Caneta de Tinta Condutora - Circuit Scribe

• Circuit scribe conductive ink pen
• Can be used on any surface
• Can draw 60-200 meters

The Circuit Scribe Conductive Ink Pen can draw 60-200 meters depending on writing surface and speed. 60 meters is seen on absorbent surfaces similar to a napkin, and 200+ meters on photo paper. Photo paper also has other benefits: you can erase ink by scratching a trace away, and you also get the highest conductivity on this surface (<2 ohms/cm). Soldering to the ink is possible - but tricky - and greatly depends on paper/surface type and solder type.
