Abstract

The packaging method comprises the following steps: mounting an electronic element on the surface of a circuit board; the surface of the circuit board is covered with peelable glue, the peelable glue surrounds the electronic element, and the peelable glue and the electronic element are arranged at intervals; covering a mold on the peelable glue, defining an accommodating space by the mold, the circuit board and the peelable glue, and accommodating the electronic element in the accommodating space; after injecting a packaging material into the accommodating space, solidifying the packaging material to form a packaging layer in the accommodating space; and removing the mold, and removing the peelable glue to obtain the packaging structure. The packaging method is wide in applicability and low in production cost. The invention also provides a packaging structure.
