Abstract

L'invention concerne un système de liaison pour une carte portant un circuit imprimé (1), comprenant au moins un premier élément de liaison (2) et un deuxième élément de liaison (3). Le premier élément de liaison (2) est formé d'un premier film conducteur (21) et d'un deuxième film conducteur (22). Le premier film conducteur (21) est imprimé sur une première face (A) de la carte de circuit imprimé (1), tandis que le deuxième film conducteur (22) est imprimé sur une deuxième face (B) de la carte de circuit imprimé (1). Selon l'invention, le deuxième élément de liaison (3) comprend un premier ressort (31) et un deuxième ressort (32). Le premier ressort (31) et le deuxième ressort (32) sont configurés de manière à ce que la pression du premier ressort (31) sur le premier film conducteur (21) et la pression du deuxième ressort (32) sur le deuxième film conducteur (22) établissent un contact galvanique entre le ressort (31, 32) et le film conducteur (21, 22).
