liquid impregnating the plastic is eventually used up after which the bag is as 
useless for preventing damage from ESD as any ordinary plastic bag. 

Anti-Static bags made of plastic impregnated with metal (usually silvery in color) 
provide all of the charge equalizing abilities of the pink-poly bags but also, when 
properly sealed, create a Faraday cage that completely isolates the contents from 
discharges and the inductive transfer of static charges. 

Storage bins made of plastic impregnated with carbon (usually black in color) are 
also excellent at dissipating static charges and isolating their contents from field 
effects and discharges. 

  Never use ordinary plastic adhesive tape near an ESD sensitive device or close to 

an anti-ESD bag.  The act of pulling a piece of standard plastic adhesive tape, such 
as Scotch

®

 tape,  from its roll will generate a static charge of several thousand or even 

tens of thousands of volts on the tape itself and an associated field effect that can 
discharge through or be induced upon items up to a foot away. 

This section provides guidance for working properly at either the instrument rack or the 
bench, including transferring components back and forth between the two. Also presented 
are instructions for properly opening shipments and unpacking, and for packing and 
sealing components for shipping 

When working on the analyzer while it is in the instrument rack and plugged into a 
properly grounded power supply. 

1.  Attach your anti-ESD wrist strap to ground before doing anything else. 

  Use a wrist strap terminated with an alligator clip and attach it to a bare metal portion 

of the instrument chassis.  This will safely connect you to the same ground level to 
which the instrument and all of its components are connected. 

2.  Pause for a second or two to allow any static charges to bleed away. 

3.  Open the casing of the analyzer and begin work.  Up to this point, the closed metal 

casing of your analyzer has isolated the components and assemblies inside from any 
conducted or induced static charges. 

4.  If you must remove a component from the instrument, do not lay it down on a non-

ESD preventative surface where static charges may lie in wait. 

5.  Only disconnect your wrist strap after you have finished work and closed the case of 

the analyzer.
