Why do I need flux if my solder already has a rosin core?

Because the core flux burns off in the first moment of contact. On rework — lifting a chip, drawing solder with wick, reflowing a joint — you need flux present for the whole operation, and that has to come from a bottle.

Do I have to clean flux off afterwards?

Yes. Residue is mildly conductive and draws moisture, so it creates leakage paths between pads. Clean the board with isopropyl alcohol and a brush before reassembly.

Soldering flux for phone board repair and rework.

Flux does one essential job: it strips the oxide layer off metal so molten solder can actually wet the surface. Without it solder beads up and sits on top of a pad instead of bonding to it, which is what a cold joint is. Almost every soldering problem a technician blames on a tip or a station is really a flux problem.

Key features

Removes oxidation so solder wets the pad properly
Improves flow and joint strength
For phone board repair and rework

What this is used for

Improving solder wetting
Chip removal and refitting
Wick-based pad cleaning

Who it's for

Micro-soldering technicians.
