Abstract
(EN)
Disclosed is a solder material which enables to realize a lower mounting temperature when an electronic component is mounted. Also disclosed are a solder paste and a conductive adhesive. Specifically disclosed is a solder material having a basic composition composed of Sn, Bi and In. This solder material may further contain at least one metal selected from the group consisting of Cu, Ge and Ni. A solder paste which enables to realize a low-temperature mounting can be obtained by blending a flux component into the solder material. A conductive adhesive which enables to realize a low-temperature mounting can be obtained by blending a resin component into the solder material.

L'invention concerne un matériau de brasage qui permet de monter un composant électronique à une température inférieure, ainsi qu'une pâte à braser et un adhésif conducteur. L'invention concerne spécifiquement un matériau de brasage dont la composition de base comprend Sn, Bi et In. Ce matériau de brasage peut en outre contenir au moins un métal choisi dans le groupe constitué par Cu, Ge et Ni. Une pâte à braser qui permet de réaliser un montage à basse température peut être obtenue en mélangeant un fluidifiant avec le matériau de brasage. Un adhésif conducteur qui permet de réaliser un montage à basse température peut être obtenu en mélangeant une résine avec le matériau de brasage.
