With PGA chips, there is a risk of bending pins during shipping without some sort of "bumper" material around the substrate to minimize/eliminate contact between pins and anything else.
This is true, granted if the chip is packed tightly enough with enough matieral around the chip then it should be find. In order for the pins to bend they must come in contact with something, but if they are in the middle of packing matieral, i don't see what could cause such a thing to occur. Nothing within the box can cause harm is even if the CPU was bouncing around, nothing could cause enough force to bend a pin(asumming all that's in the box is packing material), and if it's packed tightly enough the CPU won't/barley move at all. Having a bumper at the bottom of the chip does protect it better no doubt, but it's really not nesscirary in this case imo.
The only real issues comes from how it's shipped. If the carrier is not mindful, then it can cause serious damage.(like if it gets crushed by a bigger box, even though most carriers i think understand that putting a smaller box under a bigger box is idiotic.)
