Les halog\u00e8nes dans un flux<\/h2>\n

Les halog\u00e8nes sont des \u00e9l\u00e9ments chimiques qui ont la propri\u00e9t\u00e9 de r\u00e9duire efficacement les m\u00e9taux. Au cours de ce processus, des sels m\u00e9talliques sont form\u00e9s, qui sont g\u00e9n\u00e9ralement tr\u00e8s solubles dans l’eau et qui attirent et retiennent \u00e9galement l’humidit\u00e9 de l’environnement. L’humidit\u00e9 et les sels m\u00e9talliques cr\u00e9ent ensemble un milieu conducteur d’\u00e9lectricit\u00e9. Cela augmente consid\u00e9rablement les risques d’\u00e9lectromigration et de corrosion sur les circuits \u00e9lectroniques<\/strong>.<\/p>\n

Cons\u00e9quences<\/h2>\n

L’\u00e9lectromigration et la corrosion ont souvent pour cons\u00e9quence que les courants \u00e9lectriques trouvent d’autres chemins pour circuler que ceux pr\u00e9vus. Cela peut avoir diverses cons\u00e9quences sur le fonctionnement d’un circuit \u00e9lectronique : dysfonctionnement, mauvaise interpr\u00e9tation des donn\u00e9es, d\u00e9faillance d’un composant et m\u00eame extinction de syst\u00e8mes entiers<\/strong>.<\/p>\n

Le sel m\u00e9tallique SnCl2 form\u00e9 par Sn (\u00e9tain) et Cl (halog\u00e8ne) est presque 100 fois plus soluble dans l’eau que le sel m\u00e9tallique PbCl2 form\u00e9 par le plomb et le chlore. Cela signifie que l’utilisation d’halog\u00e8nes peut causer beaucoup plus de dommages dans un processus sans plomb que dans un processus contenant du plomb.<\/p>\n

Comment \u00e9viter les halog\u00e8nes dans un flux<\/h2>\n

Il est donc n\u00e9cessaire de toujours donner la pr\u00e9f\u00e9rence aux produits de soudage absolument sans halog\u00e8ne. Un produit IPC de classe L0 autorise toujours une quantit\u00e9 d’halog\u00e8nes de < 500 ppm selon la norme J-STD-004B.<\/p>\n

Interflux\u00ae dispose d’une gamme de soudage avec des produits \u00ab\u00a0absolument sans halog\u00e8ne\u00a0\u00bb, notamment des fils de soudure, des flux de soudure ou des p\u00e2tes de soudure.<\/p>\n
