Sinowon: Comprehensive Application of Vision Measuring Machine in Precision Measurement of Insulating Ceramic Machined Parts

Introduction

With the rapid development of electronics, semiconductor manufacturing, and high-voltage power transmission industries, insulating ceramic machined parts are widely used in precision tooling and structural components due to their excellent insulation, high-temperature resistance, and high hardness. However, the brittleness and surface quality of ceramic materials directly affect their assembly performance and service life.

Sinowon has developed a comprehensive dimensional control solution based on high-precision Vision Measuring Machines specifically tailored for insulating ceramic parts. We not only solve the pain point of "inaccurate measurement" but also help enterprises achieve digital upgrades in Geometric Dimension Measurement through our advanced Video measuring system.

Key Measurement Challenges in Insulating Ceramic Machined Parts

• Thin and Brittle Characteristics: Many ceramic parts (e.g., ceramic substrates, sealing rings) are extremely fragile and thin. Traditional contact measurement methods easily cause edge chipping or deformation.
• Difficult Focusing on Reflective Surfaces: Ground or polished ceramic surfaces are often reflective, making it difficult for conventional inspection equipment to capture edges quickly.
• Strict Form and Position Tolerance Requirements: In multi-layer packaging or mechanical assemblies, the accuracy of Geometric Dimension Measurement directly determines the product yield.

Core Measurement Capabilities of Sinowon Vision Measuring Machines

Sinowon offers both fully automatic and manual high-precision Vision Measuring Machines, featuring high-performance optical systems and advanced imaging algorithms. They cover the following four major measurement dimensions:

1. Basic Geometric Dimension Measurement

This is the most fundamental and frequent inspection requirement. Our machine precisely captures the edge contours of ceramic parts, automatically recognizing and measuring length, width, height, inner diameter, outer diameter, roundness, and angles.

Problems Solved:
Replaces manual caliper readings, eliminates human error, and quickly determines whether incoming wire diameters and hole diameters are within tolerance. Especially suitable for batch sampling of ceramic parts like mobile phone back covers or electronic cigarette ceramic housings.

2. OMM (Optical Measuring Machine) & Micro-Hole Measurement

For micro-holes, slots, and complex irregular structures commonly found in ceramic parts, Sinowon employs high-magnification optical lenses to clearly image and measure feature sizes at millimeter or even micron levels.

Problems Solved:
Addresses the difficulty of "seeing and measuring" small dimensions. For example, micro gears in ceramic injection molding (CIM) or lead holes in relay ceramic housings – using OMM, high-precision data can be obtained without contact.

3. Flatness & Warpage Measurement

Flatness is a critical indicator of insulating ceramic board quality. Sinowon’s Vision Measuring Machine not only provides 2D measurement but also integrates laser or probe modules to achieve high-speed 3D flatness scanning.

Solutions:

• Multi-point scanning: Selects multiple points on the surface of a thin ceramic sheet to quickly calculate overall flatness error.
• Warpage analysis: For large-sized ceramic covers, checks for deformation after sintering.

Problems Solved:
Prevents soldering voids or cracks in SMT assembly caused by poor ceramic flatness. This solution has been successfully applied in ceramic substrate manufacturing, effectively improving product assembly yield.

4. Form & Position Tolerance Measurement

For insulating ceramic parts requiring high-precision assembly, single dimensional conformity doesn’t guarantee assembly quality. Our machine features powerful Geometric Dimension Measurement software algorithms capable of calculating complex form and position tolerances.

Measurable Items:

• Perpendicularity & Parallelism: Ensures the sidewalls of ceramic brackets are perpendicular to the bottom surface.
• Position Tolerance: Measures the actual positional offset of multiple holes on a ceramic cover relative to a datum.
• Symmetry: Used to inspect the central symmetry of ceramic sliders or guide rails.

Problems Solved:
Ensures mold machining precision, enabling complex ceramic components to achieve high interchangeability in automated assembly lines.

Unique Advantages of Sinowon’s Solution

• Solves High Reflection Measurement Issues: For glossy ceramics, configured with coaxial and multi-angle programmable ring lights to enhance edge contrast, ensuring stability in Video measuring system operations.
• Non-contact Safe Inspection: Completely non-contact measurement avoids scratching expensive ceramic finished products, protecting surface smoothness.
• Efficiency & Data Traceability: Supports batch programming and automatic operation. Measurement data can be stored in real-time and generated into SPC reports, helping managers monitor dimensional fluctuation trends on production lines.
• Process Feedback Improvement: Through data feedback, suppliers can adjust processes (e.g., tape casting) in time, reducing rejection rates.

Conclusion

Whether for white alumina ceramics, black silicon carbide ceramics, or high-precision aluminum nitride ceramic substrates, Sinowon provides precision dimensional inspection solutions that are "capable, accurate, and fast."
