usage of antistatic solution in areas to control the generation of static charges

The use of antistatic chemicals (antistats) may be a supplemental part of an overall organized ESD program.

Any antistatic chemical application must be considered as a means to reduce or eliminate static charge

generation on nonconductive materials in the manufacturing or storage areas.

The application of any antistatic chemical in a clean room of class 10,000 or less cannot be permitted.

Accordingly, any user of antistatic solutions must consider the following precautions:

D Antistatic spray or solutions in any form cannot be applied to energized electrical parts, assemblies, panels,

or equipment.

D Antistatic chemical applications cannot be performed in any area when bare chips, raw parts, packages,

and/or personnel are exposed to spray mists and evaporation vapors.

The need for initial application and frequency of reapplication can be established only through routing

electrostatic voltage measurements using an electrostatic voltmeter. The following durability schedule is a

reasonable expectation.

D Soft surfaces (carpet, fabric seats, foam padding, etc.): each six months or after cleaning, by spraying.

D Hard abused surfaces (floor, table tops, tools, etc.): each week (or day for heavy use) and after cleaning,

by wiping or mopping.

D Hard unabused surfaces (cabinets, walls, fixtures, etc.): each six months or annually and after cleaning,

by wiping or spraying.

D Company-furnished and maintained clothing and smocks: after each cleaning, by spraying or adding

antistatic concentrate to final rinse water when cleaned.

The use of antistatic chemicals, their application, and compliance with all appropriate specifications,

precautions, and requirements must be the responsibility of the area supervisor where antistatic chemicals are

used.
