Automated Conformal Coating Inspection for High-Volume Energy PCBAs

What if microscopic flaws in protective layers could cripple your entire energy infrastructure? As demands for reliable electronics surge, even the thinnest film defects in critical assemblies can lead to catastrophic failures. This reality drives our mission to redefine quality assurance for manufacturers operating at scale.

Modern electronics rely on specialized protective layers to withstand harsh environments. These thin films guard against moisture, dust, and chemical exposure – but traditional inspection methods often miss subtle imperfections. For energy sector applications, where PCBAs face extreme conditions, detecting flaws smaller than a human hair becomes non-negotiable.

We combine advanced optical systems with multi-phase illumination to achieve resolutions down to 10 µm. Our technology inspects 120 cm² every second, balancing speed with precision. This approach minimizes human error while validating coating integrity across high-volume production runs. Partnering with industry leaders, we ensure every assembly meets the rigorous standards demanded by precision conformal coating solutions.
