Direct Bonded Copper (DBC) High Power Performance Matching Thermal Coefficient of Expansion (TCE)

Directly Bonded Copper Applications

Break-thru in packaging high power copper bonding semiconductor die

DBC Advantages for your Power Designs:

  • Allows higher power distribution area
  • The TCE match with silicon is improved
  • Superior heat sinking dissipation (a lower thermal resistance)
  • Excellent conductivity
  • Good mechanical strength
  • Environmentally clean
  • Excellent electrical insulation (25 kv over 1 minute)

Heat sinking with thru-hole connections

How to use DBC for High Power Performance:

  • “Chip-on-board” technology (allows tighter packaging of modules, thus providing greater design flexibility)
  • Motor controls applications
  • Semiconductor and hybrid semiconductors.
  • Various types of control circuits.

Imagine the possibilities of using direct Cu bonding for your application.
