Subject: Re: [Homebrew_PCBs] Re: more experiments with Toner transfer by etching the boards first

Hi,

I did some experiments with toner from brother and hp lasers. The mixes did not work at all, so I tried to soak  the toner image ( on normal paper) in pure ACETONE ( high yield nail polisher remover ) and hardly touched the toner. The HP was reacting the a bit and made the solution a bit black, but the brother toner did not butches.

Now my only thing I can do is using more pure ACETONE instead of the nail polish remover.

I do this experiments in a basement at slightly less then room temperature.

OK just a note, today I made my first 2 sides board using toner transfer and it came out great the holes lined up perfectly.


But after I finished etching the board I though I would try to cleaner the toner off with Acetone, the same Acetone I tried to do the cold transfer with the other day and to my shock I had to scrub like hell to get it off. 

So ether my toner is the wrong type for acetone transfer or the acetone is not so pure. Also another thing comes to mind, maybe it to cold. I'm doing it in the garage and it's cold out there so who knows maybe Acetone doesn't work so good when it's cold.  

In the past one wipe with Acetone and the toner was gone, but it was summer then.
