Static Discharge Causes Flaky Damage
By Stephen Bucaro
Some time ago I purchased a motherboard, CPU, and memory from a
local computer store. The sales person did me the "favor" of
plugging the CPU and memory into the motherboard. I held my
breath as this was done with no care whatsoever taken to prevent
damage from a possible electrostatic discharge.
A static discharge can damage or destroy integrated circuit
electronics. The problem is that you may not see a visible
spark. You may not know that a static discharge occurred. And,
you are lucky if the static discharge totally destroyed the
circuit.
Often a component is only damaged and appears to work. This type
of damage can produce occasional or frequent errors. This is
what technicians call "flaky" because the failure does not occur
reliably enough to be able to track it down.
The technician can't determine if the errors are caused by
software or hardware. All they can do is keep changing things
and waiting to see if the problem goes away. This is very time
consuming and costly.
The proper way to handle computer circuits is to wear a grounded
wrist strap. Any electrical charge that builds up on your body
is then immediately conducted to ground. But experienced
technicians have tricks for controlling static electricity.
One trick is to leave the circuit board laying on top of an
antistatic bag or antistatic foam as much as possible. Another
is to leave the computer plugged into the AC outlet with the
computers power switch off. This places ground on the computers
metal case. Then the technician works with one hand always on a
metal part of the case. Any electrical charge that builds up on
your body is then immediately conducted to ground the same as
with a wrist strap.
The important thing is to take static discharge seriously. Don't
stick yourself or someone else with a flaky computer because you
were too lazy to take basic care to protect against static
discharge.
