IEC 61340-5-3, “Electrostatics – Part 5-3: Protection of electronic devices from electrostatic phenomena – Properties and requirements classification for packaging intended for electrostatic discharge sensitive devices,” has just been revised. The new Edition 2.0 is available from Document Center Inc. now. It updates the Edition 1.0 from 2010 which has become obsolete.
The standard defines the ESD protective packaging properties needed for electrostatic discharge sensitive devices (ESDS) during those products’ life-cycles. The test methods you’ll need to use for this are referenced in the standard and performance limits are also provided.
Of course, if you use the IEC 61340-5-3, you’ll want to know what the changes are in this new edition. First of all, the reference to ANSI/ESD STM11.13 (“Two Point Resistance Measurement”) have been removed and replaced by references to IEC 61340-4-10 (“Electrostatics – Part 4-10: Standard test methods for specific applications – Two-point resistance measurement”). This IEC publication was taken directly from the 2004 Edition of the ANSI/ESD document.
You’ll recognize the ANSI/ESD standard as a publication from the EOS/ESD Association here in the U.S. If you use the ANSI/ESD STM11.13, you’ll want to know that there is a new 2015 Edition available. Since the 2015 Edition replaces the 2004 Edition adopted by the IEC publication, we may see an update of the IEC 61340-4-10 document as well.
Secondly, the Edition 2.0 of the IEC 61340-5-3 has additional notes for Table 1 and the addition of a new Table 3. This new Table 3 is related to the ESD classification symbol and the primary function code. It’s a 3 column table. The first colum is the primary function code itself, the second column defines the primary function the code references, and the 3rd column is the ESD classification symbol. It’s a useful addition to this publication.
