Direct Bond Copper Substrates

Remtec Product

Proven, Cost-Effective Technology Gets Products to Market Faster.

Remtec now offers Direct Bond Copper (DBC) products on alumina and aluminum nitride, typically coupled with our high-quality Plated Copper on Thick Film (PCTF®) plating technology. This powerful combination enables us to develop unique solutions to meet a variety of needs.

Direct Bond Copper is a widely accepted and proven technology for DC power electronics products. By varying copper and ceramic thickness and ceramic type, our DBC substrates achieve a CTE value of the total system to avoid a CTE mismatch with different semiconductor devices.

Remtec’s state-of-the-art equipment and manufacturing processes allow us to deliver DBC substrates—from prototype up to medium-volume production runs—with a fast turnaround. We even offer a low-volume program for small orders other manufacturers won’t touch (see below).


  • High-purity copper on ceramic provides superior levels of thermal conductivity, current capacity and heat dissipation.
  • Optional dimple features significantly increase thermal cycling reliability by reducing thermally-induced stress.
  • Versatile copper finish options ensure an excellent solderability, able to withstand multiple soldering and brazing operations from 180–800°C, without any degradation in product integrity and reliability.
  • Ni-Au and Pd plating finishes enable a broad range of economical assembly techniques, including SMT soldering, low- and high-temperature die attach, Al and gold wire, and ribbon bonding.
  • Our (DBC) Direct Bond Copper program is available for orders that may not meet the minimum requirements for a normal production run with other manufacturers.*
