ESD Activities

Definitions:

ESD : ElectroStatic Discharge
HBM : (Human Body Model) An electrostatic discharge(ESD) event meeting the waveform criteria specified in standards, approximating the discharge from the fingertip of a typical human being to a grounded device
MM : (Machine Model) An electrostatic discharge (ESD) used to simulate an event occurring from a low resistance source
CDM : (Charge Device Model) An electrostatic discharge (ESD) used to simulate the actual discharge event that occurs when a charged device is quickly discharged to another object at a lower electrostatic potential through a single pin or terminal
EPA : ESD Protected Areas
ESD tester : Equipment that applies a HBM ESD (Thermo Keytek Zapmaster MK.2 SE) or a CDM ESD (Thermo Scientific Orion3) to a component

Human Body Model (HBM) & Machine Model (MM)
	*SERMA Main Strength on HBM & MM tests* Fast turn around (standard within 1 week) Qualification & Characterization Test standards: MIL, Jedec, ESDA, AEC-Q100 Devices up to 512 channels (upgradeable up to 768) Range HBM 8kV, MM 2kV Static curve trace (5 power supplies) IV curves tracing after each stress Strong IV curves analyser tools
Human Body Model (HBM)	*Systems Strengths ?* IC & discrete devices High IC device pin count test capability Automatic and repeatable tests Weekly waveform verifications Model ? HBM represents the discharge from the fingertip of a standing individual delivered to the device MM represents a discharge from any tool or production equipment to the device	Machine Model (MM)

Charged Device Model (CDM)

	*SERMA Main Strength on CDM tests* Fast turn around (standard within 1 week) Qualification & Characterization Test standards: Jedec, ESDA, AEC-Q100 Range CDM 2kV Test on 0.2mm pitch components Automatic hygrometry control 11GHz scope available (waveform verification at 6GHz) Static curve tracing (with HBM tester)

	Model ? CDM simulates the charging or discharging of an IC through a single pin to a conductive surface, resulting in a fast-rising, high current stress.
