grounded conditions (minimum of once a week)

A visual inspection must be made to determine full compliance with this specification at static-free workstations

during handling of static-sensitive items, including operator being grounded as required, static-sensitive items

not being handled in unprotected or unauthorized areas, and no static-generating materials at the grounded

workstation.

sleeve protectors (minimum of once a week)

A visual check must be made to determine that each operator wearing loose-fitting or long-sleeved clothing

either has sleeves properly rolled or covered with sleeve protectors and is properly grounded with a wrist strap

to the bare skin.

static voltage levels (minimum of once a week)

In addition to the visual inspections, a sample inspection using an electrostatic voltmeter to check for

uncontrolled electrostatic voltages at or near electrostatic-controlled workstations.

conductive floor tiles (minimum of once a month)

Conductive floors must have a resistance of not less than 100 k

Ω from any point on the tile to earth ground. Also,

resistance from any point-to-point on the tile floor three (3) feet apart must be not less than100 k

Ω. The test

methods to be used are ASTM-F-150-72 and NFPA 99.

records

Written records must be kept of all ESD QC audits.

training

Training is applicable for all areas where individuals come in contact with ESD-sensitive devices. It is the

responsibility of each area supervisor to make sure that his/her people receive ESD training initially and every

12 months thereafter to maintain proficiency. Training may include static fundamentals, a review of applicable

parts of this specification guideline, and actual applications in the work area.
