2.3.1.5 Outgassing ASTM E595 Compliance

The AFE7950-SP complies with the ASTM E595 standards for low outgassing. Outgassing tests were performed on five units in a vacuum below 5 × 10-5Torr for 24 hours at 125℃ . Materials were screened using total mass loss (TML) ≤ 1% and collected condensable material (CVCM) ≤ 0.1% thresholds.

Table 2-4 Outgas Test Results
Sample Material TML 1% CVCM < 0.1%
AFE7950ALKSHP Underfill PASS PASS
AFE7950ALKSHP Substrate PASS PASS
AFE7950ALKSHP TIM PASS PASS

This compliance minimizes the risk of contaminating sensitive optical or thermal surfaces within spacecraft, enhancing mission longevity and performance. Indeed, materials used in the AFE7950-SP are compliant.
