5.3 Test Conditions. Unless otherwise stated herein, inspections are performed in accordance with

those specified in MIL-PRF-55310 and MIL-PRF-38534, in that order. Process travelers

identify the applicable methods, conditions and procedures to be used. Examples of electrical

test procedures that correspond to MIL-PRF-55310 requirements are shown in Table 3.

5.4 Special Tests and Descriptions.

5.4.1

Frequency-Temperature Slew. Frequency-Temperature Slew Test has been developed as an

indicator of higher than normal internal water vapor content. The incremental temperature

sweep from +125°C to -55°C and back to +125°C records output frequency fluctuations

emulating the mass loading of moisture deposited on the crystal blank surface. Though not

replacing a customer’s internal water-vapor content (RGA) requirement, confidence is

increased without destructively testing otherwise good devices.

5.4.2

Burn-in Delta Frequency Aging (in Option D). The frequency measurement for burn-in delta

measurements is performed at the crystal’s upper turning point temperature where its effects on

repeatable frequency accuracy are maximized. Dependent on the crystal specified, this

temperature is typically between +65°C and +85°C, ±0.2°C.

5.5 Deliverable Data. The manufacturer supplies the following data, as a minimum, with each lot

of devices:

a. Completed assembly and screening lot travelers, including rework history.

b. Electrical test variables data, identified by unique serial number.

c. Frequency-Temperature Slew plots, Radiographic films, Group C data and RGA data as

required by purchase order.
