When used correctly, it removes excess solder quickly without damaging PCB pads or component leads.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This guide explains how desoldering wick works, when to use it, the correct desoldering technique, and how to solve common problems such as solder wick not absorbing solder.<\/p>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 id=\"h-what-is-desoldering-wick\" class=\"wp-block-heading has-text-color has-link-color wp-elements-43273e84adc1ccd3794d15c3ab5bf4f9\" style=\"color:#004f87\"><strong>What Is Desoldering Wick?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Desoldering wick, also called <strong>\u710a\u82af<\/strong> or <strong>desoldering braid<\/strong>, is a braided copper ribbon designed to remove molten solder from PCB pads and component leads.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Most desoldering wicks are pre-coated with a small amount of flux, which helps solder flow from the joint into the copper braid during heating.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike a desoldering pump that removes solder by suction, desoldering wick absorbs solder through <strong>capillary action<\/strong>. Once the solder melts, it naturally flows into the fine copper strands, leaving less solder on the PCB.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because it provides excellent control, desoldering wick is widely used for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>PCB repair<\/li>\n\n\n\n<li>Electronics rework<\/li>\n\n\n\n<li>Removing excess solder<\/li>\n\n\n\n<li>Cleaning solder

class=\"wp-block-heading has-text-color has-link-color wp-elements-b4a6ac06c3528fcd3f4aa4ea74668193\" style=\"color:#004f87\"><strong>How Does Desoldering Wick Work?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Desoldering wick removes solder using two principles:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Heat transfer<\/li>\n\n\n\n<li>Capillary action<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">When the soldering iron heats the braid, heat passes through the copper strands to the solder joint.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Once the solder reaches its melting point, the molten solder is drawn into the braid by capillary action.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Flux further improves this process by removing surface oxides and allowing solder to flow more easily.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For the best results, all three elements must work together:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Proper temperature<\/li>\n\n\n\n<li>Clean copper braid<\/li>\n\n\n\n<li>Adequate flux<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If any of these factors are missing, solder removal becomes much more difficult.<\/p>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 id=\"h-when-should-you-use-desoldering-wick\" class=\"wp-block-heading has-text-color has-link-color wp-elements-e91e2662adfe104677b85f1ce3e26e53\" style=\"color:#004f87\"><strong>When Should You Use Desoldering Wick?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Desoldering wick is ideal when precision is more important than speed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Common applications include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Removing excess solder after soldering<\/li>\n\n\n\n<li>Eliminating solder bridges<\/li>\n\n\n\n<li>Cleaning PCB pads before installing new components<\/li>\n\n\n\n<li>Removing residual solder after using a desoldering pump<\/li>\n\n\n\n<li>Repairing fine-pitch IC solder joints<\/li>\n\n\n\n<li>Correcting soldering mistakes during PCB assembly<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">It is particularly effective for SMD components and small solder joints where precise solder removal is required.<\/p>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 id=\"h-tools-and-materials-you-need\" class=\"wp-block-heading has-text-color has-link-color wp-elements-b6c30d7d9f4b29eda7f9f5b1e306d834\" style=\"color:#004f87\"><strong>Tools and Materials You Need<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Before starting, prepare the following tools:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Temperature-controlled soldering iron<\/li>\n\n\n\n<li>Desoldering wick<\/li>\n\n\n\n<li>Rosin flux or no-clean flux<\/li>\n\n\n\n<li>Soldering iron stand<\/li>\n\n\n\n<li>Brass wool or brass sponge<\/li>\n\n\n\n<li>Isopropyl alcohol for cleaning<\/li>\n\n\n\n<li>Tweezers (optional)<\/li>\n\n\n\n<li>PCB holder (recommended)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Using a temperature-controlled soldering station provides more consistent heat transfer and reduces the risk of PCB damage.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><a href=\"https:\/\/gordakelec.com\/zh\/product\/gordak-9608a-hot-air-soldering-station.html\/\" target=\"_blank\" rel=\"

class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 id=\"h-step-1-heat-the-soldering-iron\" class=\"wp-block-heading has-medium-font-size\"><strong>Step 1 \u2013 Heat the Soldering Iron<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Set the soldering station to an appropriate temperature.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Typical settings are:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Leaded solder<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">320\u00b0C-350\u00b0C<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Lead-free solder<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">350\u00b0C\u2013380\u00b0C<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The exact temperature depends on the solder alloy, PCB thermal mass, and tip size.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 id=\"h-step-2-apply-additional-flux\" class=\"wp-block-heading has-medium-font-size\"><strong>Step 2 \u2013 Apply Additional Flux<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Although many desoldering wicks contain flux, applying a small amount of fresh flux usually improves solder removal.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Additional flux helps:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Reduce oxidation<\/li>\n\n\n\n<li>Improve solder wetting<\/li>\n\n\n\n<li>Increase heat transfer<\/li>\n\n\n\n<li>Speed up solder absorption<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Professional technicians rarely rely on the flux already contained in the braid.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 id=\"h-step-3-position-the-desoldering-wick\" class=\"wp-block-heading has-medium-font-size\"><strong>Step 3 \u2013 Position the Desoldering Wick<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Place the braid directly on top of the solder joint.