Use a grounded anti-static mat on your work bench (see below).
If you pick up a pc board that was not placed on an anti-static mat or in an anti-static package, touch
first a ground plane connection on the board such as a connector shell or mounting point.
If you use a soldering iron to work on a circuit board, be sure your iron has an ESD-safe grounded tip
tied to the same common ground used by your mat and wrist strap.
Choosing an Anti-Static Mat
An anti-static mat must bleed off any charge that comes in contact with it at a rate slow enough to avoid a shock
or short circuit hazard but fast enough to ensure dangerous charges cannot accumulate. Typically, a mat will
have a resistance of up to 1 Gigaohm (10
9
ohms). Testing a mat requires specialized equipment, so we
recommend that you choose an anti-static mat that comes with published resistance specifications and clean it as
recommended by the manufacturer. Testing has shown that many inexpensive mats that do not specify their
resistance have resistance values much too high to provide adequate protection, even after they were cleaned
and treated with special anti-static mat solutions.
Suitable anti-static table mats are available from many sources including:
U-line (Model 12743 specified at 10
7
ohms)
Desco (Model 66164, specified at 10
6
to 10
8
ohms)

Portable Service Kit (Model 8505 or 8507, specified at 10

to 10
9
ohms)
Tools Required
1. ESD Protection (see Preventing Electrostatic Discharge Damage, pg 1).
2. #1 size Phillips screwdrivers. To avoid damaging screws and nuts, a power screwdriver is not
recommended.
3. Soft cloth or clean, soft static dissipating pad to avoid scratching the enclosure.
