Part 1: Common Failure Causes of Extremely Fine Coaxial Cable Assemblies

Contact unstable

If the crimping or welding of cables to connector terminals is not accurate, it can easily lead to increased contact resistance and signal interruption, affecting transmission quality.

2, Cable structure damage

Due to the extremely thin diameter of the Micro Coaxial Cable itself, excessive bending, compression, or stretching during assembly or use may cause damage to the internal conductor or shielding layer, resulting in signal attenuation or complete failure.

3. Insertion and extraction wear and fatigue

In scenarios where equipment needs frequent disassembly and assembly, long-term repeated insertion and removal will cause the contact points of the terminals to loosen, resulting in loose connections and intermittent poor performance.

Environmental factors affect

Temperature changes, excessive humidity, dust, and corrosive gases can accelerate the aging of wire harness and connector materials, causing the conductivity to gradually decrease.

5. Static discharge (ESD) interference
Inside precision electronic equipment, static discharge may damage the cable insulation layer, even puncture the terminal structure, affecting the overall system stability.
