Super ContributorHi,
what kind of failure do you observe, missing connection or short to other pins?
I see a previous discussion related to 64-pin EQFP package https://community.intel.com/t5/Programmable-Devices/Max-V-Stencil-Design-64-Pin-Plastic-Enhanced-Quad-Flat-EQFP/m-p/1574520#M94757
I think, a comfortable option is to place vias beneath the exposed pad, this way you don't need to care for solder drain through vias. As mentioned in my previous post, EQFP package has the problem of clearance tolerance between pad and PCB, about 0.05 to 0.15 mm. You need to supply suffient solder paste to safely bridge the gap.
