Sine Vibration Random Vibration Shock Acceleration Altitude Radiation Electrostatic Discharge Sensitivity 3.3 MIL-STD-202, Method 204, TC “D” MIL-STD-202, Method 214 TC “I-K” (15 minutes per axis) MIL-STD-202, Method 213, TC “F” MIL-STD-883, Method 2001, TC “A” 50,000 feet minimum to deep space Radiation testing is not performed, but these VCXOs have been acceptable for use in environments up to 100K rads by analysis of the components used. Only bipolar semiconductors are employed.
3.3.1 All piece parts shall be derived from lots that meet the element evaluation requirements of MIL-PRF38534, Class K, with the following exceptions: Active Elements a) Visual inspection of silicon on sapphire microcircuits. Semicircular crack(s) or multiple adjacent cracks, not in the active area, starting and terminating at the edge of the die are acceptable.
3.6.2. Technical Data Package - When required by the purchase order, the following design documentation and information is deliverable 30 days prior to the start of production. The Technical Data Package shall consist of the following: a) Assembly drawing(s). b) All electrical schematics and drawings not considered proprietary. c) The assembly and screening travelers to be used on-line to manufacture the devices supplied to this specification. d) Parts and materials list. 3.
