The invention relates to a multi-bin shielding mode with a compact structure. In the mode, an instrument circuit is designed onto two PCB boards, a circuit to be shielded is designed on a main PCB board, elements and circuits not needing shielding are designed on an auxiliary PCB board, and the auxiliary PCB board serves as a shielding case cover; a shielding case grid is sandwiched between a shielding case grid contact area on the main PCB board and a shielding case grid contact area on the auxiliary PCB board; contact faces of the shielding case grid and the main and auxiliary PCB boards are cushioned with conductive adhesive tapes; and the main and auxiliary PCB boards, the conductive tapes, and the shielding case grid form a compact multi-bin shielding structure together. Because the contact faces are provided with the flexible material conductive adhesive tapes, the shielding space has no gap, the shielding effect on a high frequency circuit is good, the materials are not wasted, the ...
