2UUL SC19 Mr. Flux 100 for PCB Repair 100g

In a busy repair shop, a 10 cc syringe of flux can be used up in a few days. Buying in bulk keeps costs down and means the bench doesn't run dry halfway through a job.

The 2UUL SC19 Mr. Flux 100 holds 100 g of flux. According to the listing, it's acid-free, halogen-free and no-clean, gives off little smoke or odour, and is thick enough to stay in place on sloping or crowded areas.

Jobs it covers

• Pads that tin poorly or won't form a bright joint.

• Cold joints and dry connections that cause intermittent faults.

• BGA reballing and chip rework where a syringe would run out too quickly.

• Flux that runs off when the board is tilted, so the joint fails to wet.

Using a bulk jar

Transfer a small amount into a syringe or dish for daily use, so the main supply stays clean and sealed. Apply a thin layer to the joint before soldering.

Keep the jar sealed and away from heat, and use clean tools so the flux stays uncontaminated. That way the last gram works as well as the first.
