QFN packages in CADstar

[johndohn]

Hi!

I'm using an old version of CADstar (ver. 10.0) and I'm having difficulties finding footprint for the QFN-16 package. I tried to make one myself with the LCC wizard, but it didn't work.

Does anyone know where to get a library with QFN-16 package? The component I'm trying to work with is LTC3544B ( LTC3544B - Quad Synchronous Step-Down Regulator: 2.25MHz, 300mA, 200mA, 200mA, 100mA - Linear Technology )

Thanks!

Yes I have one, but I think if you are going to do PCB design, creating component footprints is critical. Practice.

Ditto the above.

http://cds.linear.com/docs/Packaging/QFN_16_05-08-1700.pdf has the dimensions.

This can be done using the wizards and then adding the inner pad - it should take you about 20 minutes in all.
(Quicker once you are practised)
