two rings surrounding thermal pad of CY8C20434-12LKXI (32 QFN)

Version 1
    Question: There are two rings surrounding the thermal pad on the bottom of the chip. Is it safe if they are all connected together (soldered in manufacturing)?



    Yes, they can all be connected. In fact, they are connected internally. The reason Amkor, our package supplier, makes them that way is for bonding and stress relief purposes.
