For example, the first direction a is the longitudinal direction of the shield case 300 shown in the figure.

第一侧壁11和第二侧壁12中至少一者的远离顶壁10的一端(例如图中所示的下端)沿第一方向a的尺寸小于顶壁10沿第一方向a的尺寸。The dimension of at least one end of the first side wall 11 and the second side wall 12 away from the top wall 10 (eg, the lower end shown in the figure) along the first direction a is smaller than the dimension of the top wall 10 along the first direction a.

例如,在屏蔽罩300与电路板100采用焊接的方式连接时,第一连接层15可以是设置在电路板100上的第一焊盘,第二连接层16可以是设置在电路板100的上的第二焊盘。屏蔽罩300通过第一侧壁11的远离顶壁10的一端与第一连接层15连接,屏蔽罩300还通过第二侧壁11的远离顶壁10的一端与第二连接层16连接。For example, when the shielding case 300 and the circuit board 100 are connected by welding, the first connection layer 15 may be the first pad disposed on the circuit board 100 , and the second connection layer 16 may be disposed on the circuit board 100 . of the second pad.

Correspondingly, the size of the first pad along the first direction a may be set to be smaller than the size of the top wall 10 along the first direction a, and the size of the second pad along the first direction a may be set to be smaller than the size of the top wall 10 Dimension along the first direction a.

在其他实施例中,可以是第一侧壁和第二侧壁其中一者的远离顶壁的一端沿第一方向的尺寸小于顶壁沿第一方向的尺寸,另一者的远离顶壁的一端沿第一方向的尺寸等于顶壁沿所述第一方向的尺寸In other embodiments, the dimension of one end of the first side wall and the second side wall away from the top wall along the first direction is smaller than the dimension of the top wall along the first direction, and the dimension of the other end away from the top wall The dimension of one end along the first direction is equal to the dimension of the top wall along the first direction

通过上述方式,将第一侧壁11和第二侧壁12的下端沿第一方向a的尺寸均设置为小于顶壁10沿第一方向a的尺寸,可以使得第一焊盘和第二焊盘沿第一方向a的尺寸均小于顶壁10沿第一方向a的尺寸,一方面,可以使得顶壁10在电路板100的投影完全覆盖被屏蔽物200,保证屏蔽罩300的对被屏蔽物200的保护功能和屏蔽功能,另一方面,由于第一焊盘和第二焊盘尺寸小于顶壁尺寸使得,第一焊盘和第二焊盘可以让出空间方便被屏蔽物200与周围电路之间的走线布局。In the above manner, the size of the lower ends of the first side wall 11 and the second side wall 12 along the first direction a is set to be smaller than the size of the top wall 10 along the first direction a, so that the first pad and the second solder pad can be The size of the disk along the first direction a is smaller than the size of the top wall 10 along the first direction a. On the one hand, the projection of the top wall 10 on the circuit board 100 can completely cover the shielded object 200 to ensure that the shielding cover 300 is shielded against the shielded object 200. On the other hand, since the size of the first pad and the second pad is smaller than the size of the top wall, the first pad and the second pad can leave space to facilitate the shielded object 200 and the surrounding Trace layout between circuits.
