ADVANCED ANALYSIS / TEST

CDM

CDM (Charged Device Model)

  • This test is considered to be the most closely related mechanism to field defects. Use the method of charging and discharging the charge in the package, and the CDM classification level is from 200V to 1000V.
  • 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.
