I use a similar naming fashion, just the mfr&series for example JOHNSON_142-0711201-L where the L means left if required. The "CPAD" may be redundant because the pad is already in the "custom pads" partition.]]> Tue, 06 Nov 2012 13:08:20 +0000 https://www.PCBLibraries.com/forum/naming-convention-for-odd-shaped-padstacks_topic662_post2291.html#2291 <![CDATA[Naming Convention for Odd shaped padstacks : For odd shape or irregular shape...]]> https://www.PCBLibraries.com/forum/naming-convention-for-odd-shaped-padstacks_topic662_post2278.html#2278 Author: Nightwish

For odd shape or irregular shape pad our naming convention is CPAD_CELL NAME. The picture show an example to this. CPAD means it is custom defined pads. The padstack is used for a WURTH inductor. If we want the Solder mask or paste different than the pad we choose to add a suffix _SM or _SP to the padstack name.

I have FETs with similarly large numbers of vertices in some of my designs... looking forward to a consistent naming scheme also.

BTW, I joined the 'family' for real today with my purchase - really looking forward to where this is all going...!

There is no IPC standard padstack name for a user defined contour (irregular) pad shape.
 
But I guess we're going to have to figure one out once we get to the export part of our new "Package Editor" which will allow you to easily create this library part in the V2013 PCB Footprint Expert.
 
Maybe we'll have to leave the irregular padstack field open for the User to define. This is highly customized with many (17) vertexes.

Thanks Tom but I was wondering about the padstack name, not the symbol name. 

 
The padstack for the drain on this MOSFET is a very odd shape. 
 
The view in the data sheet makes appear to look like a castle with 4 turrets.

The footprint name would be - SON_ALPHA&OMEGA_AON742

 
Component Family _ Mfr. Name _ Mfr. Part Number
 
So your library will always sort on the component family and then the Mfr. and then the Part Number.

Allegro PCB Editor has the ability to create Odd shaped padstacks and associate them with pins within the symbol. 

 
I was wondering about naming conventions however. 
 
What would you recommend for the padstack name associated with the Drain on this MOSFET?
