Technical Data Sheet
TDS # CW2200
CircuitWorks Conductive Pen
PRODUCT DESCRIPTION
CircuitWorks
Conductive Pen makes
instant highly conductive silver traces on
circuit boards.
CW2200 is used in
prototype, rework, and repair of circuit
boards by linking components, repairing
defective traces, and making smooth
jumpers. The silver traces dry in minutes
and have excellent adhesion to most
electronic materials.
Engineers, repair
technicians, and manufacturers will find that
the CircuitWorks
Conductive Pen speeds
project completion and cuts rework time.
Single component system
High electrical conductivity
Fast drying
Highly adherent to circuit boards

COMPATIBILITY
CircuitWorks
Conductive Pen material has
excellent compatibility with materials used
in printed circuit board fabrication. As with
any chemical system, compatibility with the
substrate must be determined on a non-
critical area prior to use.
USAGE INSTRUCTIONS
Read MSDS carefully prior to use.
Cleaning:
For best adhesion, clean board with one
of Chemtronics Electro-Wash
or Pow-R-Wash
solvents in order to remove any surface
contamination which may prevent adequate material
contact.
Mixing:
Although this system has been formulated
to resist hard-packing, it should be shaken
vigorously for 30 seconds to insure the proper
dispersion of the silver flakes. If pen has been
allowed to sit idle for a long period of time, the
mixing ball may seize in the barrel. To free the ball
use force to tap the barrel end of the pen until the
ball begins to move inside the pen.
Application:
The conductive ink is dispensed
through the CircuitWorks
Conductive Pen.
Squeezing the pen body while pressing down on the
surface will allow the material to flow, enabling the
trace to be drawn. Practice with the pen before
attempting detail work. The bulk form of this
material may be applied by brushing, banding, or
automatic dispensing equipment.
Thinning:
The conductive ink has been optimized
for the CircuitWorks
Conductive Pen and thinning
is not normally necessary. However, Butyl Acetate
may be added with thorough mixing to make slight
adjustments for ease of application in the bulk form.
Clean-up/Removal:
The conductive ink may be
cleaned or removed using a strong organic solvent
such as Chemtronics
Electro-Wash
PX.
Curing:
Tack-free in 3 to 5 minutes at room
temperature.
Achieves electrical conductivity
within 30 minutes. Heat cure for 5 minutes at 250
to 300°F (120 to 150°C) for maximum conductivity,
durability and chemical resistance.
Soldering:
Low temperature soldering is possible
to the
heat-cured
silver conductive traces if done at
350°F (177°C) for <5 seconds.
