DFM is Done -- Now For Corrections and Peer Feedback

Good morning everyone!  

     I returned the last batch of DFM reports last night.  For those of you that missed one, or all, opportunities, fear not -- Royal does DFMs dozens of times a day.  If there is sufficient interest, I can organize another opportunity for the class.

     This week you should work on fixing any issues that came up in your design.  I forgot about the July 4th holiday -- so let's plan on submitting your files for fabrication by/on end-of-day Tuesday the 7th.  I'll email participants missing file requests Wednesday and we'll hopefully order the boards on Thursday.  You will need to include a Bill-of-Materials for your design.  The barest minimum of information in a BOM follows:

As a reminder, the software just looks for the most critical number in each design.  As long as you stay above the process minimums for the fab-house you plan to use, you'll be fine.  And now that you know what to look for -- take a moment to update your Design Rules.  Remember, even though there are all sorts of features that are checked, you can base most numbers off of the trace/space minimums for your fab-house (be sure to include a margin-for-error).

Trace and Space guidelines

Consider sharing your design files in the forums.  Participants can view Gerber files with online tools such as http://mayhewlabs.com/3dpcb or free software such as KiCad's GerbView.  Gerbers have been around for a while, so there are plenty of other options out there -- share the ones you like in the forums!

Have a great day everyone!
