In Figure 31you can see which of the card cages of the 512

pin test head match which of the groups on the 512 pin

DUT board. NOTE that the numbers of the groups have

nothing in common with the numbers of the card cages.

Figure 31 1. Allocation of the 512 pin DUT board’s groups to the card cages

of the 512 pin test head. 2. Numbering of pairs of pad blocks.

On the left side of Figure 31, for example, you can see that

group 8 matches with card cage 2.As previously

mentioned, the smaller light boxes on the DUT board illus-

tration are called half groups. Each half group contains

four pairs of so called pad blocks. A pad block is the

landing area of a pogo pin block on the DUT board’s pads.

The numbers in the illustrated half groups are each

assigned to one pair of pad blocks. For the description of a

pair of pad blocks see “Pad Blocks” on page 67. NOTE:

The correlation of the pairs of pad blocks to the affiliated

slots in the card cages is shown by the slot numbers next

to the half groups.
