It is the most widely used lead-free solder alloy in electronics manufacturing, offering a good balance of wettability, mechanical strength, thermal fatigue resistance, and cost. It has a melting point of 217°C, slightly higher than traditional Sn63\/Pb37 eutectic solder (183°C).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between solid core and flux-core wire solder?\u003c\/strong\u003e\u003cbr\u003eSolid core wire contains no flux — it is pure alloy wire. You must apply flux separately before or during soldering. Flux-core wire has flux embedded in the center of the wire, which activates during soldering. Solid core is preferred for wave soldering, selective soldering, and applications where flux type and quantity need to be precisely controlled.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat flux should I use with solid core SAC305 wire?\u003c\/strong\u003e\u003cbr\u003eThe appropriate flux depends on your process and cleanliness requirements. No-clean liquid fluxes are most common for wave and selective soldering. Water-soluble fluxes offer stronger activation but require post-solder cleaning. Indium Corporation offers compatible flux products — contact MTE Solutions for recommendations based on your specific process.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this wire RoHS compliant?\u003c\/strong\u003e\u003cbr\u003eYes — SAC305 is a lead-free alloy and fully compliant with RoHS (Restriction of Hazardous Substances) and WEEE directives.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the shelf life of Indium wire solder?\u003c\/strong\u003e\u003cbr\u003eIndium wire solder has an indefinite shelf life when stored properly in a cool, dry environment away from humidity and oxidizing atmospheres. The alloy itself does not degrade, though the spool packaging should be kept sealed when not in use to prevent surface oxidation.\u003c\/p\u003e","brand":"Indium","offers":[{"title":"Default Title","offer_id":39708278685901,"sku":"WIREOT-52441-2268","price":494.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0566\/4181\/4733\/products\/FluxCoredWireArray_2178d192-10cf-45b3-ae41-26370ea36ca0.jpg?v=1632751902","url":"https:\/\/mtesolutionsinc.com\/products\/indium-sac305-solid-wire-125-dia-5lb-spools","provider":"MTESolutions","version":"1.0","type":"link"}
