Product Description

Metallized Ceramic Componenets:

Innovacera supplies precision metallized ceramic parts in aluminum oxide ceramics for the aerospace industries. Through spray, needle, and brush coatings or screen printing our capabilities allow us to metallized on flat, cylindrical, and complex ceramic bodies. Moly-Manganese is the typical base coat materials used for metallization.In order to achieve the welding between ceramic and metal, the ceramic surface firmly adheres to a layer of the metal film, which is ceramic metallization.Refractory-metalized aluminum oxide ceramics widely use in power grid tubes, vacuum interrupters, and similar applications where metal to ceramic joints of exceptional strength and hermeticity is required.

Types of Metallization Ceramic Substrates

 

DBC (Direct Bonded Copper)

It is composed of ceramic substrate, bonding bonding layer and conductive layer. It refers to the special process of copper foil directly bonding to alumina or aluminum nitride ceramic substrate surface at high temperature.

 

Advantages: >The copper layer is thick; >The processing is fast; >The price is cheap; >Can make multilayer; >Suitable for large area consumption; >High thermal conductivity; >High adhesion strength; >Excellent soft brazing; >Excellent electrical insulation

 

DPC (Direct Plated Copper)

Mainly by evaporation, magnetron sputtering and other surface deposition process to carry on the substrate surface metallization, first under the condition of vacuum sputtering, titanium, and then is copper particles, the plating thickness, then finish making line with ordinary PCB craft, and then to plating/electroless deposition way to increase the thickness of the line, the preparation of DPC way contains vacuum coating, wet deposition,Exposure development, etching and other processes.

 

Advantages: > In terms of shape processing, DPC ceramic plate needs to be cut by laser, the traditional drilling and milling machine and punch machine can not be accurately processed, so the combination force and line width is also more fine. > The crystal performance of the metal is good; > The flatness is good; > The line is not easy to fall off; > The line position is more accurate, the line distance is smaller, reliable and stable, can be through the hole and other advantages.

 

AMB(Active Metal Brazing)

It is a method to realize the bonding of ceramic and metal by reacting a small amount of active elements Ti and Zr in filler metal with ceramics to form a reaction layer which can be wetted by liquid filler metal.

 

Advantages: The combination is achieved by chemical reaction between ceramic and active metal solder paste at high temperature, so its bonding strength is higher and reliability is better
 

 

Thick film ceramic substrate

Thick film technology, it is straight on ceramic substrate printed graphics, then direct sintering process.

 

Advantages: > The bonding force with ceramic is much greater than that of the DPC process; > It is direct printing of graphics,no etching and copper plating process, so the cost will be lower; > It is one-time forming, so the flatness is smoother than that of the DPC.
