4 Test Head Filling and DUT Board Considerations Wafer Prober DUT Board and Probe Card

110 System Reference, January 2001

17th signal lines on the probe

card

In Figure 33 on page 67, additionally, a 17th signal line is

illustrated. Four of the eight 17th signal lines of a group

each are also available on a probe card segment. They are

placed in the smaller lightly shaded grey area on the left

side of the white area. Table 22 shows the numbers of the

pairs of pogo pad blocks the four 17th signal lines connect

to within the groups.

Table 22 Pogo Pad Block Assignment of the 17th Signal Lines of the

Segments on the Groups of the Packaged Parts DUT Board

If the signal lines connect to the block of the analog pogo

pads or to the digital pogo pad block of one pair of pogo

pad blocks (see “Pad Blocks” on page 67), depends on

your customized wafer prober DUT board and heavily on

your test head configuration (see “Test System Configura-

tion” on page 70).

NOTE Within one segment you can only have digital or analog

signal lines since there is only one ground (either digital or

analog). (If you are using the standard SOC wafer prober

DUT board, (E7018AA or E7018AB), all signal lines

connect to the digital pogo pad blocks.

utility line pogo pads on the

probe card

The white area of Figure 48 on page 108 contains the

pogo pads of the utility lines. The functions of the pogo

pads numbered from U01 to U20 are listed in Table 23 for

the 512 pin probe card and in Table 24 for the 1024 pin

probe card.
