What can happen to a nicked conductor in a solder sleeve area?
A. Just one slight step beyond shield damage from a razor blade is center conductor damage caused by cutting through the shield and grazing the jacket of one or more center conductor wires. This unacceptable condition, when coupled with the use of a solder sleeve for shield termination, can result in intermittent or hard shorts between the braided shield and one or more center conductors. When a solder shield is heated to melt its internal solder ring and shrink the hermetic seal, the heat used will cause any damaged areas of wire jacket to expand, allowing solder to flow in to and harden in the damaged areas. Most often the solder does not create an immediate bridged connection between the shield and a damaged center conductor, but rather excaberates the higher stress point condition in the damaged jacket area of a center conductor. Over time, this can result in one of the hardest-to-trace types of electrical problems – an intermittent ground fault short.
