How to Detect Small Defects with Computer Vision
Learn how to detect pinholes, bubbles, and subtle, low-contrast defects with computer vision.
Add a real-time inspection layer to every coated board with vision AI for conformal coating inspection. Built for the operations where a skip the size of a fingernail decides whether a board survives a humid summer, a bead of coating creeps into a connector shell and becomes next year's intermittent, or an inspector's eyes adjust to the dark booth differently at hour one and hour seven. Whether you're coating for aerospace, automotive, defense, or industrial electronics, Roboflow inspects the fluorescing coat on every board, after coat and after cure, with a per-board record behind every acceptance.

What is conformal coating inspection with Vision AI?
Conformal coating inspection with vision AI uses computer vision models to inspect coated boards under UV and white light: coverage and skips, bubbles, voids, and pinholes, cracks and dewetting after cure, and coating in keep-out zones like connectors and test points. Models trained on your actual boards, coatings, and fluorescence inspect every board after coat and after cure, with per-board records tied to serial and coating lot that support IPC-A-610 acceptance and customer audits.
Can Vision AI judge coverage reliably in UV fluorescence imagery?
UV inspection is the hard case: fluorescence intensity that varies with coating thickness and material batch, glare off wet coats, board features that shadow the UV source, and edges where thin-but-present coverage looks like a skip. Deep-learning models trained on your actual coatings and imaging setup learn what true coverage, thin edges, and genuine skips each look like under your UV sources, hold that judgment across shifts and batches, and flag borderline regions for review instead of guessing. For coating thickness measurement, dedicated gauges remain the instrument; vision AI verifies coverage, defects, and keep-out compliance.
Does coating inspection support IPC-A-610 and Class 3 programs?
Yes. Roboflow models can run as documented inspection controls against your IPC-A-610 coating acceptance criteria, inside AS9100 (aerospace), IATF 16949 (automotive), and defense electronics programs using IPC-CC-830 qualified materials, with per-board inspection records, imagery, model version history, and training data lineage that support audits and customer source inspection. Roboflow is the inspection engine; your quality team owns the acceptance criteria.
Can it integrate with our coating machines, PLCs, and MES?
Yes. Roboflow Inference exposes a standard API and supports common industrial protocols, so coating inspection events flow into your existing systems: selective coating and dispensing machines, line PLCs from Allen-Bradley and Siemens, MES and ERP platforms like SAP and Oracle, and SCADA and HMI platforms like Ignition and AVEVA, through REST, MQTT, OPC UA, and direct database writes. PLC-level integration routes failed boards to touch-up the moment a defect appears, and every event carries board serial, coating lot, station, and imagery, with a full audit trail behind every board.
