Custom Surface Spraying Conformal Coating Service for PCB Circuit Board and Electronic Boards Protection

Our custom surface spraying conformal coating service delivers a protective dielectric layer to electronic circuit boards, shielding components and traces from moisture, dust, chemicals, and environmental contaminants. The coating is applied with precision spraying equipment and tailored to the specific layout, component density, and operating conditions of each board.

This service is suitable for prototype runs, small-batch production, and volume manufacturing across industrial, automotive, medical, and consumer electronics applications.

• Custom surface spraying of conformal coating on rigid, flexible, and rigid-flex PCB assemblies
• Selective masking of connectors, test points, and keep-out areas to protect sensitive interfaces
• Compatible with acrylic, silicone, polyurethane, and epoxy-based coating materials
• Uniform film thickness control for consistent dielectric protection across the board
• Support for single-sided and double-sided coating requirements
• Low- and high-volume production runs with repeatable process control

• Extends board service life by resisting humidity, salt spray, and chemical exposure
• Reduces risk of short circuits and corrosion in harsh operating environments
• Improves long-term reliability of electronic assemblies
• Customized coating coverage matched to each board design
• Consistent, repeatable results across production batches

• Industrial control and automation equipment
• Automotive electronics and sensor modules
• Medical and diagnostic devices
• Power supplies and energy management systems
• Consumer electronics and IoT hardware
• Telecommunications and networking boards

Coating material, film thickness, and masking requirements are confirmed per project based on board design and operating environment. Contact our engineering team to discuss your specific application.
