What does conductive pen do?

Conductive ink pens are specialized writing tools designed to draw circuits and create electrical connections on various surfaces. The ink used in these pens contains conductive materials (e.g. silver), which allow it to conduct electricity.

Here's what a conductive pen can do:

• Circuit Prototyping: Conductive pens are often used for rapid prototyping of electronic circuits. Instead of traditional methods like soldering, engineers can draw circuit traces directly onto a PCB using the conductive pen.
• Repairs: These pens are useful for repairing damaged or broken circuit traces on electronic devices or printed circuit boards (PCBs). By drawing a new conductive trace with the pen, one can restore the electrical connection without requiring complex rework.
• Low-voltage Electronics: Conductive pens are suitable for low-voltage applications, such as wearable electronics, simple sensors, touch-sensitive interfaces, and other electronic projects that don't involve high power or high-frequency signals.
