B.3.2 Stripping
Use a cable stripper to strip the cable sheath and inner insulating layer without any
damage to the shielding layer and internal conductor. The end faces of the cable
sheath and inner insulating layer should be flush and smooth. Figure B-8 shows the
specific stripping dimensions (unit: mm).

B.3.3 Soldering Pins
Use the soldering tin with melting point above +125
conductor inside the cable.
During the process, insert the cable conductor into the small central hole at the tail of
the pin until the step at the pin tail contacts the inner insulating layer of the cable, as
shown in Figure B-9.
