Has any been measuring the actual trace widths produced with toner transfer? I would think that running it through a laminator would significantly spread the trace. I just ordered a stage calibrator to measure widths with my microscope, but I would be very interested in hearing from anyone who had made these measurements. Mark

I think this is more critical than pressure.

Mark, Where did you order the stage calibrator? I need to get a calibrator and a reticle for one of my eye piece for my B&L. Craig --- In Homebrew_PCBs@yahoogroups.com, Mark Lerman <mlerman@...> wrote:

Craig, Ebay, from a company named TaxiMarket . Search under stage calibrator - there are loads of them listed. Mark At 04:35 PM 3/25/2010, you wrote:

If your traces are 10 mil wide and they spread by a mil or so on each side, you might not notice. But that same spread is very noticeable with 7 mil traces. Mark At 11:37 AM 3/25/2010, you wrote:

I can't find the recent post where I talked about this (I guess the search function is not yet working right??), but have a look at this test board that I did -- the patterns are 10/10, 8/8, 6/6, and 5/5. As you can see, after etching, the traces are not wider than the spaces; if anything, they are narrower. http://home.earthlink.net/~a_wake/tt_test_closeup.jpg --- In Homebrew_PCBs@yahoogroups.com, Mark Lerman <mlerman@...> wrote:

Here is some data on trace measurements with TT, http://www.artemlive.com/cgi-bin/news?c=v&id=751 About halfway down the page. Baxter --- In Homebrew_PCBs@yahoogroups.com, Mark Lerman <mlerman@...> wrote:
