Sinowon: Precision Inspection Solutions for Insulating Ceramic Machined Parts Using Vision Measuring Machine

Abstract: With the rapid growth of electronics, semiconductors, and high-voltage electrical industries, insulating ceramic machined parts are widely used due to their high hardness, heat resistance, and excellent insulation. However, controlling dimensional tolerances of brittle ceramic materials remains a major challenge. This article explores how Sinowon’s Vision Measuring Machine (OMM) and Video Measuring System provide high-precision, non-contact Geometric Dimension Measurement solutions for ceramic parts.

Challenges in Insulating Ceramic Inspection

Insulating ceramics (e.g., alumina, steatite) often serve as insulation bodies in electronic devices. Traditional inspection methods face three key issues:

• Material Fragility: Ceramics are extremely hard but brittle. Contact tools like calipers or micrometers easily cause edge chipping or micro-cracks, leading to scrap.
• Small & Complex Features: As 5G and semiconductor industries evolve, features like hole diameters, edge distances, and step heights on ceramic substrates and insulators become too small for manual measurement.
• Low Efficiency: Manual sampling lacks consistency and cannot meet 100% batch inspection requirements.

Core Advantages of Sinowon’s Vision Measuring Machine (Non-Contact)

Sinowon’s fully automatic Vision Measuring Machines and one-button快速测量 systems use high-precision CCD imaging and advanced algorithms to automate Geometric Dimension Measurement.

• Zero Stress (Non-Contact): By capturing contours through lighting, the Video Measuring System never touches the ceramic surface, completely preventing physical damage.
• Micron-Level Accuracy: Equipped with imported high-precision guides and telecentric optics, repeatability reaches micron levels, meeting tight ceramic tolerances.
• No Human Error: Automatic edge detection eliminates parallax and reading errors, ideal for sharp-edged ceramic parts.

Specific Measurement Applications for Ceramic Parts

Sinowon’s Vision Measuring Machine offers comprehensive Geometric Dimension Measurement for insulating ceramics:

1. 2D Geometric Dimension Measurement (OMM – Optical Measurement Machine)

The most frequent application for ceramic inspection.

• Linear Dimensions: Length, width, thickness, hole diameter (round/square), center distance, edge distance.
• Arcs & Angles: Measure R-angle radius, acute/obtuse angles on complex ceramic structural parts to verify mold accuracy.

2. Flatness & Warpage Measurement for Ceramic Substrates

For DBC/AMB ceramic substrates or thick-film circuit boards, flatness directly affects bonding and printing quality.

Flatness Analysis: Sinowon’s system uses laser-assisted focusing or 3D scanning to calculate surface flatness error, generating height difference maps to ensure substrates are warp-free.

3. Complex Contour Comparison

For irregular ceramic insulators (e.g., high-voltage relay housings, fuse ceramic tubes):

Overlay Comparison: Overlay the actual part image with CAD drawing. Instantly visualize oversized or undersized areas for fast mold adjustment.

4. Micro Features & High-Volume Measurement

• Small Defect Detection: Capture tiny edge chipping or chamfer widths using high-magnification lenses.
• Batch Measurement: One-button fast measuring models support large FOV, measuring multiple small ceramic washers simultaneously at high speed.

Production Quality Issues Solved

By adopting Sinowon’s Vision Measuring Machine, ceramic machining companies effectively:

• Eliminate False Scrap: Non-contact measurement solves the problem of “chipping during inspection,” reducing production loss.
• Improve Yield Rate: Strict Geometric Dimension Measurement ensures assembly compatibility for downstream electronics customers, preventing field failures.
• Build Data Traceability: Software supports SPC analysis and auto-report generation. Managers monitor real-time batch fluctuations, supporting process improvement.
