I understand that the "Auto generate Pin 1 Indicator Line" is new to the proposed IPC-7351 Iss.C, where as the 'Dot' has been around for years, but takes up valuable room etc, so we would like to take advantage of using this new feature.

 

Your default preference file that is supplied in the generic 'Drafting/Legend' tab, has neither function 'activated', so I activated the "Auto generate Pin 1 Indicator Line" only.

 

Unless I'm blind and not looking correctly, I was surprised to see that the following Component families do not appear to create a Pin 1 Indicator Line:- BGA, CGA, LGA, Pullback QFN & Pullback QFN with Tab. (All of these will create a Pin 1 Dot) 

 

The DFN 2 pin 'Demo' does not create a "Pin 1 Indicator Line", but does create a Pin 1 Dot and a Chamfer outline on the Assembly layer, There is a warning that device is too small for Silk Screen?

 

 

 

There is also inconsistency with Side Concave Package (4pin), the following will create a Pin 1 Dot, but not a "Pin 1 Indicator Line", Capacitor, Crystal, Fuse, Inductor, Resistor. Only the Diode & LED create both.

 

Thanks.

The Preferences are filled with rules that you cannot violate. If a rule is violated, certain things happen. Example: You set your Silkscreen Legend Line Width, Clearance and map to Max., Nom. or Min. body in the drafting tab. Then when you create a part that is too small to meet all those rules nothing happens or you get a message "Geometry is too small for Legend outline". 

There are 2 ways to add a Legend Outline and save it to FPX file. 

The Pin 1 indicator Line can only be used on component families where the terminal leads are outside the package (like Gull Wing and J-Lead) and not underneath the package. 

Sounds like you can use a free webcast training on Library Expert to ask all your questions and get all of then answered.
