DFN 4 Pins - Side (Not Bottom Only)

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

   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.

	https://www.digikey.co.uk/products/en?keywords=SIT8008BI-12-33E-36.000000E 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
