temperature curing, heat curing, or light curing methods.
The chemical composition of three-proof paint includes acrylic resin (Acrylic, Type AR), epoxy resin (Epoxy, Type ER), silicone (Silicone, Type SR), polyurethane resin (Urethane, Type UR), and parylene (Parylene, Type XY). Each type offers unique properties for different coating needs.