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ensure it fully covers the solder that needs to be removed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Avoid placing the soldering iron directly onto the PCB first.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The proper order is:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Soldering iron<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2193<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Desoldering wick<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2193<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Solder joint<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This allows heat to transfer efficiently through the braid.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 id=\"h-step-4-heat-the-wick\" class=\"wp-block-heading has-medium-font-size\"><strong>Step 4 \u2013 Heat the Wick<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Press the soldering iron gently onto the braid.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After a few seconds, the solder should begin flowing into the copper braid.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You will usually notice the braid changing color as it absorbs molten solder.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Avoid moving the braid while the solder is still molten.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 id=\"h-step-5-remove-the-wick-and-iron-together\" class=\"wp-block-heading has-medium-font-size\"><strong>Step 5 \u2013 Remove the Wick and Iron Together<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Once enough solder has been absorbed, lift both the soldering iron and the braid away at the same time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Removing them together helps prevent the braid from sticking to the PCB.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Never pull the braid away while the solder is still solidifying, as this may lift PCB pads.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 id=\"h-step-6-cut-off-the-used-section\" class=\"wp-block-heading has-medium-font-size\"><strong>Step 6 \u2013 Cut Off the Used Section<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">After each use, trim away the saturated portion of the braid.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Fresh copper absorbs solder much more efficiently than sections already filled with solder.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Trying to reuse the same section usually produces poor results.<\/p>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 id=\"h-why-won-t-my-desoldering-wick-absorb-solder\" class=\"wp-block-heading has-text-color has-link-color wp-elements-c35a170abd208a9ae8efbec3ac3ea5cb\" style=\"color:#004f87\"><strong>Why Won&#8217;t My Desoldering Wick Absorb Solder?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">One of the most common frustrations is placing the braid on a solder joint only to find that nothing happens.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Several factors may be responsible.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 id=\"h-the-temperature-is-too-low\" class=\"wp-block-heading has-medium-font-size\"><strong>The Temperature Is Too Low<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If the solder never fully melts, it cannot flow into the braid.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Large copper areas, multilayer PCBs, and ground planes often require more heat than small signal traces.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Increasing heat transfer is usually more effective than simply raising the temperature.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 id=\"h-there-isn-t-enough-flux\" class=\"wp-block-heading has-medium-font-size\"><strong>There Isn&#8217;t Enough Flux<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Flux dramatically improves solder flow.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If solder refuses to enter the braid, apply fresh flux before trying again.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This simple step often solves the problem immediately.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 id=\"h-the-wick-has-already-been-used\" class=\"wp-block-heading has-medium-font-size\"><strong>The Wick Has Already Been Used<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Only unused copper braid can absorb additional solder effectively.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the braid has already turned silver, cut it off and continue with a fresh section.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 id=\"h-the-tip-is-oxidized\" class=\"wp-block-heading has-medium-font-size\"><strong>The Tip Is Oxidized<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A dirty or oxidized soldering tip transfers heat poorly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before desoldering, clean and re-tin the tip to improve thermal efficiency.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 id=\"h-the-pcb-has-high-thermal-mass\" class=\"wp-block-heading has-medium-font-size\"><strong>The PCB Has High Thermal Mass<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Large copper pours and multilayer boards absorb heat rapidly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In these situations, use:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A larger soldering tip<\/li>\n\n\n\n<li>Better heat transfer<\/li>\n\n\n\n<li>Slightly longer heating time<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Avoid increasing the temperature excessively.<\/p>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading has-text-color has-link-color wp-elements-aaea7ee18de544d79e20f68d53ac027d\" style=\"color:#004f87\"><strong>Common Mistakes When Using Desoldering Wick<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Even with the right tools, improper technique can reduce desoldering efficiency or damage the PCB. Avoid these common mistakes for cleaner and safer solder removal.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Using Too Much Pressure<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Many beginners press the soldering iron firmly against the braid, expecting it to absorb solder faster.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Excessive pressure does not improve heat transfer. Instead, it can:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Lift PCB pads<\/li>\n\n\n\n<li>Scratch the solder mask<\/li>\n\n\n\n<li>Damage delicate copper traces<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Use only light, even pressure and allow heat to do the work.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Holding Heat for Too Long<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Leaving the soldering iron on the same spot for an extended period can overheat the PCB.