MG Chemicals 424-NS, Superwick #2 Yellow, Static Free, No Clean, 1.5mm, Case of 10
MG Chemicals 424-NS No-Clean Superwick is a yellow-coded, 1.5 mm desoldering braid made from tightly woven, oxide-free copper coated with a high-activation-temperature no-clean flux. It draws molten solder into its weave for surface solder cleanup during PCB repair and rework. This listing supplies 10 ESD-safe bobbins, each with a nominal 5 ft length.
Best Uses / Applications
- Surface solder cleanup during PCB repair and benchtop service.
- Surface-mount assembly touch-up where a narrow 1.5 mm braid fits the joint.
- General-purpose solder removal using a qualified iron-and-braid process.
- Repair stations needing yellow-coded braid on ESD-safe bobbins.
Application limitation: The manufacturer overview mentions through-hole repair, but its application instructions say wicking works best for surface solder and is not recommended for solder inside plated-through holes.
Key Features
- Tightly woven, oxide-free copper for fast wicking and reduced dwell time.
- High-activation-temperature no-clean flux.
- Manufacturer-reported non-conductive, non-corrosive residue.
- Yellow #2 identification and 1.5 mm width.
- ESD-safe 5 ft bobbin; not every spool in the broader family is ESD safe.

Match width to the solder area and access. Longer spools do not automatically provide the same ESD-safe packaging as the smaller bobbins.
Using the Braid and Managing Residue
- Remove conformal coating or contamination from the work area.
- Heat the soldering iron using settings qualified for the assembly. For lead-free solder, the TDS suggests starting at about 315°C and adjusting as necessary.
- Place braid on the solder and the iron tip on the braid without contacting adjacent components.
- When wicking ends, lift the iron and braid together.
- Cut off used braid, allow cooling, and repeat as needed.
- Follow the assembly's residue-cleaning and inspection requirements.
Cleaning clarification: The manufacturer's introduction says the non-conductive, non-corrosive residue does not need cleaning, while its current property table recommends cleaning and its application instructions include removal of accumulated flux residue. Follow your validated process and assembly requirements rather than treating “no-clean” as a universal instruction to leave residue.
Safety and Handling
The SDS identifies rosin-related respiratory and skin sensitization hazards. Avoid breathing fumes, use appropriate ventilation and protective equipment, and read the complete SDS before use. Do not use brazing, torch soldering or torch welding methods with this braid. Used braid and solder may remain hot.
Frequently Asked Questions
What width is 424-NS?
It is yellow #2 braid, 1.5 mm wide, with a manufacturer nominal imperial width of 0.06 in.
Is this the 5 ft or 10 ft package?
This 424-NS listing is the 5 ft bobbin, supplied as a case of 10. The 424-NS-10FT is a separate 10 ft package.
Is the bobbin ESD safe?
Yes. The current TDS identifies the 424-NS bobbin as ESD safe. Maintain normal workstation ESD controls.
Does no-clean mean cleaning is never required?
No universal rule should be assumed. The same TDS describes residue as not requiring cleaning but also recommends cleaning in its property table and includes a cleaning step. Follow the assembly's process requirements.
Can it clear solder inside plated-through holes?
The manufacturer's application instructions do not recommend wick for this purpose. It works best on surface solder.
How is this different from 424-LF?
424-NS belongs to the No-Clean Superwick family with high-activation-temperature no-clean flux. 424-LF is separately marketed as Lead-Free Superwick. Use each family's own documents rather than assuming identical formulation or process requirements.
Are the 50 ft NS spools ESD safe?
The manufacturer packaging table marks 453-NS and 454-NS as not ESD safe. Do not extend the 424-NS bobbin's ESD claim to those spools.
What is the shelf life?
The TDS lists ten years with appropriate storage. Keep dry and away from moisture and sunlight; shrink wrapping is recommended for extended storage.
