stripper of correct size is recommended for this step. Tin center con-
ductor if contact will be solder attached. Do not tin center conductor
if contact is to be crimp attached.
3. Assemble contact onto cable as shown.
Solder Attachment:
Solder contact to center conductor through hole
using a minimum amount of solder for a good joint.
