Inline automated optical inspection for conformal coating. Under high-brightness UV lighting, the VC Series reliably distinguishes phosphor-bearing coating from bare board — catching missing coating, excess coating, bubbles, splashes, orange peel, and pinholing before boards leave the line. Available for single-sided (VC5000 / VC5100) and double-sided (VC5300) inspection.
Conformal coating protects boards from moisture, dust, and corrosion — but only if it is applied completely and consistently. The VC Series inspects every coated board inline, so coating defects are caught at the source rather than in the field.
High-brightness UV illumination makes phosphor-bearing conformal coating fluoresce, so coated and uncoated areas separate cleanly — the foundation of reliable coating inspection.
Intelligent programming of detection areas across the FOV and of components across the CAD adapts to a wide range of inspection scenarios — from full-board coverage to keep-out zones around connectors.
Supports single-sided automatic inspection (VC5000 / VC5100) and double-sided inspection (VC5300) of conformal coating — one platform scales from simple to complex coating lines.
An optional thickness sensor delivers real-time, high-precision coating-thickness measurement without damaging the coating — verify that every board meets its specified film thickness.
An optional intelligent AI algorithm optimizes detection of bubble defects — one of the hardest coating faults to catch with fixed-rule vision alone.
No coating, insufficient coating, excess coating, bubbles, splashes, orange peel, and pinholing — plus component bump, damage, and missing checks. The defects that matter, all on one pass.
Most conformal coatings contain a phosphor tracer that is nearly invisible under natural light but glows brightly under UV. The VC Series turns that glow into a clear, inspectable signal.
Under natural light, a thin conformal coating is almost impossible to see — bare and coated areas look alike. Under UV, the coating fluoresces, and the same board reveals exactly where coating is present, missing, or out of spec.
The VC Series combines UV fluorescence imaging, flexible polygon programming, optional real-time thickness measurement, and a self-learning AI bubble model — purpose-built for the realities of conformal-coating inspection.
Fast programming generates polygon detection windows that follow the true shape of a coated zone — quickly and accurately identifying irregular coating areas that rectangular windows would miss.
Supports thickness measurement on a variety of coatings without damaging the coating — real-time, high-precision film-thickness data that confirms each board is coated to specification.
Automatic bubble detection built on an AI database trained from a large volume of real production images. The algorithm keeps learning and continuously improves bubble-inspection accuracy over time.
Under UV, coating coverage and its boundaries stand out sharply against the board — making it straightforward to verify clean coating edges, keep-out clearances, and complete coverage of protected areas.
A UV light + RGBW configuration enables combined coating and component inspection, while a UV light + RW option targets coating-only inspection — selected to match your process at point of order.
A 5MP or 12MP industrial camera with a telecentric lens delivers low-distortion, repeatable imaging — resolving fine coating edges and small defects consistently across the field of view.

Conformal coating AOI is the gatekeeper at the end of the coating process — positioned after the UV curing oven so that no miscoated board moves downstream. The series adapts to single- and double-sided coating layouts.
Cleaning → dispensing machine → UV curing oven → Conformal Coating AOI. The VC5100 can also support lower-level reflux inside the machine or bottom-level reflux outside it for fixture-based flows.
Cleaning → dispensing → board-reversing machine → dispensing → UV curing oven → Conformal Coating AOI. Both sides are coated and inspected in a single connected line.
Centralized AOI management enables remote judgement, offline programming, and real-time debugging updates. Rich SPC data charts support line-wide statistics and quality improvement.
Automatic program switching and width adjustment via PCB barcode scanning, with MES command support. Coating, AOI, and dispensing machines exchange data for a true closed-loop feedback system.
Any board that must survive moisture, dust, vibration, or temperature swings depends on complete, consistent coating — verified inline.
