T-Global's TG-CPCB series are thin film direct bonded ceramic substrates (DC-CPCBS). A copper surface is chemically bonded to the ceramic and then chemically etched to form the desired electrical circuit. A thin layer of gold is deposited onto this for circuit quality control and to prevent oxidation. This produces excellent thermal management and removes many of the reliability issues associated with IMS type solutions. TG-CPCB boards can also come supplied with a pre-attached thermal tape for easy heatsink attachments.
