Abstract

La présente invention concerne une carte de circuit de montage de composant électronique (26d) qui comprend : une carte de circuit de montage de composant (26d1) pour monter un composant électronique ; une carte de déchet (26d2) formée au niveau d'une partie d'extrémité de la carte de circuit de montage de composant (26d1), aucun composant électronique n'étant monté sur la carte de déchet (26d2) ; une partie de rainure (26d3) formée entre la carte de circuit de montage de composant (26d1) et la carte de déchet (26d2) ; et une base de borne (63) installée entre la carte de circuit de montage de composant (26d1) et la carte de déchet (26d2) et couvrant la partie de rainure (26d3), la base de borne (63) étant fixée sur la carte de circuit de montage de composant (26d1). La carte de déchet (26d2) possède un trou d'encoche (26d21) qui est plus grand que la partie de surface inférieure de la base de borne (63) dans une région où la partie de surface inférieure de la base de borne (63) fait saillie dans la direction de la carte de déchet (26d2). La carte de déchet (26d2) n'a pas de contact avec la base de borne (63) en raison du trou d'encoche (26d21).
