How Do We Eliminate ESD?
To eliminate ESD
with "bead blasting" technology
requires a total system design
concept. True ESD elimination
cannot be achieved by adapting an off-the-shelf metal
de-burring machine.
CCRCo's Workstations
are statically controlled to insure the
protection of components on printed circuit boards during the
conformal coating removal process. We do this by:
Using a state-of the-art, in-line,
air/nitrogen ionizer with tungsten emitters and auto-balancing. This
ionizer is incorporated into our workstations, which decreases the need for
calibration to approximately four years
(vs. monthly with standard ionizer bars).
Combining the auto-balanced ionizer with our
specially designed nozzle, feeding ionized air into the media stream
just before it leaves the nozzle, thus
eliminating any ESD charge that
has built up in the media chamber.
Formulating a special thermo-set acrylic
plastic media to be as ESD safe as technically possible. When our
media is mixed with ionized air you get typical
ESD readings in the single digits.
Designing our workstations to take ionized air
and send it through a manifold just above the arm holes in the front
of the unit.
This floods the entire work chamber with
ionized air, eliminating any possible static buildup, and
neutralizing the ambient air that might enter the work chamber. This
ensures that all elements in the
work chamber (i.e. inside
surfaces, nozzle, viewing hood, lights, gloves, media, printed
circuit board and operator) are free
of an ESD charge.
Fitting the work chamber with a
conductive mat
attached to an external post located on the
front of the unit, providing a connection point for a wrist strap.
Constructing the workstation cabinet with ESD
conductive laminate. The laminate, media chamber, static resistant
mat, and operator are all connected together. An external terminal
is supplied on the side of the unit for connection to your house
equipment ground. Doing this guarantees that
all work area surfaces are static free.
Including a ground monitoring system that
constantly monitors to see if the operator, workstation, and your
house ground are all connected.
If the circuit is broken, you will receive an
audible beep and flashing red LED.
Including a built-in
ESD voltage meter
(CCR2000
workstations only). This is connected
to the inside of the work chamber and attached by clip to your
printed circuit board, directly reading the ESD voltage being
generated (as the conformal coating is removed).
CCRCo
is the only manufacturer with the
confidence to supply you with true ESD readings!
By building in these features,
CCRCo guarantees you will generate ESD voltage levels far below the
requirements set by private industry—or any US Government Agency.
Why take a chance and ruin
hundreds–if not thousands–of dollars worth of product?
CCRCo is clearly the only choice for true ESD safe conformal
coating removal.
