Hello KBowe2,

there is the following note in the pin information document for Intel/Altera MAX V device family (https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/dp/max-v/5m40z.pdf):

The E64 package has an exposed pad at the bottom of the package. This exposed pad is a ground pad that must be connected to the ground plane on your PCB. This exposed pad is used for electrical connectivity and not for thermal purposes.

Regards,

Martin
