Zusammenfassung: | The present invention relates to a PCB comprising: a first layer including a welding spot for laser welding; and a laser blocking unit included in a second layer, which is the bottom layer of the first layer, and positioned, on the basis of the stacking direction of the first layer and the second layer, at a position which is the same as that of the welding spot, wherein the laser blocking unit includes a material which reflects a laser for welding at the welding spot or which prevents the laser from passing therethrough while the welding spot is welded.
La présente invention concerne une carte de circuit imprimé comprenant : une première couche comprenant un point de soudage pour le soudage au laser ; et une unité de blocage laser incluse dans une seconde couche, qui est la couche inférieure de la première couche, et positionnée, sur la base de la direction d'empilement de la première couche et de la seconde couche, à une position qui est la même que celle du point de soudage, l'unité de blocage laser comprenant un matériau qui réfléchit un laser pour le soudage au niveau du point de soudage ou qui empêche le laser de passer à travers celui-ci tandis que le point de soudage est soudé.
본원발명은 레이저용접을 위한 용접스팟을 포함하는 제1층, 및 상기 제1층의 하부층인 제2층에 포함되며, 상기 제1층 및 제2층의 적층 방향 기준으로 상기 용접스팟과 동일한 위치에 위치하는 레이저차단부를 포함하고, 상기 레이저차단부는 상기 용접스팟에서의 용접을 위해 조사되는 레이저를 반사하거나 상기 용접스팟이 용접되는 동안 상기 레이저가 통과하지 못하는 소재를 포함하는 PCB에 관한 것이다. |
