Automotive Electronics-Double-Sided, High-Speed Conformal Coating Line

• Full in-line automation: Automatic feeding conveyor → Conformal coating machine → Sealing inspection conveyor → UV curing oven → Automatic flipping machine → Conformal coating machine → Sealing inspection conveyor → UV curing oven → Inspection & collection station
• Double-side conformal coating: Flipping machine enables top & bottom PCB coating, ideal for high-density automotive electronics boards with components on both sides
• High-precision conformal coating: ±0.02mm repeatability via servo + ball screw drive, precisely avoiding connectors, high-voltage terminals and sensitive automotive components
• Sealing inspection integration: Dual sealing detection (after each coating pass) ensures coating integrity, no pinholes or leakage for automotive safety
• UV curing system: Dual UV curing ovens for fast, deep cross-linking, forming a durable coating resistant to high temperature, humidity, vibration, oil corrosion and electromagnetic interference
• Flexible PCB handling: Electric rail width adjustment (50–450mm), fits various automotive PCB sizes (ECU, BMS, infotainment, sensor modules)
• Multi-mode coating: Dot/line/curve/area spraying, eliminates shadow effect for uniform edge coverage on complex automotive PCBs
• SMEMA compatible: Standard SMEMA interface for seamless integration with automotive SMT assembly lines
• 24/7 production stability: Industrial-grade design for mass manufacturing of automotive electronic components

This Automotive Electronics Automatic Conformal Coating Line is a tailor-made solution for automotive manufacturers, addressing the high-reliability and safety demands of ECUs, BMS, infotainment systems, sensor modules and other automotive electronic PCBs.

The entire line integrates automatic feeding, conformal coating, sealing inspection, UV curing, automatic flipping, secondary conformal coating, secondary sealing inspection, secondary UV curing and final inspection/collection modules, realizing a fully 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 protective coating only to the required areas of automotive PCBs, avoiding high-voltage terminals, communication interfaces and sensitive control components—effectively reducing material waste and eliminating the need for manual masking.

The automatic flipping machine is a key highlight for double-side automotive 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 coating fully isolates circuits and prevents short circuits (high temperature, humidity, strong vibration, oil corrosion, electromagnetic interference). Dual UV curing ovens provide fast, deep cross-linking, 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 automotive electronics .

With a standard SMEMA interface, the line can be seamlessly connected to existing automotive SMT production lines. The modular layout (L9960mm × W1350mm) supports flexible expansion, while the flexible programming (manual teaching + mouse-keyboard input) supports quick product changeovers for multi-type automotive 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 strict reliability and safety requirements of global automotive markets.
