Space Level Capabilities

DDC has more than 30 years of experience in the design and manufacture of hybrids for space applications. This includes supplying MIL-STD-1553, motion feedback, and motor drive and controller hybrids for use on launch vehicles, satellites, deep space applications, and the International Space Station. In satisfying customers’ needs to achieve the highest levels of reliability. DDC is fully qualified to build, test and qualify our hybrid circuits in accordance with MIL-PRF-38534 for all classes including class K.

DDC can also screen to specific profiles, enabling customers to choose from a menu including element evaluation, particle impact noise detection (PIND) testing, 320 hour burn-in, 100% nondestructive wire bond pull, and/or radiographic (X-ray) analysis. Additionally, DDC Microelectronics, formerly Maxwell Technologies, offers radiation mitigation RAD-PAK® Technology. RAD-PAK® enables DDC to deliver reduced cost space grade solutions providing total dose immunity of 100 krads or higher utilizing standard commercial chips. RAD-PAK-based solutions have been qualified for use by NASA.
