When soldering or pre-tinning stranded wire or cables you should only
use an RMA flux followed by an immediate dipping in IPA. Whatever flux
you use will be wicked up under the insulation or within the exposed
strands and cannot be completely cleaned away. This can cause a
potential corrosion issue. Sealing with heatshrink is irrelevant, the
connections can corrode anyway, with or without heatshrink tubing.

Note! A no-clean flux is NOT the same as an RMA flux, and should not be
used to tin stranded wires. WS fluxes should not be used for tinning.

Subject: [TN] Flux on cable wires

Hi,

Does flux cause a problem on cable wiring to connector soldered pins if
they are sealed with heatshrink?  Or will the connections corrode
anyway?

Thanks!
