PCB Conformal Coating Service

PCB Conformal Coating Service

The use of PCB conformal coating involves the application of a specialized polymeric film to safeguard circuit board components and other electronic parts. The appropriate thickness of the polymeric film is determined based on the unique working conditions of the product. By using PCB conformal coatings, these components are protected from humidity, heat, debris, aggressive chemicals, fungus, and airborne contaminants such as dirt and dust.

BGPCBA provides conformal coatings services for PCBA boards in low, medium, and high volumes. Coatings can be applied to specific components or the entire board.

Types of PCB Conformal Coating

At BGPCBA, there are various types of PCB conformal coatings. The coatings are applied with the tools of brush and spray, also by dip coating.

1.Acrylic Resin: Acrylic resins are typically preformed solvent-dissolvable polymers of the acrylic type. They allow for effortless repair due to their solubility in various organic solvents. In addition, this coating provides exceptional resistance to fungus and humidity, as well as a pristine and transparent finish, giving your PCBA boards a high-quality and immaculate surface.

2.Epoxy: Epoxy resin coating is offered in a two-part compound and offers excellent resistance to abrasion, chemicals, and humidity. It can withstand temperatures up to 150°C and creates a strong, rigid coating on the surface for optimal protection against abrasion and chemicals.

3.Silicones: Silicone resin is a versatile coating that provides outstanding protection against corrosion and chemicals. Its low dissipation factor is ideal for use in high impedance circuits, and it can perform in a wide temperature range from 55°C to 200°C. The coating also offers exceptional light transmission, making it a top choice for solar applications.

The product of PCB conformal coating is proven to enhance the quality and lifespan of PCBA boards. AtBGPCBA, we are fully equipped to provide conformal coating services to a variety of industries and applications. With our expertise and years of experience, we guarantee exceptional and dependable coating services for all our customers.

Conformal Coating. Bgpcba is your trusted turnkey PCB assembly supplier, providing exceptional conformal coating services to meet all of your board-level requirements.

Painting process has the following four ways

  1. brush coating is common, can produce excellent on a smooth surface coating effect
  2. Spraying coating can be conveniently used repair and small-scale production use, spray gun is suitable for the production Yu Dagui touch, but both spraying means higher requirements for the accuracy of the operation, and may produce shadows (lower components not covered by anti-corrosion paint)
  3. Automatic dip coating — Dip coating can ensure complete coating, and will not cause material waste caused by excessive spraying.
  4. Selective coating – accurate coating and no waste of material, suitable for mass coating, but high requirements for coating equipment. The most suitable for large quantities of film mulch. Use a compiled XY table to reduce masking. Many connectors do not need to be painted when PCB is painted. Adhesive paper is too slow and there is too much residual adhesive when tearing, can consider according to the shape, size, position of the connector, do a combined cover, with the installation hole positioning. Cover areas that need not be painted.

Conformal Coating Application Methods

Choosing the best coating method for your product or application is crucial in PCB coating. Factors such as product volume, application speed, uniformity, and cost effectiveness should all be carefully considered when deciding between conformal coating methods. These methods can be done manually by a skilled technician, such as brush or spray coating, or through an automated process based on your specific needs.

Conformal Coating Solutions

Dip Coating Services

Utilizing the dip conformal coating method, a PCB or other components are fully immersed into the desired coating, providing excellent complete protection for high-speed and high-volume applications. This method is perfect for protecting PCBs.

Brush Coating Services

Conformal coating methods utilizing a brush are a valuable means of manual and precise application to electronic circuits. This technique is suitable for various purposes, such as repair and maintenance, and offers numerous benefits to users.

Vapor Deposition Services

The process of Vapor Deposition utilizes a chemical vacuum polymerization method to uniformly seal PCBs with a Parylene coating. This specialized application can coat LED surfaces with high efficiency, providing exceptional protection against moisture and solvents while also exhibiting low permeability.

Spray Coating Services 

Utilizing either automated equipment or a manual technician, spray conformal coating is applied to selected PCBs. This process ensures a pinhole-free coating and a superior finish compared to brush or dip methods, making it ideal for larger components.

Conformal Coating Inspection and Application Services

Customers can rely on Bgpcba’s expertise to provide thorough testing and laboratory services for all assemblies before coating is applied. Non-compliant assemblies undergo a specialized plasma cleaning process to achieve the required surface cleanliness, resulting in a consistent coating for each circuit board.
