Cable and Connector Assemblies Metrology Solution
Quality Inspection and Metrology for Cable and Connectors Assemblies
The cable and connectors industry is the foundation of modern technology, yet it faces an increasingly volatile landscape of technical and environmental demands. As devices become smaller and more powerful, the margin for error effectively vanishes.
Challenges in Cable and Connector Assemblies
Precision Stamping and Tooling Wear
High-speed stamping of thin metal strips into connector pins and terminals demands strict dimensional control. Even minor misalignment or tooling wear can cause axial distortion, terminal deformation, or excessive indentation, compromising structural integrity.
Complex Termination and Crimping
Achieving a secure, gas-tight crimp requires precisely matched tooling and correct crimp height. Tool damage or improper adjustment can cause poor mechanical retention or high contact resistance, leading to wire pull-out or localized overheating and early-life field failures.
The Hurdle of Miniaturisation
As devices shrink, connectors must deliver high electrical performance in increasingly compact designs, driving the use of advanced alloys and high-performance plastics like liquid crystal polymers that must endure extreme thermal stress without cracking or dielectric degradation.
Maintaining Plating Uniformity
Electroplating terminals with gold or tin improves conductivity and corrosion resistance, but maintaining uniform plating thickness is critical. Insufficient or defective surface treatment can expose base metals, increasing oxidation, contact resistance, and long-term signal degradation.
Managing Solder Wicking
During soldered assembly, solder wicking can cause stranded wire to absorb solder beyond the joint, creating a rigid, brittle fracture zone. This rigidity makes the wire prone to snapping under vibration or repeated movement.
Delicate Wire Preparation and Alignment
Stripping requires precise dimensions and alignment to avoid internal damage. Improper insulation removal or conductor nicks create hidden fatigue points that can cause premature failure. As conductor density increases, maintaining these tolerances becomes increasingly difficult for assembly teams
How Metrology Helps
Metrology is indispensable for identifying defects in cables and connectors, ensuring that parts remain within strict tolerances to prevent malfunctions or operational failures. By determining the precise X, Y, and Z coordinates of specific points, metrology systems can detect deviations from designs at an early stage.
Ensuring Dimensional Precision and Geometry Accuracy
A key assembly challenge is ensuring intricate components like connectors and thin foils fit precisely in tight spaces. Metrology provides critical geometry data for inspecting moulds, tools, and plastic parts, preventing mismatches that cause poor contact pressure, misalignment, and system failure.
Internal Structural Analysis via Computed Tomography
Manufacturers often cannot detect hidden defects inside overmoulded connectors or complex housings without destroying the part. Metrology enables non-destructive internal visualization, allowing inspection for hidden flaws like internal shorts or misaligned pins, ensuring connectors match original designs before field deployment.
Comprehensive Root Cause and Failure Analysis
Recurrent field failures and customer complaints demand thorough investigation. High-resolution inspection reveals microscopic defects—such as solder fractures, corrosion, or residues—that cause intermittent faults. Understanding these root causes enables structured corrective actions to improve long-term reliability.
Process Optimisation and Rework Reduction
Integrating precise measurement across the manufacturing lifecycle, from R&D to mass production, helps detect deviations early. Intelligent software captures and analyses shop-floor data, enabling quality tracking across machines and production lines. This data-driven approach reduces rework and material waste by ensuring parts are “first-time right.”
Verification of Material and Environmental Integrity
Cables and assemblies must endure harsh conditions such as extreme temperatures, vibration, and chemicals. Metrology helps assess material properties and component behavior under stress, ensuring materials won’t prematurely age or fail. Measuring deformation and degradation in simulated environments helps mitigate risks like thermal expansion, brittleness, or dielectric breakdown.
Global Traceability and Regulatory Compliance
For manufacturers operating across multiple locations, maintaining consistent quality is challenging. Metrology ensures parts meet international standards and safety requirements, providing documentation for audits and certifications. Traceable measurement results help sustain quality across the global supply chain, protecting brand reputation and user safety.
