PCBA Conformal Coating Service
PCB conformal coating is the process of applying a specialty polymeric film to protect the components in the PCB boards and other electronic parts. The polymeric film forming thickness is considered as per irregular working environmental conditions of the product . PCB conformal coatings helps protect the components against from humidity, heat, debris, aggressive chemicals, fungus, airborne contamination such as dirt and dust conditions.
GWT offers conformal coatings service for low, medium and high volume pcb assembly board. You can apply coatings on partial key components, or complete boards with coatings.Here is an article about How to apply conformal coating to the PCBA board?
Types of PCB Conformal Coating
At GWT, 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 usually one type of solvent dissolvable preformed acrylic polymers. Acrylic coating facilitates easy repair work, as it gets easily dissolved in many organic solvents. The coating offers not only good fungus and humidity resistance, but also offers smooth and crystal clear finish, which makes your pcb assembly board high quality and clean surface.
2.Epoxy: Epoxy resin coating is available as two part compound, and has a good abrasive, chemical, and humidity resistance. The coatings can work in temperatures up to 150°C. Epoxy coating provides a rigid coating on the surface, which offers a superior abrasive and chemical resistance.
3.Silicones: Silicone resin is a soft and flexible coating, which offers excellent corrosion resistance and chemical resistance. The coating has a low dissipation factor, which makes them suitable for high impedance circuitry. Silicone coating can work in the temperature range of 55°C to 200°C. The coating has excellent light transmission properties, which makes it ideal choice for solar applications.
Obviously, PCB conformal coating helps improve pcb assembly board quality and usage life. GWT has provided our customers conformal coating services to kinds of industries and applications. Our skills and experiences ensure you an excellent and reliable coating services. If any demand
For customers who need to protect their equipment from environmental elements such as high humidity, GWT can offer additional protection against these effects on backplanes and partner boards using conformal coating. This coating process applies a special protective surface to the printed circuit board, either manually, or by means of CNC coating machines using a spray coat method.
Depending on the destination of the boards, the different methods protect against moisture, dust or chemicals. They provide powerful protection, ensuring that high demands are met regarding reliable performance, service life and quality – even in scenarios of increased climatic strain.
To prepare the products for their specific environment, we offer a range of coatings, in accordance with IPC-HDBK-830, MIL-I-46058 and IPC-CC-830 standards. Since we also perform some these finishing procedures in-house, we are able to guarantee quality of workmanship. All protective layers are confirmed using optical and mechanical testing.
