Correct land pattern for Propellor's LQFP package
To all,
I'm laying out a board for use with the P8X32A-Q44 device and wish to know the correct land pattern to use. I think the standard name for the package can be one of the following, but can anyone tell me which is correct?
JEDEC MO-112AA-1
JEDEC MO-108AA-1
JEDEC MS-026BCB
JEDEC MS-026ACB
JEDEC MS-026
JEDEC MS-026AB
Thanks!
Mike

The Propeller datasheet ( here in this forum recently posted is a good doc for this)
Not sure if it list the jedec std number but it has the correct land pattern detail for you.

Using the PCB Libraries IPC-735X software suggests that neither the QFP nor QFN packages have direct JEDEC equivalents. Some of the packages are close but I'd be real hesitant to use them for automated assembly. At any rate the published lands seem to work fine. If anyone needs them, shoot me an email and I'll send you the Mentor Graphics PADS Suite library entries I'm using.
