The highest quality is essential in cable assembly because only perfect connections guarantee reliable function, especially at high currents and under extreme conditions such as vibrations. With micrograph analysis, Otto Schoch AG offers a precise testing method to analyse and ensure the quality of crimp connections with microscopic precision.

Why is micrograph analysis important?

During the production process, quality defects that are often invisible to the naked eye can arise due to tool wear, temperature differences, material changes or tool changes. A micrograph examination uncovers such defects and provides valuable insights into the quality of the crimp connection.

The advantages of micrograph analysis:

• Precise quality control: microscopic examination of the crimping
• Optimisation of connections: ensuring a gas-tight and even crimping
• Reduction of line resistance: the better the pressing, the lower the electrical resistance
• Long-term reliability: prevents failures due to inadequate connections

What is being tested in the micrograph analysis?

The analysis provides detailed information about:

• Consistency of crimping: How accurately was the contact crimped?
• Gas-tightness: Is the connection sufficiently tight to prevent corrosion?
• Quality of crimping tools: Are the tools used suitable for the wire type and contact size?
• Stranded wire and gap sections: How well has the wire been integrated into the contact?

These tests are crucial to qualify crimp connections and ensure consistently high quality.

When is a cross-section analysis required?

We particularly recommend a cross-section analysis

• For new crimp connections: every new connection should be tested to detect errors at an early stage.
• After tool changes: to ensure that the new tools are working correctly.
• When changing materials: Different materials can influence the crimping result.
• For regular quality control: To detect wear or deviations in the production process.
