Material dripping from delayed shut-off
敷形涂层
With electronics required to meet stringent reliability standards such as IPC-CC-830, MIL-I-46058C, and ISO 9001, conformal coating has become a critical process to protect circuit boards from moisture, corrosion, and electrical leakage. To achieve consistent film thickness (typically 25–75 µm) and edge coverage on densely packed components, coating materials must be dispensed with high precision. That’s why a conformal coating system must be tailored to meet application requirements and overcome some process challenges.
Key Challenges
Overspray & material waste
Inconsistent flow rate cause uneven thickness
Air bubbles due to unstable pressure
High Precision Conformal Coating System
NEXGEN’s precision conformal coating system is designed to deliver stable, repeatable film thickness and clean edge definition across complex PCB assemblies. The system integrates servo-controlled metering and high-response suck-back valves to prevent dripping, tailing, and air entrapment during start-stop cycles. With temperature- and pressure-regulated material feed, flow stability and coating uniformity are maintained throughout long production runs, ensuring:
- Consistent coating thickness and smooth surface finish
- Sharp edge control with no tailing or bridging
- Reduced material waste, overspray, and cleaning downtime
