What is an LGA package?
(Land Grid Array) A chip package with a very high density of contacts. LGAs differ from traditional chips with protruding pins that are inserted into a socket. An LGA chip has flat pads on the bottom of its package that touch contacts on the motherboard socket.
What is LGA in PCB?
The land grid array (LGA) is a type of surface-mount packaging for integrated circuits (ICs) that is notable for having the pins on the socket (when a socket is used) rather than the integrated circuit.
What are LGA components?
LGA devices can be used for either lead containing or lead-free assemblies depending on the surface mount technology (SMT) assembly solder pasted used. LGA eliminates risk that customers receive components with missing or damaged spheres due to shipping or handling.
Which is better LGA or PGA?
The motherboard can hardly be damaged by CPU misalignment. (More Durable Motherboard) It is much easier to repair bent pins on a PGA processor than on a LGA motherboard. (Slightly Better Repairability)
Does AMD use PGA?
AMD has long stuck with a pin grid array (PGA) for its CPU packaging. The other popular alternative is a ball grid array (BGA), which is widely used today, primarily in mobile devices. The reason we’ve not seen it much on desktop is because BGA designs actually see the chip soldered permanently to the socket.
Does Intel use LGA or PGA?
In the modern computing era, Intel CPUs use LGA sockets, while AMD CPUs use PGA.
How many types of BGA are there?
Technically, these package types fall into three main categories: Ceramic BGA (CBGA) Plastic laminate BGA (PBGA) Tape BGA (TBGA)
What is a flip chip BGA?
A flip chip BGA is a specific type of ball grid array that makes use of a controlled collapse chip connection, or flip-chip. It works though solder bumps on the top of the chip pads. The process starts with integrated circuits on the wafer. Pads are metallized on the chips and solder balls are placed on each pad.
Why does AMD use PGA?
While a shift to LGA may seem somewhat trivial, the change will mark a major shakeup in AMD’s desktop lineup. AMD has long stuck with a pin grid array (PGA) for its CPU packaging. The reason we’ve not seen it much on desktop is because BGA designs actually see the chip soldered permanently to the socket.
Is AMD replacing AM4?
According to a tweet from Executable Fix, a well-known leaker, AMD will finally move away from PGA to LGA with the shift to AM5, the new socket set to replace AM4. They also note that a coming generation of AMD chip will support DDR5 and PCIe 4.0 with a 600-series chipset.
Why does AMD still use pins?
The processors are less likely to be damaged by mishandling and drops, because of no fragile pins. (More Durable CPU) LGA pins are smaller in physical size, allowing for more pins in the same amount of space. (More Space Efficient)
