MG Chemicals 423 Superwick #1 White Static-Free Desoldering Braid, 1.0mm, Case of 10
MG Chemicals 423 Superwick #1 White Static-Free Desoldering Braid, 1.0mm, Case of 10
MG Chemicals 423 Superwick is 1.0 mm RMA-flux-coated copper desoldering braid for controlled removal of excess solder during PCB rework. The tightly woven, high-purity, oxide-free copper draws molten solder away from the work area quickly, helping reduce dwell time. This #1 version has a white identification label and a 5 ft (1.5 m) ESD-safe bobbin. Supplied as a case of 10.
Best Uses / Applications
For electronics assembly, repair benches, service departments and PCB prototyping: surface-mount touch-up, solder bridge correction, pad cleanup and surface solder removal around through-hole assemblies. The manufacturer's data sheet does not recommend braid for removing solder from plated-through holes; use a process suited to clearing those holes.
Key Features
- Pre-coated with RMA flux for solder wetting and absorption.
- High-purity copper and tight weave support fast heat transfer and wicking.
- 1.0 mm braid width with white color identification.
- ESD-safe bobbin for the 5 ft roll size.
- Non-corrosive residue; post-process cleaning is recommended.
- 400 Series is NSF nonfood compounds program listed.

Superwick Width Comparison
Match the braid width to the solder area being cleaned. These five versions share RMA-flux-coated copper and a 5 ft (1.5 m) ESD-safe bobbin; width and label color distinguish them.
| Part | Width | Label |
|---|---|---|
| 423 | 1.0 mm | White |
| 424 | 1.5 mm | Yellow |
| 425 | 2.0 mm | Green |
| 426 | 2.5 mm | Blue |
| 427 | 3.0 mm | Brown |
Use and Handling
Remove contamination or conformal coating from the work area first. Lay the braid over the solder, then place the heated soldering tip on the braid without contacting nearby components. When wicking stops, lift the iron and braid together. Cut off and discard the used section, allow the area to cool and repeat only as needed. Clean accumulated flux residue with a suitable flux remover. Review the product SDS and your assembly's process requirements before use.
Frequently Asked Questions
What makes 423 different from the other Superwick sizes?
Its 1.0 mm width and white label. All five 423–427 versions have 5 ft ESD-safe bobbins; choose width to match the solder area.
Is the braid already fluxed?
Yes. The copper is pre-coated with RMA flux. Additional flux is optional in the manufacturer’s surface-solder-removal procedure.
Is it no-clean braid?
This is the RMA fine-braid series, not the separate no-clean series. The data sheet recommends cleaning flux residue.
Can it clear solder from plated-through holes?
The manufacturer lists through-hole repair among its applications, but specifically does not recommend this wicking method for removing solder inside plated-through holes. Use it for accessible surface solder cleanup.
Is the entire assembly ESD protected by the bobbin?
The 5 ft bobbin is ESD safe. Continue using your established grounding, handling and workstation controls.
Can I reuse a saturated section?
Cut off and discard the solder-filled section as directed by the manufacturer, then use fresh braid.
