Good for etch sensitive PCB's Cleaning up residue is simple with a hot, slightly damp rag.
Great for re-tinning your old soldering iron tips after scrubbing.
Not as good as other fluxes for difficult to solder surfaces unless preheated on an abrased surface first.
Etchant takes a while at low temperatures to chemically clean a dirty copper surface, but this is not necessarily a con.
Definitely a good product for electronics or jewelery that utilize easily solderable surfaces.
150 grams is a lot of flux etchant paste for a small price.
It's an OK mild paste suited to electronics work. But if you need to solder more difficult surfaces, get a plumbers grade flux from a hardware store.
