Claim 3:
4. An electromagnetic shielding structure, comprising:
a circuit substrate, the circuit substrate being provided with at least two spaced circuit units;
at least two non-conductive plastic sealing bodies arranged in a one-to-one correspondence with the at least two circuit units, and at least one spacing groove formed between the at least two non-conductive plastic sealing bodies; and
a conductive shielding layer, the conductive shielding layer covering the at least two non-conductive plastic sealing bodies, and filling the at least one spacing groove to form at least one shielding barrier wall, thereby shielding between neighboring circuit units of the at least two circuit units in respective cavities, wherein the conductive shielding layer is formed by filling a compression mold with a conductive plastic sealant, pressing the circuit substrate into the compression mold so that the conductive plastic sealant fills the at least one spacing groove and covers the at least two non-conductive plastic sealing bodies, and solidifying the conductive plastic sealant to form the conductive shielding layer.
