DFN's and LGA's are in the same component family. 

The Terminal Leads are 100% under the package. 

Therefore a Periphery solder joint goal is the only option. 

However, the part that you are referring to is not a DFN package. It's a Side Concave Oscillator.

I cant use manufacturers recommendation as I've been told by production pads are too large and cause issues.

Wondering why when you select 4-pin DFN it defaults to No Lead Side but then when you put calculations in it changes to No Lead Bottom Only (Periphery)?

I have manually changed calculations to get what I want (0.2 toe, 0 side, 0 heel) but interested to know if there's a way of selecting No Lead Side for these types.

Many thanks,
David

Are you sure it's a 4-pin DFN? 

I would use the mfr. pattern and build it in FP Designer. 

All unique patterns are created there.

Hi All, 

I'm trying to create a 4 pin DFN (Oscillator) with side terminals so I need a toe but all settings seem to be for bottom only (periphery). 

Is it possible to set to Flat No-Lead Side (as seems an available option in the terminal preferences). 
 
Many thanks Smile
