Hi all,
I use Orcad 10.5 at work, and I am on the process of laying down a board
that has several TQFP parts. In particular I have a TQFP 144 package
that when I decided to check the footprint in the Orcad layout library
seems odd...
When I compared the part's pin width and length, it is larger than the
footprint's pads size. I always thought that it would be the other way
around but then looking at some example boards from several
manufacturers it seems, as the pin density increases, they make the pads
the same dimensions as the pin or smaller.
I would be grateful for your advice and if you have any info on
standards it would be great.
Best regards
		Luis
