[sdiy] PCB faceplate large hole creation?

[Brian Willoughby]

Do you folks use the DFM rules?

I use Eagle, and I have a DFM file for each fab house. Some fab houses provide an Eagle DFM. Some just have a table with the values. A given board turns out vastly differently when the rules are changed.

I've found it much less likely to have errors when the rules match the capabilities.

That said, FreeDFM complained about Gerber files from Eagle that met the DFM checks for Advanced Circuits (4PCB). Perhaps their rendering algorithms differed somehow. I usually decide whether to move things enough to avoid the warnings, increase the copper size, or just ignore them. The boards always turn out and pass ET.

That said, I've never had an issue uploading Gerber from Diptrace, along with CSV BOM and PnP files for PCB fab and assembly (although I do edit the BOM and PnP files a bit to match their formatting examples and part numbers).

It always seems that people who design in EasyEDA get good results and those who import from anything else, or miss out doing that altogether have problems and moan about JLCPCB.  A key thing is they don't claim to be compatible with a footprint standard that I can't remember the name/number of - they've gone their own way.
