| description | The invention discloses a gradient aluminum-silicon packaging shell. The gradient aluminum-silicon packaging shell comprises a packaging bottom plate and a packaging side plate, the packaging side plate and the packaging bottom plate jointly form a cavity for assembling an electronic element, the thickness of the packaging bottom plate is 2-5 mm, and the packaging bottom plate is made of, by volume, 50-70% of silicon and the balance aluminum. The packaging side plate is provided with at least two layers of structures from bottom to top according to the distribution of the silicon content, thesilicon content is distributed in a gradient manner according to the set number of layers, the content of the lowermost layer structure of the packaging side plate is lower than the silicon content ofthe bottom plate of the sealing plate, the thickness of the uppermost layer structure of the packaging side plate is 2-5mm, and the silicon content of the uppermost layer structure is 24-28%. The gradient aluminum-silicon mat |
