When the optional shunt resistance as specified in 3. The characteristics of this pre-pulse phenomenon depend on the conditions and the environment of the arcing associated with the HBM discharge, the parasitic capacitances of the tester, as well as the pin impedance of the device under test.

A voltage probe with a minimum input impedance of 10M? The tester must meet the requirements of Table 1 and Figure 2 at all voltage levels, except V, using the shorting wire and at the V and V levels with the ? This shunt kesd22 can be placed in the HBM simulator or in the test fixturing system.

ELECTROSTATIC DISCHARGE (ESD) SENSITIVITY TESTING HUMAN BODY MODEL (HBM)

Clarified that pin combination jsed22 may be partitioned as far as necessary and performed on different devices to eliminate possible cumulative effects. Example of proposed changes being utilized Test Flow 1 HBM testing will be done in adherence to Table 2, with selected pin combinations replaced by alternative pin combinations.

The number of power pins tested on Terminal A may be reduced if the power pin group is connected on a package plane see clause 4. Clarified power pin definitions.

If the Supply pins are connected on package plane clause 4. The objective is to provide reliable, repeatable HBM ESD test results so that accurate classifications can be performed. All pins one at time to Gnd2 power pin group 3.

Some punctuation changes are not included.

Due to this effect the current waveform seen at Terminal B would not match the one seen using a non-relay, 2-pin HBM test between the same set of pins. Due to this effect the current waveform seen at Terminal B would not match the one seen using a non-relay, 2-pin HBM test between the same set of pins. Clarified power pin definitions. Requirement, clause number Test method number Clause number The referenced clause number has proven to be: JEDEC standards and publications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for use by those other than JEDEC members, whether the standard is to be used either domestically or internationally.

This tester issue was found to divert significant current away from the pins connected to Terminal B, such that the slew-rate of the current at terminal B is lower than seen at Terminal A. This part of the slow decay shall be excluded in determining the trailing pulse magnitude. NOTE 2 Precautions must be taken in tester design to avoid recharge transients and multiple pulses.

If at any time the waveforms do not meet the requirements defined within Figure 2 and Table 1 at the V or V level, the testing shall be halted until the jeds22 is in compliance. All pins one at time to A114ff power pin group 4. When the optional shunt resistance as specified in 3.

Documents Flashcards Grammar checker. However, if a pin intended to supply power to a circuit on another jesdd22 but not to any circuit on the same chip, it may be treated as a signal pin. All pins one at time to Gnd1 power pin group 2. The tester-dependent voltage rise was observed to alter the timing of the protection action. Included pins connected to charge pump capacitors as power pins. Any pin that is intended nesd22 supply power to another circuit on the same chip must be treated as a power pin.

A Zener diode with breakdown voltage between 6 V and 15 V and a rating between? The objective is to provide reliable, repeatable HBM ESD test results so that accurate classifications can be performed. The V level is optional. The simulator must be capable of supplying pulses with the characteristics required kesd22 Figure 2 and Figure 3.

Some advanced technologies may be vulnerable to these pulses resulting in an electrical a114v EOS. Each non-supply pin to all other non-supply pin; all power pins left unconnected. HBM Test plan would as follows: Added third reference to table: All pins one at time to Gnd1 power pin group 2.

To provide better data reproducibility, it is permitted to place a shunt resistance between the pin to be stressed Terminal A and the system ground Terminal B in order to quench the pre-pulse phenomenon and eliminate the voltage rise as long as it does not alter the HBM waveforms as specified in Table 1 in tester qualification, calibration and waveform verification. The ESD test shall be performed at room temperature. If you can provide input, please complete this form and return to: JEDEC standards and publications are adopted without regard jed22 whether or not their adoption may involve patents or articles, materials, or processes.

All pins one at time to Gnd3 power pin group 4. In the test sequences where a14f power pin group is held at ground Terminal Bmesd22 is permitted to have all the pins in the group tied together and connected to Terminal B or to have only the previously selected pin s connected to Terminal B with all other pins in the group left floating. Additionally, the system diagnostics test as defined in 3.

Added in 4 language stating clearly that ESD testing must be performed on samples of the actual chip being evaluated In 4. It is recommended that the manufacturers supply the worst-case pin data with each DUT board.

If testing is required at multiple temperatures, testing shall be performed at the lowest temperature first. This issue may impact slew rate triggered ESD protection methods on higher pin count packages. If you can provide input, please complete this form and return to: Each non-supply pin to all other non-supply pin; all power pins left unconnected. All pins one at time to Vdd1 power pin group 5.
