Ready-For-Transfer Printed Circuit Board Layout

[Grizz]

How do you decide what size to make these if the designer doesn't give dimensions? Do you assume the size on the screen is the proper size and print as is?

thanks,

I print them out on regular paper and place an IC or IC socket over any IC pads on the layout, just to confirm.  Sometimes, even when they ARE laid out to scale, they be printed out NOT-to-scale in a myriad of silly ways (e.g., your print settings within Acrobat), so it is nice to confirm scale before committing to photpaper, PnP, or worse - copper.

Thanks...That's a good idea.

As someone who has to use Acrobat often for work, there's ordinarily a default setting in the print options that scales the document size to fit withing the printer's bleed area (the space at the edges of a page the printer can't print on) thus making things not print to the expected scale.  If you make sure that's unchecked it will print 1:1.
