HBM

    HBM (Human Body Model)

    • A test that assumes that two objects in the state of losing or obtaining an electric charge are "semiconductor" and "body". Construct a circuit that simulates human characteristics and apply an ESD pulse to the semiconductor. The HBM classification level ranges from 250 V to 8000 V.
    • ESD is one of the main causes of defects in semiconductor products, and it is a phenomenon in which electric charges move instantaneously as two objects with different potentials come into contact. The human body gains or loses electric charges in a number of ways, which are commonly known as friction electricity, and then becomes positive or negative. The various situations in which semiconductor devices experience actual ESD phenomena have been modeled, and the ESD resistance of the product is classified into several grades according to each test level.

    • The HBM qualification test is carried out at the following levels/skipping voltage levels are not allowed
    • 500V, 1000V, 2000V.
    • If a fault is observed at 500V, carry out an HBM test at 250V. If a fault is observed at 250V, carry out an HBM test at 125V.
    • If the unit fails at 250V and a tester meeting the waveform requirements at 125V is not available, the part is class 0A
    • (i.e., < 125V) shall be classified.
