Conformal Coating (Printed Circuit Board Protection)


To ensure long-lasting performance & durability of PCBs, applying conformal coating by both automated and manual methods.
Environmental Protection: Shields PCBs from moisture, dust, and chemical exposure in harsh operating environments.
Dual Application Methods: Coating is applied both automatically for efficiency and manually for precision on complex areas.
UV Inspection: Every coated PCB is verified under ultraviolet (UV) light to ensure uniform coverage and quality assurance.
Improved Product Reliability: Prevents corrosion, electrical leakage, and damage – extending the product’s lifespan.
Thermal Preparation (For Heat Dissipation Efficiency)


To ensure effective heat management in electronic assemblies, our thermal preparation process includes:
Solder Paste Application: High-quality solder paste is applied precisely to the heatsink base for optimal thermal contact.
Unit Alignment: Components are carefully positioned and aligned to maintain proper contact between the heatsink and heat-generating components.
Visual Inspection: Each unit undergoes inspection to confirm proper solder coverage and alignment before moving to the next assembly stage.
Enhanced Heat Dissipation: Ensures long-term reliability and thermal stability of the final product.
Testing Procedures
- Functional tests include voltage and resistance checks, ensuring reliability.
- Barcoded traceability allows complete tracking at every production stage.
- Aging and burn-in testing simulate real-world usage for long-term durability.
- In-circuit testing (ICT) is performed for high-volume boards to ensure component placement, polarity, and electrical performance.
- All boards undergo final visual inspection by trained operators to detect any cosmetic or component defects before packaging.
