Safety Precautions
CAUTION: 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 circuit 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
assembly.
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.
