唔係叫 solder flux 咩 點解變在叫 paste
Solder paste 應該 係 錫膏
Solder flux 先係 助焊劑

Detail explanations of solder paste and solder flux

    Solder paste (not soldering paste) is tiny bits of solder mixed up with flux. It's all in one, and designed for reflow operations. (Assemble entire board, them heat it all once.)

Solder paste has a lousy shelf life, for multiple reasons, including the fact that the solder is heavy and settles out.

Solder flux is just part of that. You need separate solder, usually in the form of wire. This is designed for hand-soldering, with a soldering iron.

Flux comes in various consistencies, from liquid to gel to thick paste. That might have been what confused them.
