Conins India: Manufacturing Process of PCB Conformal Coating
- Clean the PCB thoroughly to remove dust, oils, and residues.
- Use solvents or cleaning agents to ensure a contaminant-free surface.
- Dry the PCB completely before applying the coating.
- Choose the appropriate conformal coating type (Acrylic, Silicone, Polyurethane, or Epoxy) based on environmental and electrical requirements.
- Ensure the coating material meets industry standards for protection and durability.
- Apply the coating using one of the following methods: spraying, brushing, dipping, or selective coating.
- Maintain a uniform layer thickness, typically between 25 to 75 microns.
- Ensure the coating covers all critical areas without pooling or gaps.
- Allow the coating to cure naturally (air drying) or use heat/UV curing depending on the material.
- Verify curing times to ensure optimal adhesion and protective properties.
- Inspect the coated PCB visually and using UV light to detect coating coverage and defects.
- Perform adhesion and thickness tests to verify coating quality.
- Conduct electrical testing to ensure the coating does not affect PCB functionality.
- Remove any masking materials used during the coating process.
- Clean off any excess coating if necessary.
- Package the PCB properly to protect the conformal coating during storage and shipment.

Features of PCB Conformal Coating in India
Among top PCB Conformal Coating suppliers in chennai India, our all-types-of-PCB-Conformal-Coating are associated with cutting-edge technology formulations like:
- Nano-enhanced Film Technology
Nano-engineered film technology is employed in targeted formulations by us to provide ultra-thin but strongly resistant protective film coatings. It allows space-effective designs and incorporated mechanical strength without additional coating thickness. It is particularly well-suited for tiny electronics and next-generation smart devices where space and efficiency are paramount. - Sprayable UV-curing Solutions
Our fast working conformal coatings which are UV-curable are designed for production lines with the capability to cure instantly without exposure to heat. Not only is this cost-effective in production, but it also protects heat-sensitive components from heat stress. They are perfectly suited for the latest electronics assembly lines that require ultimate throughput with precision and reliability. - Environmentally friendly & RoHS-compliant Chemistry
We are committed to sustainability and make our coatings RoHS compliant to the best possible extent and provide industry-leading protective performance. They contain no toxic solvents or heavy metals and hence are safer for the consumer and the environment too. As the globe is becoming green with production, our materials are future-proof to enable responsible production of electronics. - Flexible, Non-Cracking Compositions
We have developed our coatings with greater flexibility so that they can withstand motion and vibration without delamination or cracking. They are especially tailored for flexible printed circuit boards, wearable electronics, and automotive electronics. Resistance to adhesion as well as protection under dynamic stress is critical in ensuring long-term functionality. - High Transparency Coatings
Our clear formulations are particularly well suited for use in applications where transparency of PCB components such as LEDs or status indicators is a critical concern. These coatings leave no bubbles and create clear, bubble-free finishes with high insulation and water-block properties. This level of protection and visibility is particularly needed in LED lighting, display units, and optical uses.
