I would be grateful if some experienced designers could evaluate the attached proposed footprint design and provide any feedback. I've had trouble with similar packages in the past. Not sure if it was the footprint design, pcb fabricator, or the assembly house.
The footprint details I am planning on using are at the bottom of the pdf attachment.
Forgive me for using inches on a metric 2mm x 2mm part.
Klaus,
About 10% of the circuits built with a similar IC that this will replace have had a failure related to processor communication with the part. I've asked for x-ray analysis from the factory and buzzed out failed PCBAs, but no obvious answers yet.
