At present, the classification of ceramic substrates is divided into aluminum oxide ceramic substrates and aluminum nitride ceramic substrates according to the plate; DPC ceramic substrates, COB ceramic substrates, BDC ceramic substrates, etc. according to the process, then what is the difference between DPC ceramic substrates and BDC ceramic substrates? ?
First look at what is a DPC ceramic substrate, what is a BDC ceramic substrate
These two kinds of boards are mainly named because of different processes. DPC ceramic substrate adopts DPC-magnetron sputtering + electroplating process with high precision and high equipment cost; DBC process - copper is directly sintered to ceramic board, direct printing - The thick film process equipment is cheap, the process is mature, but the precision is not high. The alumina ceramic manufacturing method has a casting method dry pressing gel.

Second, it is the difference and difference between the two processes.

DPC ceramic

DBC skills. The copper layer is thick, the processing is fast, the price is cheap, and it can be made into multiple layers, which is suitable for large-area consumption.
However, this skill cannot pass through the hole, the precision is poor, and the flatness (appearance roughness) is low. Appropriate devices can not be used in precision occupations on products with large spacing. Nowadays people's life and death levels are getting higher and higher, and the quality of products is getting higher and higher.
DPC Skills This technique uses copper sputtering to perform copper plating. This process is one step ahead of other processes. Its strength lies in its high precision. Good flatness, good separation force (within the scope of application), can pass through the hole.
The drawback is that this skill can only be made into thin sheets (thickness <300μm), and its cost is high, production is limited, and the time of frequent shipments cannot be on time.
In addition, there are other skills and crafts in the market. Jinruixin Special Circuit is a professional ceramic circuit board proofing and mass consumer manufacturer. It can complete DPC, DBC, solid copper filling, 3D process and dam technology.
