Core Service Introduction
Our professional Conformal Coating service provides reliable environmental protection for printed circuit board assemblies. It extends product lifespan and enhances reliability in harsh operating conditions. Automated precision coating equipment is used to apply a uniform, thin protective polymer film to PCBA, safeguarding the circuit board and components from moisture, dust, chemicals, corrosion, vibration, and thermal shock.
Core Capabilities
Diverse Coating Material Options: We offer a full range of conformal coating materials to match application requirements, including acrylic resins, silicone resins, and urethane resins. All materials are fully compliant with RoHS and REACH environmental regulations.
Customized Solutions: Our engineering team provides professional coating scheme optimization based on product application environment, including coating material selection, coating area definition, and thickness specification.
Technical Advantages
Precision Coating Technologies: We use multiple application methods to match design needs, including automated selective coating, automated spray coating, and manual brushing. Selective coating equipment precisely avoids connectors, switches, test points, and other non-coating areas, ensuring no impact on product functionality and reworkability.
Process Integration: Our conformal coating service is fully integrated into PCBA production workflow. It is applied after final assembly and testing, with UV curing or thermal curing systems to ensure fast, complete curing of the coating.
Quality Assurance
Rigorous Process Validation: Before mass production, we perform a first article coating validation, verifying coating thickness, coverage uniformity, edge definition, and curing quality through high-magnification visual inspection and thickness measurement.
Full Inspection: Every coated PCBA undergoes 100% visual inspection to verify coverage integrity, no missing coating, no overflow to non-coating areas, and no defects such as bubbles, cracks, or unevenness.
Process Control
Complete production and inspection records are retained for every batch. The conformal coating process fully complies with IPC standards. Materials and processes meet ISO9001, IATF16949, and ISO13485 quality system requirements.
Typical Application Fields
Our Conformal Coating services are ideal for PCBA applications in industrial control equipment operating in humid and dusty workshops, automotive electronics exposed to temperature fluctuations and vibration, outdoor 5G communication equipment, medical devices requiring disinfection and corrosion resistance, marine electronics, renewable energy controllers, and consumer electronics requiring moisture and sweat protection.
