Wire Harnesses / Connectors
For automotive wire harnesses, industrial connectors, high-frequency/high-speed interconnects and data cables, covering electrical performance, mechanical life, environmental endurance and material compliance, we verify reliability and consistency in high-frequency/high-speed applications.
You are probably struggling with these issues
These are the things we hear most. If any of the following matches your situation, it is time for a systematic pre-compliance assessment.
Mating life and contact resistance degradation curves are unavailable, and customer audits fail
Crimp defects, waterproofing failures and intermittent contacts only surface at the customer end
High-frequency/high-speed interconnects are judged by signal integrity metrics, but test criteria and target values are unclear
What we do for this industry
Listed here by capability area; specific items are subject to the test plan.
- Electrical Performance: Continuity, contact resistance, insulation resistance, withstand voltage, voltage drop, intermittent contact detection
- Mechanical performance: Mating force, mating life, pull-out force, tear force, bending, torsion
- Environmental Endurance: High/low temperature, temperature-humidity cycling, salt spray, industrial solvent resistance, high temperature and humidity
- Waterproof and dustproof: Connector waterproofing, air tightness, IP rating
- Signal integrity: Characteristic impedance, insertion loss, return loss, eye diagram (with partner laboratories)
- Material compliance: Flame retardancy (needle flame / glow wire / horizontal and vertical burning), restricted substances
- Dimensions and appearance: Dimensional measurement, visual inspection, plating thickness and composition
