Hi, I've never done laser printer transfers, but I've had some luck in the past printing to confirm footprint land patterns. I just did the print with the x and y scale adjusts as 1.00000. Intersting though, it seems like the default document is a different size than the letter paper I used. I'd try a dummy print first and hold some components on the paper to make sure everything makes sense.
One trick is to put a couple points at the corners of your board at a known distance. Than you can measure these "macro" dimensions to see if they print at the expected distance. If they're right, your "micro" dimensions (footprints) should be fine. Good luck, Louis On Thu, Nov 12, 2009 at 3:18 PM, hal8000b <[email protected]> wrote: > > > Apologies if this has been asked before. > > One way to make PCB's is to print the PCB template with a laser printer > onto acetate. > The acetate is then ironed to to plain copper clad PCB with a hot iron, the > ink transfers to the copper and when set board is ready to etch. > > My problem is, what viewing size gives actual size components? > In PCBnew the 3D viewer can show top view or bottom view (copper) and > then export as JPG or PNG image. > > Pressing F1 or F2 zooms in/out but I dont know which view ratio is actual > size, can anyone help? > After exporting the copper layer I can change it to black using Gimp but > its getting component, pads and track sizes correct. > > Thanks in advance. > > >
