Safety Precautions
It is essential to practice safety precautions when working with any electrical or electronic
products. Following these safety precautions can help protect both you and the equipment
from injury and possible permanent damage.
Whether the ICs are installed on a printed circuit board or laying on a table, integrated cir-
cuit components can be damaged by electro-static discharge. Static charges can build up in
people to a potential of several thousand volts by simply walking across a room.
Protect integrated circuits by:
• Using a static free work place and wearing clothes that do not hold static charges
before handling any of the workstation’s PC boards.
• Unplugging the power supply before removing or installing a part.
• Touching sheet metal with your fingers before touching the printed circuit assem-
bly.
If the assembly is not going to be re-installed, place the assembly in an anti-static bag and
set it aside. Following these precautions extends the life of the computer products you
maintain.
