Radiation

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. They are assembled

with all bipolar semiconductors with the exception of the ACMOS chip used for the

CMOS output which is purchased from a wafer that has been tested to a minimum of

100K rads total dose. A copy of the parts list and materials can be provided for review.

Manufacturing Information

QUARTZ CRYSTAL

For the ight models, swept quartz shall be used in the manufacture of the crystals. For the Engineering models, non-swept quartz

shall be used.

TRAVELLERS

Travellers or Process Cards are used in the manufacturing and testing of all of the 1794 Series VCXOs and are available for customer

review. Copies of these Travellers can be provided with the VCXOs at time of shipment if so speci ed on the purchase order.

TRACEABILITY and HOMOGENEOUS MATERIAL

Option Codes ‘S’ & ‘R’ only

Manufacturing lot and date code information shall be recorded, by VCXO serial number, of every component and all materials used in

the manufacture of that VCXO. Also all semiconductors used in the manufacture of any given Production Lot of VCXOs, shall be from

the wafer and have the same manufacturing lot date code. A Production Lot, as de ned by Vectron, is all oscillators that have been

kitted and assembled as a single group. After the initial kitting and assembly, this Production Lot may be divided into multiple sublots

to facilitate alignment and test capacity and may be sealed at multiple times within a 13 week window.

TEST DATA

All Test Data is recorded by VCXO serial number. Copies of this data can be provided with the VCXOs at time of shipment if so speci-

ed on the purchase order.

REWORK

All rework follows the requirements of Mil-PRF-55310 Class ‘S’ for Option Code ‘S’ and Class ‘B’ for Option Codes ‘R’, ‘B’ and ‘C’. The only

exception is the Select-At-Test components may be replaced up to four times.
