Ceramic substrate species:
1, alumina substrate:
a. Raw material: A1203 raw material typical manufacturing method is Buyer method, in this method, in this method, the original material is used in aluminum aluminum (aluminum mine / one water soft aluminum stone and corresponding compound);
b. Method: A1203 ceramic forming generally uses a laminated layer method, and the adhesive 1 is used to use a polyvinyl alcohol polymethylene (PVB) number, and the firing temperature varies depending on the added bunner. 1550 ~ 1600c. The metalization method of the A1203 substrate is currently mainly using thick membrane methods and co-burning methods. It is more mature from the slurry used to process technology, and can meet the requirements of various aspects;
c. Application: Substrate for mixed integrated circuit, LSI package substrate, multilayer circuit board
