Experiment with paper electronics with this silver conductive ink pen that will let you draw traces! We like the make of this pen, it has a nice liquid silver ink that flows easily, and it works great. In just 3 minutes from opening the packaging, we made the image above, a coin cell holder with an LED. There are two 'tips' available - standard and micro. The microtip allows for finer control but is a little harder to use (because it doesn't deposit as much silver at once).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 size of 0.7 mm and will draw traces that average 1.5 mm in width. See the image above with a demonstration of the kind of traces you can draw with each of the lines (by someone with no practice :) We strongly suggest reading the excellent tutorial document written by the makers which discusses use, shelf life, safety, soldering, and more!Technical Details MSDS file for CW2200 silver ink pens ChemTronics has a nice writeup with tips on how to use these pens! https://elecena.pl/product/22713449/conductive-silver-ink-pen-micro-tip-cw2200mtp 2023-03-06 https://elecena.pl/product/22713449/conductive-silver-ink-pen-micro-tip-cw2200mtp 2023-12-27 https://elecena.pl/product/22713449/conductive-silver-ink-pen-micro-tip-cw2200mtp 2024-09-19 https://elecena.pl/product/22713449/conductive-silver-ink-pen-micro-tip-cw2200mtp 2024-11-29 https://elecena.pl/product/22713449/conductive-silver-ink-pen-micro-tip-cw2200mtp 2024-11-30 https://elecena.pl/product/22713449/conductive-silver-ink-pen-micro-tip-cw2200mtp 2025-04-09 https://elecena.pl/product/22713449/conductive-silver-ink-pen-micro-tip-cw2200mtp 2025-08-05 https://elecena.pl/product/22713449/conductive-silver-ink-pen-micro-tip-cw2200mtp 2025-11-28 https://elecena.pl/product/22713449/conductive-silver-ink-pen-micro-tip-cw2200mtp 2025-11-29 https://elecena.pl/product/22713449/conductive-silver-ink-pen-micro-tip-cw2200mtp 2026-01-26