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Prolonged heating may cause:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Lifted pads<\/li>\n\n\n\n<li>Delamination<\/li>\n\n\n\n<li>Component damage<\/li>\n\n\n\n<li>Burned flux residue<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If the solder does not melt within a few seconds, stop and identify the cause instead of continuing to apply heat.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Using the Same Section of Wick Repeatedly<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Once a section of braid is saturated with solder, it can no longer absorb effectively.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Always trim off the used portion and continue with fresh braid.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Trying to reuse the same section usually wastes time and transfers unnecessary heat to the PCB.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Skipping Additional Flux<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Although most desoldering wicks contain flux, the amount is often insufficient for older or oxidized solder joints.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Adding fresh rosin flux before desoldering improves:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Heat transfer<\/li>\n\n\n\n<li>Solder wetting<\/li>\n\n\n\n<li>Absorption speed<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This is one of the simplest ways to improve desoldering performance.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Using an Oxidized Soldering Tip<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A blackened or poorly maintained tip cannot transfer heat efficiently.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before desoldering:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Clean the tip<\/li>\n\n\n\n<li>Remove oxidation if necessary<\/li>\n\n\n\n<li>Apply a fresh layer of solder<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A properly tinned tip heats both the braid and the solder joint more effectively.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><a href=\"https:\/\/gordakelec.com\/zh\/product\/gordak-868d.html\/\" target=\"_blank\" rel=\" noreferrer

style=\"color:#004f87\"><strong>Desoldering Wick vs. Solder Pump<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Both tools remove solder, but they are designed for different applications.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th><strong>\u7279\u70b9<\/strong><\/th><th><strong>Desoldering

class=\"wp-block-paragraph\">For example, a solder pump removes most of the solder from a through-hole joint, while desoldering wick cleans the remaining residue before the component is removed.<\/p>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading has-text-color has-link-color wp-elements-bab6450ce110aa42cc690d032b3f2521\" style=\"color:#004f87\"><strong>When Should You Use Hot Air Instead?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Desoldering wick is highly effective for removing surface solder, but it is not suitable for every repair.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A hot air rework station is often a better choice for components that require multiple solder joints to melt simultaneously.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Examples include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>QFN packages<\/li>\n\n\n\n<li>Large QFP ICs<\/li>\n\n\n\n<li>Multi-pin connectors<\/li>\n\n\n\n<li>Shielding covers<\/li>\n\n\n\n<li>Components with thermal pads underneath<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Attempting to remove these components using only desoldering wick can be slow and may increase the risk of PCB damage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Hot air provides more even heating across the entire component, making removal safer and more efficient.<\/p>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading has-text-color has-link-color wp-elements-bbc6ecfb4e93c73cbea0b37083c16beb\" style=\"color:#004f87\"><strong>Professional Tips for Better Desoldering Results<\/strong><\/h2>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Add Fresh Solder Before Desoldering<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This may seem counterintuitive, but experienced technicians often add a small amount of fresh solder before removing old solder.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Fresh solder introduces new flux and improves heat transfer, making older solder easier to remove.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This technique is especially helpful when working with oxidized joints or lead-free solder.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Match the Tip Size to the Joint<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A tip that is too small may struggle to deliver enough heat.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For larger pads or ground connections, use a tip with greater contact area to improve thermal transfer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The correct tip size often has a greater impact on desoldering performance than increasing the temperature.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Use Quality Desoldering Wick<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Not all desoldering braid performs the same.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">High-quality wick generally features:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Tightly woven copper braid<\/li>\n\n\n\n<li>Consistent thickness<\/li>\n\n\n\n<li>Effective flux coating<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Better-quality braid absorbs solder faster and reduces heating time.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>\u56fa\u5b9a\u5370\u5237\u7535\u8def\u677f<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Holding the PCB steady makes desoldering more controlled and reduces the risk of accidental movement.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A PCB holder or helping hands tool allows both hands to remain focused on the soldering iron and the braid.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Clean the PCB After Desoldering<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Flux residue can attract dust and make inspection more difficult.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After the PCB has cooled, clean the repaired area with isopropyl alcohol and a lint-free swab if your flux requires cleaning.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This leaves the board cleaner and makes it easier to inspect solder joints.<\/p>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 id=\"h-faqs\" class=\"wp-block-heading has-text-color
