Alumina Ceramics:
Double-layer Alumina Ceramic Substrate refers to copper with double-sided and metallized holes, that is, copper with double-sided, and copper in the hole.For the double-sided ceramic substrate, copper in the hole is particularly important. Because the earliest and most difficult is the presence of copper in the hole (how to have copper on the wall of the hole without copper), this is the most important basis for distinguishing double-sided and single-sided. However, the fake double-sided panel, only has copper on both sides, but the hole There is really no copper in it, so it is said that there is no copper in the holes, but the ceramic substrate with holes on both sides is called a fake double panel. It looks like a double panel. There is a difference between the actual and double-sided alumina ceramic substrate. There are wiring on both sides of the board, but to use the wires on both sides, you must have a proper circuit connection between the two sides. This "bridge" between circuits is called a via. The pilot hole is a small hole filled or coated with metal on the pcb, and it can be connected to the wires on both sides. Because the area of the double-sided board is double that of the single-sided board, the double-sided board solves the difficulty of wiring interleaving in the single-sided board (which can be conducted to the other side through the hole), and it is more suitable for more complicated circuits than the single-sided board. Advantages (compared with single-layer boards): Convenient wiring, concise, less wiring labor intensity, shorter circuit length. The use of autorouters to design ceramic substrates is attractive. In most cases, automatic wiring will not cause problems with purely digital circuits (especially low-frequency signals and low-density circuits). However, when you try to use the automatic routing tools provided by the routing software to do analog, mixed-signal, or high-speed circuit routing, some problems may occur, and they may cause extremely serious circuit performance problems.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
