How does the LGA socket connect?

[CoolaxGaming]

Can anyone give me a detailed explanation on how's the CPU connects to the mobo on the lga 1150/2011/xxxx socket?

A friend claims that the pins undergo something called the spring action.

By connect, I don't mean like electric connection. I mean how the CPU physically connects to the socket.

My understanding is at the CPU simply rests on the pin, and we lock it using the retention arm. But so the pins undergo this so called "spring action"?

The arm presses the cpu in the socket ? There is actually quite some force on the retention arm

So your CPU has pins and the board has "holes" for it, it fits right in but you have to carefully place it.

The pins are by nature springy IIRC, but I'm not sure of a mecahnism of action here. There are the two nubs on the sides of the CPU's PCB that keep it centered and the retention arm that presses on the IHS. That pressing action ensures the CPU stays in there firm, and as such keeps the pins connected to the contacts.

LOL what?

 

The pins are on the mobo for Intel

That is older designs, this one has pins on mobo....

Do the pins move?

Not sure but I think they do a little bit, since the movement isn't straight down, think they should get pressed down so yeah they kinda move

Nope, other way around for LGA sockets, CPU has contact points, mobo has pins.

The pins are bent sideways so they naturally have some flex to them allowing the CPU to press them down to make contact with all of them.

 

 

No springs involved as that would make it far too mechanical for durability.
