To the group Most might know this but to correct scratches and other imperfections on TT I use a paint pen. I went to Hobby Lobby and got a Tree House Studio #564815 fine tip Paint-Marker and it works better than any thing I have used. I am sure any hobby place would have what you need. I think any brand with fine tip would work. Derward Myrick KD5WWI [Non-text portions of this message have been removed]

Is that something like a Sharpie? I've been using Sharpies for a while now, they are available in what they call a "Fine Tip" and an "Ultra Fine tip". If the Tree House is different, I will have to try one. Thanks for sharing. Ken H. --- In Homebrew_PCBs@yahoogroups.com, "Derward Myrick" <wdmyrick@...> wrote:

I bought an "extra fine point etch pen" from All Electronics. It turns out to be a sharpie, but industrial variety, "super permanent ink" with a chemical resistant label. Supposed to resist most chemicals and up to 500 Degrees F. Sharpie #13801. It was sold by Datak. No idea of how good it is. I'll be finding out in a week or two. Harvey

Ken, This is real paint and comes in all collors. I think there are many brands of paint pens. The paint is very resistant to the etch solution. I used red because you can see it very easy. When you ask for paint pen they know what you want. Derward Myrick KD5WWI

The problem with the paint pens is that they don't keep so well. If you are a hoarder like me you'll sooner rather than later be left with a box of useless hard pens. That seems to happen much faster with the "laquer" variety where you must pump the tip and hear a steel ball inside when shaken, the permanent marker variety seems to store much better. One pen that works well on most etchants is the staedtler lumocolor permanent marker. The red color is best (the ink is also used in the marker for chemical lab glassware). <http://www.staedtler.co.za/upload/318_2_420_16611.jpg> It only resists strong etchants without fail if the pen is fairly fresh, so it is best to get the refill station so you always have a "new" pen at low cost.

Dear Stefan Trethan it may have already been mentioned (my apologies if that is so!), but Edding permanent markers can be "reloaded", do not seem to dry out quickly and at least in black resisted all etchants that I have used. I used them years ago to touch up both foils for PCBs and final PCBs before etching. (though not for some years.) I have only used black though for etching, I could not say if the other colors work as well in that respect, but they also do not dry out quickly as long as the cap is properly on....I have a set that I have had for at least 5 years of all the colors......they are still good though only used occasionally....all are reloadable if you buy the refill bottles....I have only reloaded black myself though. They also come in several thicknesses too.

(Apologies if this is a double-mail, my last attempt seems to have disappeared) I've been meaning to ask re Sharpies: I got one, but the results are not great. The first TT project I saw, the author signed the PCB with a Sharpie and the result was clearly visible post-etch. But for me, I lose maybe 50%. (not that I want to sign my every board, but as a touch up tool, I have to cross my fingers) Is there a secret with Sharpies (cure time, cure process?) Or is the US formulation using chemicals banned elsewhere in the world or something? Anyway, the Staedtler sounds rather promising .... (re the thickness, mine would be ca. 30 mil. Not thin, but much more limiting is my ability to draw accurately, and the tip is round so you're never quite sure which part is going to touch down first) PG On Tue, Jan 5, 2010 at 4:39 AM, Lee Studley <indigo_red@...> wrote: > > > What was the line width achieved with this pen. thanks -Lee > > __________ Information from ESET Smart Security, version of virus signature > database 4743 (20100104) __________ > > The message was checked by ESET Smart Security. > > http://www.eset.com > > > [Non-text portions of this message have been removed]

I have to go over the sharpie spot two or three times to get good coverage. The first "marking" will not be totally dark, but by the 3 or 4th time marking over the same spot it seems to work pretty good. I've used both the fine point and Ultra fine point - the fine point is NOT what I would consider a fine point, more of a blunt point - 30 mil would be with a new sharp "fine" point.

Yes, Edding markers are of the slow drying kind. I have not found any with tips as fine as the Staedtler pens. ST On Mon, Jan 4, 2010 at 6:54 PM, Andrew Mathison <andrewdavid.mathison@...> wrote:

Dear Piers Goodhew
see my previous post on Edding pens, they come from fine upwards!

Dear Stefan Trethan
if you need it so fine then buy a fountain pen (cheapest you can buy, kids quality) and load it up with Edding ink from a refill bottle, or just dip the nib into the ink and clean well afterwards!!!
This idea has NOT been tried by me personally!!!
Regards
Andy

You could, but the staedtler pen wih a ruler to guide it is good for 10mil lines or so, and I'm just too darn lazy to do much masking up. Once the process was dialled in I didn't need much correcting anyway. ST On Wed, Jan 6, 2010 at 12:53 AM, Kerry Wentworth <kwentworth@...> wrote:
