Solder Wick

G'day! You're in the shed, working on a little electronics project. You've got the soldering iron hot, and you're ready to go. But... bugger. You've accidentally bridged two connections with a massive, ugly blob of solder, or you've put a component in the wrong spot and need to get it out.

Trying to fix it with more solder is a recipe for disaster. What you need to do is remove the old solder. And while a solder sucker pump is good for big blobs, for a clean, professional finish, you need a different tool. You need solder wick.

What's the Go with Solder Wick, Anyway?

Solder wick, also known as desoldering braid, is a fair dinkum clever bit of kit. It's a finely woven braid of copper wire that has been coated in a chemical called flux.

Its one and only job is to suck up molten solder. It works by using a process called 'capillary action' – the same thing that draws water up a plant stem. When you heat the braid and the solder joint at the same time, the molten solder is magically 'wicked' up into the copper braid, leaving your circuit board clean.

Solder Wick vs. a Solder Sucker: What's the Difference?

This is a common question, mate.

  • A Solder Sucker (Desoldering Pump) is the brute force method. It's a spring-loaded vacuum pump that you use to suck up a big, molten blob of solder all at once. It's fast, but it can sometimes leave a bit of solder behind.
  • Solder Wick is the finesse tool. It's what you use after the sucker, or for delicate jobs. It's perfect for removing that last, thin film of solder from a circuit board pad, leaving it schmick and ready for a new component.

How to Use Solder Wick Like a Pro (It's Too Easy, Mate!)

Ready to give it a burl? It's dead easy once you get the technique.

Step 1: Safety First! Chuck on your safety glasses. Hot solder and flux can spit, and you don't want that stuff anywhere near your peepers.

Step 2: Get Your Gear Ready Get your soldering iron properly hot. Grab your roll of solder wick and unroll a fresh, clean bit of the braid.

Step 3: The Technique (Iron on Braid, Braid on Joint) This is the most important part.

  • Place the fresh end of the solder wick on top of the old solder joint you want to remove.
  • Now, press the hot tip of your soldering iron on top of the braid. Hold it there.
  • This will heat both the braid and the old solder underneath it at the same time.

Step 4: Watch the Magic Happen After a second or two, you'll see the old solder melt and literally get sucked up into the copper braid, turning the copper braid a shiny silver colour. You'll see it wicking right up the braid.

Step 5: Lift and Snip Once the solder is gone, lift both the soldering iron and the solder wick away at the same time. Be quick, or the braid might cool and stick to the board.

Step 6: Clean Up You'll now have a section of braid that's full of old, hard solder. Grab some snips and cut that used bit off, so you have a fresh, clean end of flux-coated braid ready for the next job. You're sorted!

The CRUCIAL Safety Warning: Low-Voltage Only, Mate!

Righto, this is the most important bit, mate. This whole guide – using a solder wick and a soldering iron – is ONLY for hobbyist electronics and extra-low-voltage (like 12V or 24V) DIY jobs. We're talking circuit boards, car electrics, kids' toys, and that sort of thing.

Under no circumstances should you EVER attempt to use a soldering iron or solder wick on your home's 240V mains wiring. This is the wiring in your walls, power points, and light fittings.

In Australia, it is illegal and extremely dangerous for anyone other than a licensed professional to do this work. This kind of hard yakka is strictly a job for a licensed electrician.

From Hobby Repairs to Professional Installations

A solder wick is a ripper tool for any DIYer's kit, allowing you to repair and modify your own low-voltage gear.

But the work of a qualified professional isn't about repairing old bits; it's about installing new, high-quality, compliant electrical systems that are safe and built to last. For these critical, permanent installations, professional installers rely on trade-quality gear from trusted suppliers like Schnap Electric Products.

Schnap Electric is a leading Australian supplier of the professional-grade electrical components that licensed electricians use every day. From the high-quality power points and light switches to the essential circuit breakers and safety switches in your switchboard, they provide the gear that forms the backbone of a safe, modern electrical system. It's a reminder that while a solder wick is great for fixing a hobby kit, a pro uses the right, compliant components from a supplier like Schnap Electric to build a system that's safe and built to last.
