Ceramic Printed Film Visual Inspection Machine | Precisely Detecting Micron-Level Defects

2026-01-27

In the manufacturing process of MLCCs (Multi-Layer Ceramic Capacitors), the integrity of electrode patterns directly determines the electrical performance and reliability of the products. Film appearance defects during the electrode printing stage after tape casting are often a key factor affecting production yield. How to achieve automated inspection with high precision, high speed and traceability? Hitech Precision Industry proudly launches the Offline Ceramic Printed Appearance Visual Inspection Machine, driven by AI + optical technology, setting a new standard for MLCC inspection!

 

01 Product Overview

1.Specially Designed for the Front-End Process of MLCC

High-Resolution Industrial Camera: The “Eye” of the Inspection System
Serving as the visual core of the system, the camera must deliver high definition and high compatibility, ensuring the capture of micron-level defects on printed surfaces.
High-Precision Inspection Platform：Equipped with a 16K line-scan camera, the platform adopts an image stitching technique to achieve a single-pixel precision as low as 4μm. It clearly presents tiny defects and prevents missed detections caused by insufficient resolution.
To meet the multi-specification adaptation requirements for printed films with different patterns, the operation interface is designed with the priorities of reducing complexity and enhancing intuitiveness. Visualized parameters make the adaptation status clear at a glance, ensuring that operators can quickly switch the inspection settings for films with different patterns and models without professional expertise.
With robust AI image recognition algorithms and optical inspection capabilities, the equipment can accurately identify and classify various types of defects on printed films. It achieves a comprehensive upgrade from manual visual inspection to intelligent judgment, helping customers improve product yield, reduce labor costs, and ensure product consistency.

02 Core Advantages

  1. Ultra‑High Resolution Imaging System：The camera features a resolution of 16384, with a single‑pixel accuracy of 0.004 mm (4 μm). It can clearly capture micron‑level defects, ensuring zero missed detection.
  2. Efficient and Stable Inspection Performance：The inspection speed is ≤60 seconds per piece (standard model). It supports flexible switching between offline and standalone modes, and is compatible with various product models to meet diverse production requirements.
  3. AI Intelligent Judgment + Positioning and Traceability：The system adopts dual algorithms: traditional image processing and AI deep learning. It can automatically classify defect types and mark their coordinate positions. The inspection data can be exported to the MES system, realizing full‑process quality traceability.
The Haitai Precision Ceramic Printed Film Visual Inspection Machine has been extended to an online inspection system. Essentially, it upgrades the “offline sampling and static inspection” mode to an online inspection solution featuring production line linkage and real-time detection, achieving online micron-level inspection accuracy.
 
Tailored precisely for this purpose, it safeguards the perfection of every film with the eyes of technology; and propels the MLCC industry into a new phase of high-quality development through an intelligent brain.
