I made a printout a wile back to help me when I was building a programer for a ATMEGA328p-AU using a ZIF Socket. The ATMEGA328p-AU is an SMD version for ATEMGA328p that you can burn an Arduino Bootloader into it. I hope it helps someone else out! dan.
The model numbers found on the ZIF Socket (Hope this helps people with search engines)- LQFP32 QFP32-DIP32 QFP32/D32 NO.SA663 sol P107-271B1
