Automated Conformal Coating

1

Protecting Electronics in Harsh Environments

Conformal coating is a specialized process where a thin polymeric film is applied to a Printed Circuit Board Assembly (PCBA). This film “conforms” to the board’s components and topology, providing a high-performance protective barrier against environmental stressors.

Technical Advantages

Environmental Barrier: Provides superior protection against moisture, dust, chemicals, and salt spray, which is critical for Automotive Exterior and Smart Infrastructure applications.
Dielectric Integrity: Prevents arcing and short circuits in high-density electronic layouts by providing an additional layer of insulation.
Tin Whisker Mitigation: Helps prevent the growth of tin whiskers, ensuring long-term reliability in safety-critical systems.

SGA’s Automotive-Grade Process

Selective Coating Mastery: We utilize state-of-the-art automated selective coating systems. This allows for high-speed application with micron-level precision, ensuring that “keep-out zones” (like connectors) remain uncoated.
Integrated UV-Inspection: Every coated board undergoes automated UV inspection to verify 100% coverage and film thickness, meeting the stringent IATF 16949 quality requirements.
