Each method has its pros and cons. Which method or combination of methods is best will be hotly debated in the years to come? The case study outlined here demonstrates the significant cost savings that can be realized when answering the question, “How rad hard do I need?” and when considering the use of commercially based parts.

Traditional radiation-hardened or “rad-hard” parts are generally considered to be capable of withstanding the most severe space environments. In fact, these devices are designed and fabricated with the specific goal of enduring the harshest space radiation environments.

Performing an environmental test means subjecting the device or system to certain environmental conditions (cold, dry heat, relative humidity, etc.) in order to check if the operational parameters remain within the range defined by the applicable regulations.

Tests, inspections or combination thereof, imposed on 100% of parts to remove unsatisfactory items or those likely to exhibit early failures. Using stress testing, defects are weeded out in a product where the root causes cannot be eliminated. Removing all the defective parts (infant mortality) brings the lot to the constant failure rate (working life) phase. The screening does not increase the reliability of the components but removes those showing weakness or defects. Tests, inspections or combination thereof, imposed on 100% of parts to remove unsatisfactory items or those likely to exhibit early failures.

The general specification for hybrid microcircuits (MIL-PRF-38534) details the qualification and testing requirements for non-hermetic packages for military and space applications, and the MIL-PRF-38535 proposed class Y monolithic microcircuits for non-hermetic space level.

NewSpace is an approach that focuses on lowering the barriers to entry to space industry, by providing cheaper access to space… One of the major characteristics of the NewSpace era is the fundamental shift from an industry which was heavily dependent on government agencies to a more agile and an independent private sector that relies on innovation, working with much smaller budgets than the early space industry.
