DIRECT BOND COPPER SUBSTRATES

Prototype to Medium Volume Solutions

Remtec now offers cost effective and fast turnaround Direct Bond Copper (DBC) products on Alumina and Aluminum Nitride. Direct Bond Copper is a widely acceptable and a timeproven technology for power electronic products due to its high thermal conductivity, high current capacity and heat dissipation of the high-purity copper on ceramic. By varying copper and ceramic thickness and ceramic type one can affect a resulting CTE value of total system to avoid a CTE mismatch with different semiconductor devices. The addition of optional dimple features incorporated into your design greatly increases thermal cycling reliability by reducing thermally induced stress and effectively increasing reliability after thermal cycling.

To meet the growing demands of today’s competitive marketplace Remtec utilizes the well-known quality of DBC ceramics coupled with high quality Remtec® plating typical for its PCTF® technology. A combination of both results in a unique, quick turnaround solution fulfilling a need for prototypes to medium volume DBC substrates.

In addition, versatile copper finish options ensure an excellent solderability and capability to withstand multiple soldering and brazing operations in a wide temperature range of 180 to 800oC, without any degradation in product integrity and reliability. Ni-Au and Pd plating finish enable a broad range of economical assembly techniques: SMT soldering, low and high temperature die attach, Al and gold wire  and ribbon bonding.

Our LVM (low volume manufacturing) Direct Bond Copper program will be available for orders that may not meet the minimum requirements for a normal production run with other manufacturers. LVM orders may be limited to select material configurations and quantities; please contact your sales representative for more information.
