CLASS 3A
CLASS 3B
Procedures (HBM)
For every pin, a positive and negative pulse is applied between (1) the pin and ground, (2)
the pin and VCC, and (3) the pin and all other pins tied together.
Test
Electrostatic Discharge (ESD)
Conditions
Purpose
Failure
Human Body Model (HBM) JESD22-A114
To establish the ESD sensitivity.
A failure is any device that fails to meet data sheet electrical requirements after ESD testing.
Goal is >1000V on all I/O Pins (HBM)
Pass/Fail
a. JESD22-A114 is used as reference.
