Good day to all. Got a dumb question here: we just got back some proto boards done=20 with the PIC 18F67J60. Went to populate the boards - whoops! Got a=20 problem here. The TQFP-64 package that was in the CAD library doesn't match the PIC=20 received from Digikey. Turns out that the TQFP package in the CAD library has a 0.80mm lead=20 pitch whereas the PIC has a 0.50mm lead pitch. Like I said: Whoops! So - my co-worker is busy making a new footprint to match the actual=20 chip. But that has me wondering: how do people define these footprints? I did some minor searching via Google and find that we aren't the=20 only people perplexed by this - Microchip apparently offers TQFP=20 packages with 4 different lead pitches: 0.40mm, 0.50mm, 0.65mm, 0.80mm. I'm looking for suggestions as to how to name these footprints - I'd=20 like to follow whatever convention has been developed rather than=20 come up with something totally different from what everyone else uses. This particular incident wasn't my mistake but it easily could have=20 been - I'm sorta used to a package name (eg SOIC) having a specified=20 lead pitch and I might have decided to skip my usual "check twice"=20 policy. As it was, I did have a good look at the board layout before=20 it was sent out and it *NEVER* occurred to me that the PIC footprint=20 might be wrong. dwayne --=20 Dwayne Reid Trinity Electronics Systems Ltd Edmonton, AB, CANADA (780) 489-3199 voice (780) 487-6397 fax www.trinity-electronics.com Custom Electronics Design and Manufacturing --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
