I'm starting a project involving High Brightness LEDs,
and I want to use some Metal Core boards for thermal management.
Anyone have any suggestions on where to get
Metal Core Boards in low protype quantities?
I know of this one, are there others?:

Perhaps the attached will be of use. I built a board using this symbol
and package and it works.

Especially if the spec sheet comes from Freescale -- their tech writers

Orcad layout needs a dot.mnl file and orcad capture generates a number of
formats mnl bien sure plus hdl, spice etc. There is also an alegro option I
think that is a universal format. Capture is very popular and I was told
they use alegro to export to other layout tools. I prefer gschem to orcad
I haven't looked in the library, but this part should be
there. Instead of looking for a TQFP, look for a QFP or a
PQFP. This is an old footprint and should be very common.
If all else fails, you can download a footprint dimension library
from PCB Libraries at http://www.pcblibraries.com/. T

Hello,
I need a 100-pin TQFP footprint with 0.65mm pitch:
100-Pin Thin Plastic Quad Flat pack (14 x 20 x 1.4 mm) (51-85050)
In datasheet

Ok, It works now :-)
