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

66 System Reference, January 2001

Possible 256 pin DUT boards for either the 512 pin

test head or the 1024 pin test head

Additionally to the 1024 pin and the 512 pin DUT board

you can have a 256 pin DUT board. The advantage of the

256 pin DUT board is that it is smaller and therefore cost

saving.

NOTE: Normally a 256 pin DUT board is for engineering

use. In case you want to use a 256 pin DUT board for

production, make sure that the handler is able to reach

the DUT since the DUT can’t be placed in the center of the

DUT interface in case of a 256 pin DUT board.

There are four possibilities of configuring a 256 pin DUT

board. You can decide for one of four quarters of the 1024

pin DUT board. Each quarter contains one of the upper

line groups illustrated in Figure 32 on page 65 and the

adjacent group of the bottom line.

On your 256 pin DUT board you can have either:

1. group 8 and group 3.

2. group 2 and group 1.

3. group 7 and group 4.

4. group 6 and group 5.

Your choice for one of the pairs of groups should depend

on the groups’ properties according to your requirements.

These properties as digital dominant, analog dominant,

and/or analog instrumentation are given through your

customized tester configuration. See “Test System Config-

uration” on page 70 for configuration aspects.

The first two of the above listed possibilities can either be

used on the 512 pin or the 1024 pin DUT interface. The

third and the fourth possibilities can only be used on the

1024 pin DUT interface.
