1.Overview

In traditional manufacturing factories producing precision electroformed stencils, tiny defect quality inspection relies on manual labor. However, manual inspection of small and highly variable defects has problems such as high labor intensity, poor repeatability, high error rate, and unstable quality. Diverse product specifications further increase inspection workload. Manual inspection cannot achieve stable, accurate and efficient detection, leading to unstable yield and reduced productivity.

As a cutting-edge AI technology, AI defect detection has natural advantages in electroformed stencil inspection. It enables non-contact, high-efficiency, cost-effective and high-productivity quality control. Supported by machine vision, inspection efficiency is greatly improved, and standardization difficulties and high false rates are solved.

Based on the DLIA deep learning platform and AI industry models, our AI vision inspection system optimizes defect classification algorithms, supports database and production line upgrades. It achieves pixel-level detection accuracy and millisecond-level speed. The system realizes high-precision, high-efficiency, full-format defect detection for electroformed stencils, reduces labor intensity, improves yield, and enhances enterprise competitiveness.

Standard models are available for photovoltaic, microelectronic, semiconductor BGA stencil, and PCB applications. With fixtures, it can also inspect nickel sheets and other sheet materials. All functions are effectively implemented and optimized.
