The technical advancement in the electronic and semiconductor
industry places increased demands on the materials currently
in use today. One concern and major talking point facing this
industry is the problem of electrostatic discharges more commonly
known as ESD.
Electrostatic charges occur while abraising surfaces (tribo
electric). During this process the following happens, a loss
of electrons on the supplying surface(positive charge) and
a gain of electrons on the receiving surface (negative charge).
One result of this action is the attraction of dust particles,
with effects such as untiding wafers. Uncontrolled static
discharges lead to degradations on the circuits and contacts
of semiconductor devices.
Due to the extreme damage ESD can cause to semiconductor devices during the
production process, there is an absolute necessity to use only materials, which
by their nature exclude electrostatic discharges.
In addition we have seen an increasing requirement to reduce
the particle numbers in clean room areas. This also places
limitations on the materials that can be used.
A solution to overcome these problems is the use of ESLON
DC Plates(DC=dust clean). ESLON DC Plates have a conductive
surface coating both sides. The surface resistivity is Ohm
and is considered as being in the static dissipative range
of antistatic products.
ESLON DC Plates are available in three base materials: PVC,
PMMA/Acrylic and Polycarbonate. As a matter of course the
conductive coating does not influence the excellent clarity
of the base material nor does it detract from each materials
advantageous technical characteristics(fabrication ability,
low weight and impact resistance).
ESLON DC Plates can be supplied in transparent colours which
are "clear", "smoked-brown", "orange"and
"yellow". For applications with frequent chemical
contact and or high abuse a "Hard Coat"version of
the above products are available.
Typical applications for ESLON DC Plates include ESD safe
machine covers, various kinds of clean room glazing, ESD work
stations, microelectronics and test equipment for circuit
boards.
