Inspect the Mating Plane Surfaces
Flat contact between the connectors at all points on their mating plane
surfaces is required for a good connection. See Figure 3-6 on page 3-10 .
Look especially for deep scratches or dents, and for dirt and metal particles on
the connector mating plane surfaces. Also, look for “dings” on the mating
plane surfaces of the center and outer conductors, and look for signs of
damage due to excessive or uneven wear or misalignment.
Light burnishing of the mating plane surfaces is normal, and is evident as light
scratches or shallow circular marks distributed more or less uniformly over the
mating plane surface. Other small defects and cosmetic imperfections are also
normal. None of these affect electrical or mechanical performance.
Clean and inspect the connector again, if it shows:
— Deep scratches or dents
— Particles clinging to the mating plane surfaces
— Uneven wear
