The CW2200 Conductive Pens: Tips and Tricks for Best Performance
The CircuitWorks Conductive Pens, part numbers CW2200STP and CW2200MTP, areamong Chemtronics most popular products. These pens have a wide range of uses,from drawing traces between components on proto-type circuit boards, coating components and assemblies to shield them from electrical and radio frequency interference, to repairing broken solder traces on PCBs and broken grid lines on automobile rear-windshield defoggers. The silver-filled acrylic polymer in the CW2200 pens provides a quick, easy alternative to building solder traces between components
and can effect repairs where conventional soldering techniques are not practical or possible. The nature of the conductive “ink” does lead to issues with regard to shelflife, flexibility, clogging, conductivity, curing and thinning which I would like to address in this article.Tip Assembly and Trace Dimensions
The tip of the CW2200 Conductive Pens is really a spring-loaded retractable stopper.
As you press the tip of the pen against a hard surface, the tip retracts into the tipassembly, opening a channel through which the conductive ink flows out of the pen.
Ejection of the ink is aided by gently squeezing the flexible pen barrel. The CW2200STP (standard tip pen) has an orifice size of 1 mm and will draw traces
that will average 2.0 mm in width. The CW2200MTP (micro-tip pen) has an orifice sizeof 0.7 mm and will draw traces that average 1.5 mm in width. A skilled technician, with
experience in using the CW2200 pen applicators should be able to produce consistent
traces that will be narrower than the dimensions cited. If even narrower trace widths
are required, the ink can be applied using a fine artist’s brush or pen. A stencil can also
be prepared to facilitate the drawing of fine pitch traces. The CW2200 Conductive Ink
is also available in bulk form in a 100 gram bottle for large-volume brush or pen
Shelf-Life and Clogging
The unopened CW2200 Conductive Ink Pens have a shelf-life of 18 months from its
date of manufacture. The four-digit manufacturing date code appears on a sticker
affixed to the back of the product display/instruction card. This code is read as follows:
the first digit indicates the year of manufacture (4 = 2004, 5 = 2005, etc.); the nextthree digits indicate the consecutive day, from 001 to 365, on which the product wasmade. After this time ITW Chemtronics can no longer guarantee the performance of
