Each time you remove solder, you must trim the end of your homemade desoldering braid to remove that used solder.ĭon’t Forget About Coaxial Cable Shielding Remember to trim your homemade desoldering braid after each use – The desoldering braid works by drawing the solder away from the solder joint and into the braid or twisted wire.In some cases, you will find it almost impossible to melt old solder without flux. Flux is the real trick to making your desoldering braid or wick. Add flux to the bare copper or aluminum wire – Add flux to the bare copper or aluminum wire.

How to Make Your Own Desoldering BraidĪlmost any stranded fine-gauge copper or aluminum wire will work as desoldering braid. Desoldering braid or wick comes in a variety of widths to match your project. These products can usually be found at electronic supply stores or ordered from the internet. There are several brands of desoldering braid available on the market. This pre-fluxed copper braid is usually sold in small rolls with a tight-fitting lid to keep the solder flux from evaporating. What is Desoldering Braid?Ĭommercially available desoldering braid or wick is essentially a copper braid impregnated with soldering flux. Here are a few tips to help you make your desoldering braid and the best practices for desoldering. Making your desoldering braid depends on your understanding of how soldering works. The success of the desoldering is as much about the desoldering technique as it is about the tools. When using copper, aluminum, or coaxial cable shield, add a bit of liquid solder flux to the wire to assist the capillary action that removes the solder.Īny of these substitutes will work for desoldering if you don’t have desoldering braid.
You can make functional substitutes for desoldering braid using a small length of stranded copper or aluminum wire or the braided shielding on coaxial cable. If you are out of desoldering braid, what is a good desoldering braid substitute?
Removing old electronic parts requires removing the solder connecting the parts to the circuit board. Salvaging electronic parts from old circuit boards is a time-tested means of saving money and recycling old electronics into new projects. This report examines the chemistry of this material under simulated soldering conditions in an effort to gain an improved understanding of thermal reactions and degradation products which may have an effect on long-term reliability of military electronic hardware.“This post contains affiliate links, and I will be compensated if you make a purchase after clicking on my links.” Citric acid offers excellent fluxing ability, efficient removal of residues with water, and non-ionic flux formulations. However, a new flux ingredient, citric acid, is gaining favor within the electronics manufacturing industry.
Until recently, the military has not allowed this type of flux because of the highly corrosive fluxing action usually associated with these materials. The use of water soluble flux offers an attractive option because all cleaning would be accomplished using only water. Electronics are a particularly challenging problem because efficient removal of post soldering flux residues is critical to the long-term performance of high reliability electronics. Abstract: As a result of the phase-out of ozone-depleting chemicals ODC, the military and its contractors are facing the problem of developing alternative materials and processes which currently employ these materials.
