Instrument Industry-Accurate Readings, Durable Protection

• Full in-line automation: Automatic lifter → Automatic feeding conveyor → Conformal coating machine → Sealing inspection conveyor → IR curing oven → Automatic flipping machine → Conformal coating machine → Sealing inspection conveyor → IR curing oven → Automatic lifter
• Lower rotary track design: Dual-layer track (upper production, lower return) optimizes workshop space and material flow efficiency
• Double-side conformal coating: Flipping machine enables top & bottom PCB coating, ideal for high-density instrument boards with components on both sides
• High-precision conformal coating: ±0.02mm repeatability via servo + ball screw drive, precisely avoiding connectors, sensor interfaces and sensitive instrument components
• Sealing inspection integration: Dual sealing detection (after each coating pass) ensures coating integrity, no pinholes or leakage for instrument reliability
• IR curing system: Dual infrared curing ovens for uniform, stable curing, forming a durable three-proof coating resistant to high temperature, humidity, dust and chemical corrosion
• Flexible PCB handling: Electric rail width adjustment (50–450mm), fits various instrument PCB sizes (process instruments, analytical instruments, smart meters)
• Multi-mode coating: Dot/line/curve/area spraying, eliminates shadow effect for uniform edge coverage on complex instrument PCBs
• SMEMA compatible: Standard SMEMA interface for seamless integration with SMT assembly lines
• 24/7 production stability: Industrial-grade design for mass manufacturing of instrument components

This Instrument Industry Automatic Conformal Coating Line is a tailor-made solution for instrument manufacturers, addressing the high-precision and reliability demands of process instruments, analytical instruments, smart meters and other industrial instrument PCBs.

The entire line integrates automatic lifting, feeding, conformal coating, sealing inspection, infrared curing, automatic flipping, secondary conformal coating, secondary sealing inspection, secondary infrared curing and unloading modules, with a lower rotary track for material return, realizing a closed-loop automated double-side coating production flow. The core conformal coating machine adopts a high-precision servo + ball screw drive system with ±0.02mm repeatability, which accurately applies three-proof protective coating only to the required areas of instrument PCBs, avoiding sensor interfaces, communication ports and sensitive electronic components—effectively reducing material waste and eliminating the need for manual masking.

The automatic flipping machine is a key highlight for double-side instrument PCBs: it safely flips the PCB 180° after the first coating and curing pass, enabling precise coating of the bottom side components. Dual sealing inspection conveyors detect coating integrity, pinholes and leakage after each coating pass, ensuring the adhesive fully isolates circuits and prevents short circuits or electrical corrosion in harsh industrial environments (high temperature, humidity, dust, chemical corrosion). Dual infrared curing ovens provide uniform and stable heating, quickly solidifying the coating to form a dense protective layer that withstands long-term thermal stress, mechanical vibration and extreme environmental corrosion, extending the service life of instruments and meeting IPC-CC-830B and other international instrument reliability standards.

With a standard SMEMA interface, the line can be seamlessly connected to existing SMT production lines. The modular layout (L12740mm × W1350mm) and lower rotary track design optimize workshop space utilization, while the flexible programming (manual teaching + mouse-keyboard input) supports quick product changeovers for multi-type instrument production. This solution not only improves production efficiency by over 300% compared with manual coating, but also reduces the defective rate to below 0.1%, helping manufacturers meet the precision and reliability requirements of global instrument markets.
