Direct Bond Copper Substrates

Curamik® Electronics


DBC Substrate for Power MOS Module
Curamik® is the innovator in DBC technology. The company has been supplying DBC substrates to the world leaders in electronics since 1983. Capacity for high volume orders is supported with manufacturing facilities in both Germany and the U.S.

Curamik® produces DBC substrates with aluminum oxide and aluminum nitride. By having a complete in-house etching and plating facility (electroless nickel and gold), excellent quality control is maintained.

Curamik® Electronics is part of the Bowthorpe Thermal Management Group, with worldwide representation. This gives us the resources to supply and support DBC substrate requirements worldwide.

You can expect the following from us:

QUALITYAll substrates are manufactured in traceable lots with documentation of all materials and process parameters used.

Statistical process control throughout all major manufacturing steps and application related tests of wirebondability and solderability result in close to zero defect deliveries.

Thermal shock cycling and other reliability tests are carried out according to industrial, automotive and military standards.

We have preferred supplier status to most international power semiconductor and automotive electronics manufac-turers.

INNOVATION
  • Inventor of mastercard technology. A new design of multiple-up substrate arrays prevents masters from early separation during shipping, handling and processing.
  • Inventor of 3-dimensional substrates with integral leadoffs.
  • Inventor of divided ceramic substrates to prevent unnecessary bending of base plate.
  • Inventor of thin alumina DBC, a competitive alternative to toxic BeO and to advanced AlN substrates.
  • Inventor of lightweight liquid cooled DBC substrates for very high power dissipation.
  • Inventor of solid copper vias available in mastercard technology for high reliability front-to-back connections at reasonable cost.
PRICESIn the beginning, Curamik ® electronics did not have the luxury of defense contracts which would have made it possible to develop complex products in small quantities at high prices. Nor did we have the customers willing to run one product in huge quantities for several years without redesign. Instead, our customers asked for medium to high quantities with the possibility of flexible redesign without high tooling charges at competitive prices. Prestamping of copper and automatic single piece processing could not be considered. This is why we developed multiple-up master card processing. It gives us and our customers flexibility and cost advantages which cannot be achieved with any other production method. It results in the best quality available at the most competitive price worldwide.
PRODUCT BREADTHWe provide the widest range of DBC substrates on the world market:
  • Al 2O3 CurSTD ceramic .010”-.060” thick for industrial applications
  • Al 2O3 CurMIL ceramic .015”-.060” thick for automotive applications
  • Al 2O3 CurHP ceramic .010” and .015” thick for aircraft and defense applications
  • AlN CurSTD ceramic .025” thick for industrial applications
  • AlN CurMIL ceramic .025” for automotive, aircraft and defense applications
SUPPORTCuramik ® electronics is the only DBC manufacturer in the world which focuses all its efforts on DBC process-ing improving manufacturing efficiency. There is no distraction from the one goal of improving our product and our service for our customers.

This forms a unique concentration of know-how in our company which our customers can use: we can provide unique insight into how to improve a design in order to make it manufacturable for us and better functioning for our customers.

DELIVERYFast and flexible delivery has been one of our priorities from the beginning. Because fast deliveries are extremely important in samples and prototyping, our prototyping department is a separate operation within the company, with its own manufacturing equipment. This means that prototypes can be made within a few days if necessary.

Changing customer requirements are handled with very fast response times and short volume production turn-arounds. We have found that this is necessary to make you a satisfied customer.

CAPACITYCuramik ® electronics is the world’s largest independent DBC substrate manufacturer in terms of substrate area. Every year many million substrates are supplied to high volume users throughout the world. Besides the German plant, a new Dallas, Texas manufacturing facility was established to support our growth in America. This gives our customers two sources of high volume production.
