Quantic Croven's cold weld sealed quartz crystal resonators ensure hermetic seals without heat, offering cleaner welds, enhanced crystal aging, and improved phase noise for high-precision applications.

Precision quartz crystals must operate reliably for many years under sometimes adverse conditions including large ambient temperature variations and exposure to moisture and other environmental contaminants.

This white paper explores the application of pressure correction to Residual Gas Analysis (RGA) test results for vacuum-sealed quartz resonators. RGA testing, crucial for assessing hermeticity and preventing device failure, is discussed with a focus on moisture concentration. The paper introduces the amendment of MIL-STD-883 M1018 for pressure correction and provides insights into estimating internal pressure and applying correction factors. The importance of correcting data for low package sealing pressure is emphasized for accurate evaluation of device reliability.
