Abstract
A PCB, a cell battery assembly including the PCB, and a welding method using the PCB are discussed. The PCB may include a first layer including a weld spot for laser welding, and a laser blocking portion included in a second layer disposed under the first layer. The laser blocking portion may be located at a same position as the weld spot in a direction in which the first layer and the second layer are stacked. The laser blocking portion may include a material configured to reflect a laser radiated for welding at the weld spot or prevent the laser from passing therethrough while the weld spot is being welded.
Claims11
A printed circuit board (PCB) comprising:
- a first layer comprising a weld spot for laser welding;
- and
- a second layer under the first laver, and including a laser blocking portion, the laser blocking portion being located at a same position as the weld spot in a direction in which the first layer and the second layer are stacked,
- wherein the laser blocking portion comprises a material configured to reflect a laser radiated for welding at the weld spot or prevent the laser from passing therethrough while the weld spot is being welded.
