Identification and Status
To indicate the status of a drawing, a box with the
numbers 0 to 9 is shown in the bottom-right of the
drawing. The number that is crossed-out is the status
numberofthe drawing. For example, in the illustration
below, the status is 1.
A sticker is used on the units themselves to identify
them and to indicate their status. For example, in the
illustration below, the top line is the 12-digit number
that identifies the unit type.
The first four digits of the number on the second line
representadatecode(year,week);thenext four digits
represent the serial number for that week.
Thenumberinthegreyareaindicatesthestatusofthe
unit. The last two digits represent the number that will
be given to the next status. However, if these two
digits are contained in a box, then this is the current
status. For example, in the illustration above, the
current status of the unit is 01.
Line 1 392240700000
Line 2 123456AA0101
Line 3 VR/0123456789
Line 1
This is the code number of the printed circuit board
assembly (PCB).
Line 2
This is the serial number of the PCB. The first 6 digits
andthe2lettersareforinternaluse.Thelast four digits
reperesent the date of the manufacturing: wwyy.
Example:
123456AA1402 means the PCB is manufactured in
