Feature request: Eurocircuits Technology Class upload

chipdesk — Sun, 21 Oct 2018 12:03:23 GMT

Each time I start the design of a new board, I have to set the DRC-rules. I base them on the Technology Class from Eurocircuits (my preferred manufacturer for prototype boards):

One nasty pitfall is the selection of the right Drill Class. I've already experienced that selecting a "smallest final hole" of 0.25mm (Drill Class C in Eurocircuits) actually requires a drill of 0.35mm (within the Eagle DRC-rules). That's because after drilling, the metallization procedure deposits a thin layer of 0.05mm, resulting in a diameter shrink of 0.1mm (2 x 0.05).

So this is what I need to select in Eagle:

This is just one nasty pitfall when manually entering the DRC-rules in Eagle. I can imagine many more things can go wrong. Therefore, I believe it would be a nice feature if one could somehow "load" the Eurocircuits Technology Class into the Eagle DRC-rules.

Once you've got your DRC rules set up once, you can SAVE them to a file yourself. If you're feeling generous, you can share that file with others.

Hi @chipdesk,

I hope you're doing well. @one-of-the-robs is spot on, that's probably the best solution. You may want to check out the Design Rules > Examples that ship with EAGLE. We have a lot of rule sets from Eurocircuits maybe the one you need is already there. That will save you the work of making the DRU file yourself.

Let me know if there's anything else I can do for you.

Best Regards,
