2021 Differences

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I'm about to start using 2021 instead of 2020. In previous major upgrades, I would generate a new preferences file, diff it with my previous preference file, and copy over anything from the old version that I wanted to keep. However, the new options file uses a different format, so I can't compare my old preferences to the new options.
So, can you summarize what has changed between the default preferences for 2020 and the default options for 2021?

If I use an FPX from 2020 and generate a footprint in 2021, am I going to see changes in the output?

Thanks,

John

	The V2021 is the future for all updates and new features. V2021 was rewritten 100% from scratch and has a new user friendly interface. The Options are much more User Friendly. Save your .opt file and edit your Options. Use the Translator (2021 FPX File Converter.exe) in the main installation folder to translate your old FPX file to the new V2021 format. The latest release in V2021.08 pre-release. And there will be another update later today or tomorrow. Print out Page 2 of Chapter 5 user guide. It will help you with learning the new toolbar icons. The User Guide is in the installation /documents folder.

	As an additional specific question. In 2020 I changed the default fab tolerance to 2500 (from 5000), but otherwise mostly kept the default settings. What changes, if any, would be needed in 2021 to achieve the same output?

	There is an IPC-7351C .opt file that turns off manufacturing tolerances and changes all negative solder joint goals to 0.00. But you can do whatever you think is best.

	Oh, fabrication and placement tolerances are global now. I was looking for them in the wrong spot. Have the default solder goals and courtyard sizes changed at all between 2020 and 2021?

	Yes, they are now in the Tools > Options > Pad Stack Rules. Much easier to edit now.
