The soldering grease removes minor impurities and dissolves oxide layers that would cause insufficiently strong solder joints during soldering. The use of soldering grease is therefore almost essential to ensure good solder joint quality. It can be applied more precisely than soldering fluid because it does not run off. The soldering grease has a corrosive effect after the reaction and must be rinsed off promptly with water or mordant after the soldering process.    <\/p>\n<p>During processing, effective extraction \/ fresh air supply, e.g. by ventilation, must be ensured due to the soldering fumes.<\/p>\n<p>Soldering grease 621 is available in an attractive combination with triangular rods made of <a href=\"https:\/\/zinn-giesserei-goehler.com\/en\/produkt-kategorie\/pure-metals\/tin\/\">Sn99.9 (pure tin)<\/a>, <a href=\"https:\/\/zinn-giesserei-goehler.com\/produkt\/sncu07-loetstab-dreikant\/\">SnCu0.7<\/a> or <a href=\"https:\/\/zinn-giesserei-goehler.com\/produkt\/sncu3-loetstab-dreikant\/\">SnCu3<\/a>.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Soldering fluid, copper, copper alloys<\/p>\n","protected":false},"featured_media":34190,"template":"","meta":{"advanced_seo_description":"","jetpack_seo_html_title":"","jetpack_seo_noindex":false},"product_brand":[],"product_cat":[298,330,300,482],"product_tag":[423,484,483],"class_list":["post-34166","product","type-product","status-publish","has-post-thumbnail","product_cat-alloys","product_cat-tin","product_cat-tin-alloy-solder","product_cat-tin-solders-pasty-solidifying","product_tag-copper-pipes","product_tag-electrical-solders","product_tag-solder","product_shipping_class-free","first","instock","taxable","shipping-taxable","purchasable","product-type-variable"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/zinn-giesserei-goehler.com\/en\/wp-json\/wp\/v2\/product\/34166","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/zinn-giesserei-goehler.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/zinn-giesserei-goehler.com\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/zinn-giesserei-goehler.com\/en\/wp-json\/wp\/v2\/media\/34190"}],"wp:attachment":[{"href":"https:\/\/zinn-giesserei-goehler.com\/en\/wp-json\/wp\/v2\/media?parent=34166"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/zinn-giesserei-goehler.com\/en\/wp-json\/wp\/v2\/product_brand?post=34166"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/zinn-giesserei-goehler.com\/en\/wp-json\/wp\/v2\/product_cat?post=34166"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/zinn-giesserei-goehler.com\/en\/wp-json\/wp\/v2\/product_tag?post=34166"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
