JEDEC has just revised JESD625, “Requirements for Handling Electrostatic-Discharge-Sensitive (ESDS) Devices,” and the new Revision B is now available for purchase from Document Center Inc. in either paper or pdf format. The new 31 page JESD 625 replaces the previous JESD625a from December 1999.
The passage of a static charge through an electrostatic-discharge-sensitive (ESDS) device can result in catastrophic failure or performance degradation of the part. This standard establishes the minimum requirements for Electrostatic Discharge (ESD) control methods and materials used to protect electronic devices that are susceptible to damage or degradation from electrostatic discharge (ESD).
Device sensitivity to ESD is determined by test methods for Human-Body Model (ANSI/ESDA-JEDEC JS-001, “Joint Standard for Electrostatic Discharge Sensitivity Testing – Human Body Model (HBM) – Component Level”) and Charged-Device Model (JESD22-C101 ”Field-Induced Charged-Device Model Test Method for Electrostatic Discharge Withstand Thresholds of Microelectronic Components”). ESDS devices with HBM or CDM sensitivities of less than ±200 volts may need additional protective measures beyond those specified in this standard.
The device types for which these requirements are applicable include, but are not limited to, ESD sensitive discrete and integrated circuit semiconductors, multi-chip modules, optoelectronic devices, and thin film passive devices.
JESD 625b is directed at two user groups:
Semiconductor Manufacturers – from wafer electrical probe through shipment of finished devices. However, the requirements of this standard are not imposed prior to probe. Prior to probe, the manufacturer should take appropriate ESD precautions to minimize damage to devices.
Semiconductor Processing/Testing Facilities – from receipt through shipment of finished devices. ESDS Device Distributors and users may use this standard or ANSI/ESD S20.20 ”Protection of Electrical and Electronic Parts, Assemblies and Equipment (Excluding Electrically Initiated Explosive Devices).”
All ESDS devices shall be handled in accordance with this document until they are considered scrap.
For your convenience, JEDEC has included a two page Annex B with information on the differences between JESD 625a and JESD 625b.
