Abstract
Disclosed are an electromagnetic shielding structure and a manufacturing method thereof, and an electronic product. The manufacturing method includes covering an injection mold on a circuit substrate, so that different circuit units on the circuit substrate are respectively accommodated in different injection molding cavities of the injection mold; injecting a non-conductive plastic sealant into the injection molding cavities so as to form non-conductive plastic sealing bodies on the circuit units, wherein spacing grooves are formed between the non-conductive plastic sealing bodies; and forming a conductive shielding layer on the non-conductive plastic sealing bodies, so that the conductive shielding layer covers the non-conductive plastic sealing bodies and fills the spacing grooves to form shielding barrier walls, thereby realizing shielding between the different circuit units in respective cavities.
