Aerospace Data Acquisition System

Nuvation Engineering designed and manufactured a 24-channel data acquisition system for a client in the aerospace industry. The design uses mainly COTS components, specifically selected for their radiation tolerant attributes. In addition to the design of the product, Nuvation Engineering developed and was responsible for the full IPC Class-3 manufacturing process, including: PCB assembly, AOI, X-ray, flying probe testing, epoxy staking, conformal coating, chassis assembly to controlled torques, chassis staking, many rounds of functional testing, and 40-hour HASS test.
