Ce rapport décrit les tests effectués sur des capteurs CentoNewton-B en cours de productions pilotes, dans le but d’utiliser à l’avenir de la brasure sans plomb. S'il est possible d'utiliser une composition conductrice argent peu allié (ESL 9562G) pour les pistes, il est fortement recommandé de finir le renfort avec une composition plus fortement alliée (Ag:Pd ~3:1, ESL 9635G) pour faciliter le mouillage de la brasure. This report details the tests performed on CentoNewton-B sensors, in the frame of pilot production runs, in the goal of using lead-free solder in the future. While it is possible to use a low-alloy silver conductive composition (ESL 9562G) for the tracks, it is strongly recommended to finish the reinforcing layer with a more alloyed composition (Ag:Pd ~3:1, ESL 9635G) to facilitate solder wetting.
