thanks for the help, bt i want the footprint pattern for the PCB Layout.
What kind of layout software are you using? Different software packages use different library formats.

Learning and mstering the art of making footprints is a very important discipline in any EDA workflow.
I would recommend you try this yourself.
Also, please advise for what device you need the footprint as the generic description above is not sufficient to make a footprint for you anyway.

If you don't want to, or can't, make your own footprint, attached is a Pr0tel 98 library with a footprint that will fit your device. The one you want in the library is named QFP14X14-80(N).

ROFLMAO, yep 782 is the older std that is replaced by the 7351.
What PCB package are you using, perhaps someone has the footprints already made in a library for it available.

IPC-7351 covers any footprint you want to create, what IPC-7351 does is set up the tolerences and pad sizes required for heal, to and side solder fillets etc, placement courtyards, also the naming format for both the footprint but also the padstack. If you buy the IPC-7351 spec you get a copy of the calculator, worth the money.

In the case of surface mount devices attached to double-sided or multilayer boards, each component pad is usually connected by a short length of track to a via which forms a link to other conducting layers, and this via is known as a fan-out via. The term fan-out via is generally also taken to include any vias that fall inside the dev
