( Precaution when repairing ESD )
n
There is ESD which is easily damaged by
electrostatics.(for example Integrated circuit,
FET ) Electrostatic damage rate of product
will be reduced by the following technics
n
Before handling semiconductor
parts/assembly, must remove positive
electric by ground connection, or must wear
the antistatic wrist-belt and ring. ( It must be
operated after removing dust on it – It
comes under precaution of electric shock.)
n
After removing ESD assembly, put on it with
aluminum stuff on the conductive surface to
prevent charging.
n
Do not use chemical stuff using Freon. It
generates positive electric that can damage
ESD.
n
Must use a soldering device for ground-tip
when soldering or de-soldering ESD.
n
Must use anti-static solder removal device.
Most removal device do not have antistatic
which can charge a enough positive electric
enough damaging ESD.
n
Before removeing the protective material
from the lead of a new ESD, bring the
protective material into contact with the
chassis or assembly that the ESD is to be
installed on.
n
When handing an unpacked ESD for
replacement, do not move around too much.
Moving (legs on the carpet, for example)
generates enough electrostatic to damage
the ESD.
n
Do not take a new ESD from the protective
case until the ESD is ready to be installed.
Most ESD have a lead, which is easily
short-circuited by conductive materials
(such as conductive foam and aluminum)
