| How is a unit tested for HBM ESD? How many zaps should a unit get? Are the zaps on all pins done at the same time? What's a good reference on HBM ESD test procedure?

| master zapper,
# of zaps depends on the pin configuration of the device. more power supplies, more zaps, because every pin should be zapped against each unique power pin. every i/o pin must also be zapped against all other i/o's tied together. btw, zaps should be done twice - one negative pulse + one positive pulse. to give you an idea, an 8-lead op amp may get >30 zaps for hbm testing. reference? try this: JEDEC JESD22-A114. the man |
