Chemtronics CW3700 CircuitWorks The Mighty Pen, Universal Cleaning Pen
Chemtronics CW3700 CircuitWorks The Mighty Pen — Universal Cleaning Pen
Note: Not for sale or use in California.
The CircuitWorks Mighty Pen is a precision spot-cleaning tool designed for electronics technicians and PCB rework professionals. Its marker-style tip delivers controlled, exact application of a powerful fast-evaporating solvent — removing ink stains, label adhesives, conformal coating residues, and other stubborn soils without flooding the board or requiring additional tools. The mild citrus-based solvent provides low surface tension for superior wetting and quick evaporation with no secondary cleanup.

Frequently Asked Questions
What does the CW3700 Mighty Pen remove?
It removes ink stains, label adhesives, conformal coating residues, and most difficult-to-remove soils from PCBs and electronic equipment surfaces. The fast-evaporating solvent leaves no secondary residue requiring cleanup.
Is the CW3700 safe for use on PCB components?
The Mighty Pen is designed for precision spot application. Apply only to the target soil area and avoid prolonged contact with plastic housings or sensitive component markings. Test on a small area first when working with unfamiliar substrates.
Why can't the CW3700 be sold in California?
The solvent formulation contains VOCs that do not comply with California Air Resources Board (CARB) regulations. It is available for purchase and use outside of California.
How do I activate the Mighty Pen applicator?
Press the marker tip firmly against the surface to activate solvent flow. Apply with light strokes to the soiled area and allow to evaporate. For heavy soils, repeat as needed.
Can the CW3700 be used to remove conformal coating for rework?
Yes — spot removal of conformal coating is one of the primary applications. Apply the pen tip directly to the coated area and work the solvent in with gentle pressure. Follow up with a swab or brush to remove softened coating before it re-hardens.
