Title:
HEXAHEDRAL SHIELDING DEVICE, ELECTRONIC MODULE APPLYING HEXAHEDRAL SHIELDING DEVICE, AND MANUFACTURING METHOD FOR ELECTRONIC MODULE
Document Type and Number:
WIPO Patent Application WO/2021/135893
Kind Code:
A1
Abstract:
A hexahedral shielding device, comprising a box-like shielding body (10), a sheet-like shielding bottom cover (20), a first connecting terminal (30), a second connecting terminal (40), and a PCB (50). The second connecting terminal (40) is provided with a first supporting protruding portion (401) and a second supporting protruding portion (402), so that the second connecting terminal (40) can be conveniently connected to a first metallized through hole (204) and a second metallized through hole (503) in an automatic welding manner. In addition, the sheet-like shielding bottom cover (20) is further provided with an empty slot (205), and a welding portion (303) of the first connecting terminal (30) is embedded into the empty slot (205), so that the welding portion (303) of the first connecting terminal (30) can be conveniently connected to a first pad (208), a second pad (209), and a side wall copper foil (206) in an automatic welding manner, and finally, the box-like shielding body (10), the sheet-like shielding bottom cover (20), and a reference ground of the PCB (50) are connected together. Compared with the prior art, automatic welding operation can be implemented in a whole process, the welding quality is high, the operation efficiency is high, the machining cost is low, and large-scale batch production is facilitated.
