[0033] Finally, the present invention provides a method for preparing a ceramic heat dissipation substrate, comprising the following steps:
[0034] A. Casting the upper ceramic slurry, after drying, punching and sintering the upper ceramic green body to obtain the upper ceramic green body; then setting through holes on the upper ceramic green body to form the upper ceramic green body with through holes to obtain the first layer;
[0035] B. The middle ceramic slurry is cast, dried and then punched and glued to obtain a middle ceramic green body; the lower ceramic slurry is casted, dried and then punched and glued to obtain a lower ceramic green body; the lower ceramic slurry is composed of lower ceramic A mixed system of powder and the first organic additive, the lower ceramic powder contains 80-100 parts by weight of alumina, 10-20 parts by weight of strontium lanthanum manganate and 5-50 parts by weight of sintering aid; manganic acid The chemical formula for strontium la...
Embodiment 1
[0054] (1) Disperse 100 parts by weight of LTCC glass powder in 60 parts by weight of organic additives (ethanol, xylene, polyvinyl butyral, and polyethylene glycol in a volume ratio of 10:10:1:1) to form Apply the ceramic slurry; then cast a ceramic film with a thickness of 0.5um, dry it at 60°C and punch it, then remove the glue at 850°C for 2 hours, and then sinter at 1650°C for 2 hours to obtain the upper ceramic green body; Via holes are cut on the ceramic green body to obtain the first layer.
[0055] (2) Disperse 100 parts by weight of alumina powder in 60 parts by weight of organic additives (ethanol, xylene, polyvinyl butyral, polyethylene glycol in a volume ratio of 10:10:1:1) to form medium ceramic slurry; then casting a ceramic film with a thickness of 0.5um, drying at 60°C and punching, and then debinding at 850°C for 2 hours to obtain a medium ceramic green body.
[0056] (3) 100 parts by weight of alumina, 15 parts by weight of strontium lanthanum manganate (La...
Embodiment 2
[0061] The same steps as in Example 1 were used to prepare the ceramic heat dissipation substrate S2 of this example, the difference being that:
[0062] In step (3), strontium lanthanum manganate (La x Sr 1-x MnO 3 , x=0.20) is used in an amount of 5 parts by weight.
