How to Use a Chemtronics Conductive Pen for Quick PCB Repairs
Key Takeaways
- Chemtronics conductive pens deliver quick, precise PCB trace repairs using silver-based ink
- Surface prep with isopropyl alcohol ensures strong adhesion and reliable conductivity
- Quick-drying formula allows immediate testing and is ideal for on-site or bench-top rework
For electronics technicians and engineers, printed circuit board (PCB) damage is an inevitable challenge. Whether caused by wear, improper handling, or rework errors, a broken trace can halt progress. Fortunately, the Chemtronics conductive pen offers a fast, reliable solution for restoring conductivity without soldering or complex repair equipment.
This precision tool dispenses silver-based conductive ink through a fine-tip applicator, allowing users to "draw" new traces or reconnect broken ones directly on the board. To use it, simply shake the pen, prime the tip by pressing it down, and apply the ink over the damaged trace. The ink dries quickly — typically within minutes at room temperature — forming a conductive path that’s ready for testing or immediate use.
The Chemtronics conductive pen is ideal for repairing broken traces, creating jumpers, or modifying circuit layouts during prototyping. It's especially useful in field service or cleanroom environments where speed and portability are essential. For best results, ensure the repair area is clean and free of oils or oxidation — using isopropyl alcohol is highly recommended. Applying the ink in thin, even layers improve precision and conductivity.
Among its benefits, the conductive pen enables rapid repairs with minimal equipment. It’s easy to store, portable, and requires no heat, making it safer for delicate components. However, it's not suited for high-current repairs, and careful surface prep is necessary to ensure proper adhesion.
