suitable pens for etching boards

[toneless]

Pen Test:
Pilot Silver  
Staedtler Lumocolor
edding 142
edding 140s
Artline 853
edding 792 Silver paint marker
Pilot Twin marker

I've tryed those pens and here are my results:
All permanent markers will work very good as long as you make two coats and let them completely dry for a long time...

The best pens were Edding 792 and Artline 853.
The first one is a silver paint marker(it has paint in it!!!) and the
second one is a overhead projection marker.

Hope this helps.

Good job, thanks for sharing info we all need sooner or later

I have made few small pcbs with nail polish and enamel paint many years ago, but it was painful experience if you made a mistake. Sharp pointed toothpic worked well as paintbrush

Do you think one of these would work well then:

Well,i think this pen will do the job with only one apply!!!
Just let it dry for a few hours...or when you are going to etch the next pcb just write your name on the copper to try it...

I've heard that pens for cars will do the job,too.
JD Sleep suggest pens from craft or fabric stores that have paint in them but i haven't found those yet.

Check your local office supply store!

They now have "Industrial" Sharpies.  It says right on them that they're designed to resist chemicals, etc.  One pass on your board, let dry for about 30 seconds and throw it in the etch - perfect traces everytime!
