In the process, metal salts are formed that are usually very soluble in water and also attract and retain moisture from the environment. Moisture and metal salts together create an electrically conductive medium. This significantly increases the chance of<strong>\u00a0electromigration and corrosion on electronic circuits<\/strong>.<\/p>\n<h2>Consequences<\/h2>\n<p>Electromigration and corrosion often result in electric currents finding other paths to flow than the intended ones. This can have various consequences for the operation of an electronic circuit;\u00a0<strong>malfunctioning, misinterpretation of data, component failure and even the burning out of entire systems<\/strong>.<\/p>\n<p>The metal salt SnCl2 formed by Sn (tin) and Cl (halogen) is almost 100 times more soluble in water than the metal salt PbCl2 formed by lead and chlorine. This means that much more damage can be caused in a lead-free process than in a process containing lead if halogens are used.<\/p>\n<h2>How to prevent halogens in a flux<\/h2>\n<p>It is therefore necessary to always give preference to absolutely halogen-free soldering products. An IPC Class L0 product still allows a quantity of halogens of &lt; 500 ppm according to the J-STD-004B standard.<\/p>\n<p>Interflux\u00ae has a soldering range with \u2018absolutely halogen free\u2019 products including soldering wire, solder flux or solder paste.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<hr \/>\n<h3>More info?<\/h3>\n<p>Leave your details via the<a href=\"https:\/\/smans.com\/contact\/\"><strong>\u00a0contact form<\/strong><\/a>\u00a0and we will contact you as soon as possible!<\/p>\n","protected":false},"featured_media":3371,"template":"","class_list":["post-3370","knowledgeportal","type-knowledgeportal","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.1.1 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>What are halogens doing in a flux and what danger do they pose? - Smans<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/smans.com\/nl\/knowledgeportal\/wat-doen-halogenen-in-een-flux-en-welk-gevaar-leveren-ze-op\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"What are halogens doing in a flux and what danger do they pose? - Smans\" \/>\n<meta property=\"og:description\" content=\"Halogens in a flux Halogens are chemical elements that have the property of reducing metals efficiently.
