Beschreibung
Zusammenfassung:	The present invention provides for a chelate fluxing agent, its use in fluxing compositions, and its use in soldering methods. The fluxing agents as described herein, when combined with a resin such as thermosetting resins, thermoplastic resins or a combination thereof, afford compositions suitable for use as underfill adhesives. The present invention also provides for an electrical component assembly and methods for producing an electrical component assembly including such underfill adhesive compositions. L'invention concerne un fluidifiant chélaté, l'utilisation de celui-ci dans des compositions fluidifiantes et dans des procédés de brasage. Lorsqu'ils sont combinés à une résine, telle que des résines thermodurcissables, des résines thermoplastiques ou une combinaison de celles-ci, les fluidifiants décrits dans cette invention permettent d'obtenir des compositions pouvant être utilisées en tant compositions adhésives à manque de métal.
