Compensation and Measurement: Open and short
compensations are recommended before measurement.
Short compensation is performed by bringing down the
shorting plate (which is already on the fixture) to short all
4 terminals. Open compensation is performed by bringing
down both the open plate and the shorting plate to
separate the high terminals from the low terminals. After
performing open and short compensations, the DUT is
inserted into the test fixture. The figures below show how
compensation and measurement are performed.
Diameter of probe pin is 0.19 mm
Diameter of Blade electrode’s contact spot is 0.5 mm
Spacing between Blade electrode and probe pin is 0.11 mm
SMD can be between 1.6 and 8.0 mm in width
