The 63\/37 eutectic ratio means the alloy transitions directly from liquid to solid without a plastic phase, producing reliable, low-resistance joints. At 21 gauge with a 58-core flux configuration, this solder feeds smoothly through standard soldering irons and stations. It is used primarily for precision electronics assembly, PCB rework, and electrical connection work where a clean, low-residue flux is required. Licensed electricians, electronics technicians, and skilled HVAC controls technicians are the typical end users.\u003c\/p\u003e\n\u003cp\u003eThis solder is suited for through-hole and surface-mount rework applications in both residential and light commercial environments. The mildly activated rosin flux provides enough activation to cut through light oxidation on component leads and pads without leaving the aggressive residue associated with fully activated (RA) flux cores. It is well matched to applications where post-solder cleaning is preferred but not always mandatory, including control board repair, low-voltage wiring terminations, and sensor lead connections.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e63\/37 eutectic tin-lead alloy delivers a sharp liquid-to-solid transition for clean, consistent joints\u003c\/li\u003e\n  \u003cli\u003eMildly activated rosin (RMA) flux core reduces oxidation without heavy post-solder residue\u003c\/li\u003e\n  \u003cli\u003e58-core flux construction ensures even flux distribution throughout the solder wire\u003c\/li\u003e\n  \u003cli\u003e21 gauge diameter suits fine-pitch component work and precision rework tasks\u003c\/li\u003e\n  \u003cli\u003e1-pound spool provides substantial working quantity for bench or field use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose RMA cored solder for electronics assembly, PCB rework, and low-voltage electrical connection applications where a 63\/37 eutectic tin-lead alloy with mildly activated rosin flux is appropriate.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSoldering work on live or energized circuits is hazardous — always de-energize and discharge the assembly before applying solder. Use appropriate ventilation or a fume extractor, as flux vapors are an inhalation hazard. A temperature-controlled soldering iron is recommended to avoid overheating sensitive components or lifting PCB pads. Post-solder cleaning with an appropriate flux remover is advisable on assemblies subject to moisture or condensation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSolder Type\u003c\/strong\u003e: Mildly Activated Rosin (RMA)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAlloy Composition\u003c\/strong\u003e: 63\/37 Tin-Lead\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGauge\u003c\/strong\u003e: 21\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCore Count\u003c\/strong\u003e: 58\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNet Weight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1.125 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1429563RMP20311\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700480540978,"sku":"1429563RMP20311","price":68.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f44c9a2214500b36535945d253eb1c2.jpg?v=1788390870","url":"https:\/\/voomisupply.com\/products\/value-collection-1429563rmp20311-rosin-solder-63-37","provider":"Voomi Supply","version":"1.0","type":"link"}
