Do not nick braid or center conductor. Tin center conductor if contact will be solder attached. Do not tin center conductor if contact is to be crimp attached. A wire stripper of correct size is recommended for this step. Slide heat shrink (as applicable) and crimp sleeve onto jacket of cable. 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. Crimp Attachment (where applicable): Crimp contact to cen- ter conductor using recommended crimp hex. 4. Flare braid and slide body assembly over contact and under braid. Then seat body assembly firmly onto contact. The cable may have to be held in a clamping fixture. Arrange braid uniformly around crimp stem. Slide crimp sleeve forward and crimp using recommended crimp hex. Slide heat shrink forward and shrink (as applicable).
