deform the board a xed amount as shown in Figure 15.
The exure #1 represents no displacement, exure #2 is
concave movement, exure #3 is relaxation to no displace-
ment and nally, exure #4 is a convex movement. This
motion is repeated for a number of cycles and the relative
output deviation is noted. The result shown in Figure 16a
is for two LT1460S8-2.5s mounted vertically and Figure
16b is for two LT1460S8-2.5s mounted horizontally. The
parts oriented in Figure 16a impart less stress into the
package because stress is absorbed in the leads. Figures
16a and 16b show the deviation to be between 125V and

250V and implies a 50ppm and 100ppm change respec-
tively. This corresponds to a 13- to 14-bit system and is
not a problem for most 10- to 12-bit systems unless the
system has a calibration. In this case, as with temperature
hysteresis, this low level can be important and even more
careful techniques are required.
The most effective technique to improve PC board stress
is to cut slots in the board around the reference to serve
as a strain relief. These slots can be cut on three sides of
the reference and the leads can exit on the fourth side. This
“tongue” of PC board material can be oriented in the long
direction of the board to further reduce stress transferred
to the reference.
The results of slotting the PC boards of Figures 16a and
16b are shown in Figures 17a and 17b. In this example
the slots can improve the output shift from about 100ppm
to nearly zero.
