DUT Board Mechanical Considerations 4 Test Head Filling and DUT Board Considerations

System Reference, January 2001

Make sure that your 256 pin DUT board possibility is

located in that area of the DUT interface where the pogo

pins of your pair of groups come out.

Warning: Locating the 256 pin DUT board on the pogo pin

area of two different groups for which it was not designed

you will have to reconfigure your pins and very likely will

have to change your card cage filling which may be impos-

sible because of your tester configuration.

Figure 33 A Pair of Pad Blocks (No. 228)

In Figure 33 on page 67 the two horizontal boxes are such

a pair of pad blocks. The dots inside the boxes represent

the pads. One pad block consists of 16 signal pads which

connect to the 16 pins on a digital board or an analog

module. Each of these signal pads is surrounded by three

or four ground pads. This leads to three pads in a column

and 8 signal pads in the two middle rows of a block. A 17th
