Страница: 3 / 29

Electronic components and circuits are sensitive to
ElectroStatic Discharge (ESD). When handling any
circuit board assemblies including Leetop Tech COM
Express carrier assemblies, it is recommended that
ESD safety precautions be observed. ESD safe best
practices include, but are not limited to: • Leaving
circuit boards in their antistatic packaging until
they
are ready to be installed. • Using a grounded wrist
strap when handling circuit boards, at a minimum
you should touch a grounded metal object to
dissipate any static charge that may be present on
you. • Only handling circuit boards in ESD safe areas,
which may include ESD floor and table mats, wrist
strap stations and ESD safe lab coats. • Avoiding
handling circuit boards in carpeted areas. • Try to
handle the board by the edges, avoiding contact
with components.
