Electrical Industry
Dimensional inspection of electrical components ensures that parts meet design specifications, function correctly, and fit properly within assemblies. This type of inspection measures physical attributes such as length, width, height, diameter, thickness, and geometric tolerances.
Common Inspection Methods:
Calipers & Micrometers
Used for basic dimensional measurements.
Coordinate Measuring Machines (CMMs)
Provide high-precision 3D measurements.
Optical Comparators & Vision Systems
Use cameras and software for non-contact measurement.
Laser Scanning & 3D Profilometry
Capture complex geometries and surface profiles.
X-ray & CT Scanning
Inspect internal structures and verify hidden dimensions.
Gauge & Fixtures
Custom tools for repeatable measurements of specific features.
Key Parameters Checked:
- Lead spacing and pin dimensions in connectors.
- PCB trace width, hole diameters, and component placements.
- Housing and casing dimensions for enclosures.
- Conformity to GD&T (Geometric Dimensioning and Tolerancing) standards.
