For ESD sensitive (ESDS) components you must identify the sensitivity of the
components on the reel, and on surrounding reels on the machine.
EIA-625 states"Essential materials/items, during normal / intended use,
shall not cause stsatic voltages greater than +/- 200 volts to be within
twelve (12) inches of unprotected ESDS devices.
What is your electrical failure rate on these components after placement?.
You may not have a problem if you don't experience a large fall out in
electrical test and your failure analysis does not indicate ESD as the
failure cause. Latent failures may be indicatd by a higher than expected
return rate due to failure of ESDS components. This failure should also be
verified by failure analysis.
