A slightly different process of prepping an older lot of tin plated cable involves a burnishing of the outer surface to remove slight tin oxidation.

This could reduce time and dwell time in any soldering operation and can eliminate the removal or wicking of the tin plating into the solder which could expose copper.

The task of burnishing the tin plating is required on the ends of the cut cable and only completed with a chemical free “Kimwipe”.

The end prepping with the Kimwipe should make the cable ends brighter and somewhat polished.

Finger cots are a good idea to wear with this processing for new lots as well as the older lots.

The cable might have been slightly oxidized from its storage especially if stored outside of its original packaging from the supplier which is not recommended.

Never use anything abrasive such as steel wool or a scotchbrite pad as these products will grind in more contaminates than it removes.

For space requirements consider “chemically prepping” the cable with Kesters “Coppernu" for copper semi-rigid or “Soldernu” for tin plated cable.

These products contain Fluoroboric acid.

SPC’ing for concave solder joints, solder rings for vertical induction, care with tweezing if resistive, and the temp and dwell controlled solder stations like Metcals should be used.
