High Reliability Test (for aerospace application)

CDK has record of manufacturing for high reliability product which used for artificial satellite (space probe), Unmanned resupply spacecraft(HTV) for 40 years, and have been highly appreciated. In the case of spacecraft which returned a sample of material from a asteroid to Earth, we took part in assembly and evaluation of communication devices. We provide integrated operation service for high reliability products.
