| titleOfInvention | Composite ceramic substrate and preparation method therefor |
| abstract | Disclosed are a composite ceramic substrate and a preparation method therefor. The composite ceramic substrate comprises: an inner core layer and equal-thickness surface layers composited on two sides of the inner core layer, wherein the difference between thermal expansion coefficients of the inner core layer and the surface layer is Δα; the thickness of the inner core layer is H; the thickness of the surface layer is h; Δα needs to satisfy a first constraint condition, and the first constraint condition is: Δα is less than a first preconfigured value, Δα is less than a second preconfigured value and Δα is greater than a third preconfigured value; and h/H needs to satisfy a second constraint condition, and the second constraint condition is: h/H is greater than or equal to a fourth preconfigured value and is less than or equal to a fifth preconfigured value. By means of the composite ceramic substrate, the technical defect of existing ceramic substrates of mechanical strength being relatively low and the safety and reliability of an encapsulation component thereof being poor can be overcome. |
