Product Description

Dbc/Dpc Ceramic Heat Sink Metallized Alumina Ceramic Substrate with Copper/Au Coating

DBC alumina ceramic substrate DPC ceramic substrate metallized ceramic heat sink copper coated ceramic board gold plated ceramic substrate power electronics packaging ceramic circuit substrate custom ceramic substrate

Product Description

96 percent alumina ceramic brings matched electrical thermal and mechanical properties for high power electronic working conditions. It maintains high dielectric strength to isolate high voltage circuits and prevent breakdown during continuous operation. The ceramic material offers reliable thermal conductivity to transfer heat from active chips to external cooling structures. DBC thick copper layer delivers high current carrying capacity suitable for heavy load power modules. DPC thin film gold or copper coating achieves finer circuit resolution for compact high density electronic assemblies. The metallized interface forms stable bonding with ceramic base and resists delamination under repeated thermal cycling. Dense ceramic microstructure has low moisture absorption so insulation performance remains stable under changing humidity environments. All metallization and machining parameters can be adjusted to fit different semiconductor packaging and thermal management designs.

Feature 

*96 percent alumina ceramic base provides high voltage insulation and steady heat dissipation performance 
*Selectable copper or gold coating to satisfy high current or anti corrosion fine circuit requirements 
*Strong metal ceramic bonding interface reduces peeling risk during repeated thermal cycling 
*DBC supports thick copper layer for high current load DPC enables ultra fine circuit patterning 
*Customizable ceramic dimension metal thickness circuit pattern and edge processing
Application 
Metallized ceramic heat sink substrate for IGBT SiC GaN power semiconductor modules
