MMA8452Q PCB layout suggestions

[martincoster]

Attached image of my MMA8452Q PCB layout. Any comments on the design? The data sheet says I should provide dangling tracks for unused pins, to reduce stress during reflow. Also kept any via's >2mm away from chip as per data sheet, and no ground plane below chip. Our application is very basic, I will just pole the chip for data once a second. I do not need interrupts. Any comments appreciated.

Hi Martin,

I just checked the part of the layout you sent and everything seems to be correct, you should not get any problem related with the layout of the MMA8452Q.

Have a great day,
Jose Reyes
