17-1 Measuring Pin Margins

Overview

To get reliable results while testing your devices on the production 

floor, you must use tester settings that take into consideration the 

margins caused by tester and device.

The pin margin tool can measure the margins of your Device-Under-

Test (DUT) on a pin by pin base or on a group base. These margins are 

normally measured by a passing functional test of the testflow. The pin 

margin test measures the minimum lower and upper margin of the pins 

or pin groups.

The main purpose of the pin margin test is to ensure that you have 

enough headroom with your tester to test correctly the current device 

in a volume production on multiple test sites. In some cases the pin 

margin test can also be used to find a single hardware resource (edge 

or level) that can be moved to make a failing device pass.

N O T E

The margins can only be measured if the functional test with the actual 

settings passes. Only if you suspect a certain pin or pin group to cause 

the fail result it might be reasonable to use a failing setting to identify 

this pin or pin group.

A good way to find critical hardware resources is to determine the 

margins of pin groups first to detect the groups where critical pins are 

located. In a second step the margins of group members of those groups 

can be measured to identify critical pins. In a last step the margins of 

edges and levels of these selected pins can be measured. This ‘Top-

Down approach’ reduces the length of the test report and the test time.

The pin margin test does not characterize your DUT. To characterize 

the DUT you should use other tools like the Shmoo Tool or the test 

functions.

The pin margin test characterizes the tester and the test program. It 

helps you to find suitable tester settings for your production test envi-

ronment. In this way you will avoid failing devices unnecessarily.
