The changes in issue 4 of ESCC 3503 (CRYSTAL CONTROLLED OSCILLATORS) are included in the DCR 1349 and detailed herein below:
During the LAT, the constant acceleration test has been considered too stressful, cumulating Random vibrations, Mechanical Shocks and Constant Acceleration. The assembly’s verification is made by the acceleration test performed during the screening; no need to make it twice.
Furthermore, this test is not representative of the product’s environment during its product lifetime.
NOTE: The implementation of the above changes will induce a modification of the detail specification ESCC3503/001 in case DCR dated 19/06/2020 is implemented before this one.
