Perhaps someone can give me an opinion on this one.
I've been asked to approve the design of a surface mount device which has QFP
type legs, 0.75mm wide on a 1.4mm pitch.
The vendor is recommending a PCB pad layout for the device where the pads are
1.05 wide on (obviously) a 1.40mm pitch. The part would be used in high volume
consumer electronics.
Would anyone out there anticipate any soldering problems with this geometry? I
had a look through IPC-SM-782 but didn't find it much help.
Thanks,
