Abstract
On prévoit des plaquettes de circuit pourvues de traces pouvant constituer des rainures (22) ou des tranchées. Lesdites traces peuvent être remplies, au moins partiellement, d'un matériau conducteur pouvant refondre (24), tel que la soudure. On peut envoyer, de manière sélective, de la soudure dans les rainures (22), tandis que d'autres zones (28) restent vides. Pendant le montage de composants électroniques, avec ou sans câbles allongés, tels que des circuits intégrés de montage en surface ou des plaquettes, on peut placer lesdits câbles dans les zones des rainures sans soudure (des zones de contact) et on peut chauffer ensuite la plaquette, sélectivement ou totalement, de manière à faire fondre la soudure vers les zones de liaison ou de contact afin de lier les traces aux câbles lors du refroidissement. On peut réaliser ainsi des plaquettes de circuit dotées de dispositifs de montage superficiel des deux côtés. En plus, on peut lier, en les plaçant directement sur les traces, des dispositifs montés de liaison automatique par bandes (TAB) auxdites traces, en dénudant au minimum les câbles TAB découpés avant le montage. Dans un mode de réalisation, les rainures (22) sont plaquées cuivre (32) avant d'être remplies de soudure (24).
