Different devices have different levels of sensitivity to electrostatic discharge, or ESD. Thus, there needs to be a way to distinguish ESD-sensitive devices from those which are not as vulnerable to ESD. Each of the ESD models used in ESD sensitivity testing has its own classification system for categorizing devices according to their ESD sensitivity.
Sensitivitas ESD perangkat biasanya ditentukan dalam hal tegangan uji ESD tertinggi yang dilewatinya dan tegangan uji ESD terendah yang gagal per model ESD. Dengan demikian, sensitivitas ESD sering dinyatakan sebagai rentang tegangan ESD yang dapat dikenakan perangkat dengan aman untuk setiap model ESD. Tabel berikut menyajikan tingkat klasifikasi sensitivitas ESD yang ditentukan oleh Asosiasi ESD untuk setiap model ESD.
Tabel 1. Klasifikasi Sensitivitas Komponen ESDS - Model Tubuh Manusia
(Per ESD STM5.1-1998)
Tabel 2. Klasifikasi Sensitivitas Komponen ESDS - Model Mesin
(Per ESD STM5.2-1999)
Tabel 3. Klasifikasi Sensitivitas Komponen ESDS - Model Perangkat yang Diisi Daya
(Per ESD STM5.3.1-1999)
A complete ESD characterization of every new product prior to its release is highly recommended. Complete ESD characterization consists of subjecting the device to ESD testing for all of the three ESD models, i.e., HBM, CDM, MM. Data for one ESD model can not be substituted for those of the other ESD models, since good ESDS test results for one model doesn't necessarily mean that the test results will also be good for the other ESD models. Thus, a company that takes its ESD program seriously must equip itself with ESD tester(s) capable of performing the required ESD tests for each of the test models.
