The invention relates to an anti-splashing
chip pre-packaging cover body and a
chip pre-packaging method, the anti-splashing
chip pre-packaging cover body comprises an annular wall and a mold sheet layer, and the annular wall and the mold sheet layer are both made of
polydimethylsiloxane; one end of the annular wall is connected to the
peripheral edge of the mold sheet layer, the annular wall is perpendicular to the mold sheet layer, and a concave structure which is arranged corresponding to a pattern on a pre-packaged chip and has the same shape as the pattern on the pre-packaged chip is formed on one side surface, close to the annular wall, of the mold sheet layer; the inner side wall of the annular wall is matched with the
peripheral edge of the pre-packaged chip, and the axial height of the annular wall is larger than the thickness of the pre-packaged chip, so that when the inner side wall of the other end of the annular wall is fixed to the
peripheral edge of the pre-packaged chip, an avoiding gap is reserved between the inner surface of the mold sheet layer and the top of the pre-packaged chip. The surface of the
surface acoustic wave filter can be isolated, so that splashes generated in the
welding process are effectively isolated, the filter is protected against
pollution, meanwhile, the packaging process is simplified, the cost is reduced, and the production efficiency and the product quality are improved.
