Hi!
I saw the comment abot the HP Presentaion paper. So I went to staples yesterday and bought a package!
I took a board design and printed it on this paper and I am very happy with the results! It was easy to iron on in only about three or four minutes,and a soak of ten minutes in water and the paper was fairly easy to remove.I will try the Vinegar on my next ry in a day or two!
I will make a test pattern to see how thin a trace I can make with it.I got a decent line down to 15 mils so far.Using a iron..
Thanks for the info
Mike T

The Staples paper is OK, but not great - It takes a LOT of work to get all the paper off. One that works much better is HP Presentation paper Q2546A - http://www.staples com/office/ supplies/ StaplesProductDi splay?storeId= 10001&jspStoreDi r=Staples& productId= 156882&cmSearchK eyword=q2546a& fromUrl=home& cmArea=SEARCH& catalogId= 10051&langId= -1
This requires less pressure and heat than the Glossy Photo paper - I assume this is because of the lower thermal mass? - and comes off very cleanly.
A neat trick to help remove the paper: instead of soaking in water, soak the PCB+paper in ordinary white vinegar. The longer you leave it, the easier it is to remove, but about 10 minutes in room-temperature vinegar works great. Then a quick wipe with your thumb or a paper towel dipped in the vinegar and all the glue/coating comes right off.
