Detailed explanation-1: -In an LGA architecture, the pins are in the socket instead of on the processor.

Detailed explanation-2: -Common types of CPU sockets include the Pin Grid Array (PGA) and the Land Grid Array (LGA). The difference between the two is that PGA places the pins on the processor and the holes in the socket, whereas LGA has a socket with pins that you place the processor on.

Detailed explanation-3: -Modern CPU sockets and processors are based on a pin grid array (PGA) architecture.

Detailed explanation-4: -LGA sockets are one of the latest socket technologies for x86 LGA microprocessor packages that range in size up to 4200 pins. These sockets can provide a compressive electrical interface to the microprocessor package and are solder ball, surface mount attached to the PCB.

Detailed explanation-5: -An easy way to recall what kind of processors LGA and PGA indicate is by using their names – Land Grid Array and Pin Grid Array. LGA – Land, i.e., Flat CPU with no pins, motherboard sockets with pins. PGA – Pins, i.e., Not Flat – CPUs with pins, Motherboard sockets without pins.
