Complex sensing device packaging structure and packaging method
A complex sensing device packaging structure and packaging method are disclosed. The packaging structure includes a substrate disposed with a light emitting element and a light sensing chip. A first non-transparent material is disposed on the light sensing chip. A transparent molding material surrounds the light emitting element, the light sensing chip and the first non-transparent material. A second non-transparent material is disposed inside the transparent molding material, and the second non-transparent material is connected with the first non-transparent material.
1. A complex sensing device packaging method, comprising:
disposing a light emitting element and a light sensing chip on a substrate;
setting a first opaque material on the light sensing chip;
sealing the light emitting element and the light sensing chip in a transparent molding material, wherein further includes abutting a mold against the first opaque material, injecting a liquid transparent substance into the mold to form the transparent molded material after solidification, and removing the mold abutted against the first opaque material to form a shaping space on the transparent molding material which is connected to the first opaque material; and
filling the shaping space with a second opaque material connected to the first opaque material, so that the first opaque material and the second opaque material together form a shielding element.
