Title
(EN) ACTIVE SOFT SOLDER FOR ULTRASONIC SOLDERING AT HIGHER APPLICATION TEMPERATURES
(FR) BRASURE TENDRE ACTIVE POUR BRASAGE PAR ULTRASONS À DES TEMPÉRATURES D'APPLICATION SUPÉRIEURES
Abstract
(EN)
Active soft solder for ultrasonic soldering, mainly of non-metal and metal materials, or two non-metal materials, at higher application temperatures, is on the basis of tin and it contains an antimony and an active metal, whereby the share of Sb ranges from 5 to 10% of the mass, the active metal forms 0,1 to 4% of the mass and the rest is Sn. Ti in amount of 0,5 to 4% of the mass and/or La in amount of 0,1 to 2% of the mass can be an active metal. The soft active solder can, in a preferable arrangement, contain Ag in amount of 1 to 30% of the mass, too. The solder is especially suitable for the ultrasonic soldering, where Sn, Sb and active metal support the effective cavitation in wide range of frequencies which achieves strong resulting strength characteristics of the soldered joint even in cases of hard- to-solder materials, without the need of previous coating of the surfaces.
(FR)
La brasure tendre active pour brasage par ultrasons, principalement composée de matériaux non métalliques et métalliques, ou de deux matériaux non métalliques, à des températures d'application supérieures, est à base d'étain et contient un antimoine et un métal actif, la part de Sb étant comprise entre 5 et 10 % de la masse, le métal actif formant 0,1 à 4 % de la masse et le reste étant du Sn. Le Ti en quantité de 0,5 à 4 % de la masse et/ou le La en quantité de 0,1 à 2 % de la masse peut être un métal actif. La brasure tendre active peut également, dans un agencement préférable, contenir de l'Ag en quantité de 1 à 30 % de la masse. La brasure est particulièrement appropriée pour le brasage par ultrasons, où Sn, Sb et le métal actif prennent en charge la cavitation efficace dans une large plage de fréquences, ce qui permet d'obtenir de fortes caractéristiques de résistance résultante du joint soudé même dans les cas de matériaux de brasure tendre, sans avoir besoin d'un revêtement préalable des surfaces.
