Several types of sockets motherboard types you should know. Currently, some are used, such as LGA, BGA, and PGA, but there are other types. In this article, you'll learn about them all, as well as their advantages and disadvantages.
SIP
Un SIP socket (Single In-line Package) It is a type of socket or connector used to mount and connect integrated circuits (ICs) in electronic devices. The term "single-in-line" refers to the arrangement of the IC's pins in a single row, as opposed to double-in-line packages such as DIP (Dual In-line Package).
The SIP socket is mainly used in applications where integrated circuits need be replaced or updated frequently. It provides a mechanical and electrical interface between the IC and the printed circuit board (PCB), allowing the IC to be easily inserted and removed from the socket without soldering.
The SIP socket consists of a plastic shell which houses metal contacts inside. These contacts align with the IC pins and provide a reliable electrical connection between the IC and the PCB. SIP sockets are designed for a variety of sizes and pin configurations, allowing them to accommodate different types of ICs.
The main The advantage of SIP sockets is the ability to replace or upgrade ICs quickly and easily without the need for soldering. This is useful in applications such as prototyping, circuit testing, product development, and repairs, where ICs need to be swapped frequently. In addition, SIP sockets also provide protection to the IC and PCB by preventing heat damage during the soldering process.
There were no notable CPUs with this type of socket…
ZIP
In this case it is similar to SIP or DIP, only instead of having a single row of pins like SIP, it has two like DIP. However, unlike DIP, the pins are not aligned on both sides of the chip, but are in the form of zig-zag in a line. Hence its name Zig-zag In-Line Package.
DIP
Un DIP socket (Dual In-line Package) It is a type of socket or connector used to mount and connect integrated circuits (ICs) in electronic devices. The term "dual in-line" refers to the arrangement of the IC pins in two parallel rows.
The DIP socket is widely used in applications where integrated circuits are intended to be permanently mounted on a printed circuit board (PCB). It consists of a plastic or ceramic housing which houses a series of metal contacts. These contacts align with the IC pins and provide a stable and reliable electrical connection between the IC and the PCB.
El assembly process Inserting an IC into a DIP socket involves inserting the IC's pins into the corresponding contacts on the socket. The pins and contacts are designed to fit snugly together and form a secure connection. Once inserted, the IC is firmly held in place and can transmit electrical signals between the IC and the PCB.
Throughout history there have been many chips for this type of socket, such as the MOS Technology 6502, the Motorola 6800 and 68K, the Intel chips prior to the 80186, etc.
PLCC
El PLCC socket (Plastic Leaded Chip Carrier) It is a type of socket or connector used to mount and connect PLCC-type integrated circuits (ICs) in electronic devices. The term "plastic leaded" refers to the plastic casing that houses the IC, and "chip carrier" refers to the type of IC packaging.
PLCC ICs are integrated circuits that have pins or terminals on all four sides from the package, and these pins extend outward in a square or rectangular pattern. The PLCC socket is specifically designed to house and connect these PLCC ICs.
The PLCC socket consists of a plastic base with a series of metal contactsThese contacts are located inside the socket and are designed to make contact with the pins of the PLCC IC when inserted into the socket. They provide a secure and reliable electrical connection between the IC and the printed circuit board (PCB).
El assembly process Installing a PLCC IC into a PLCC socket involves aligning the IC pins with the corresponding contacts in the socket and then pressing the IC down until the pins make contact with the socket contacts. This ensures a proper and stable connection between the IC and the PCB.
There have been many examples of this type of CPUs, such as the Intel 80186, 80286, 80386, AMD compatible models, and many others.
PGA
Un PGA (Pin Grid Array) socket It is a type of socket or connector used to mount and connect integrated circuits (ICs) in electronic devices. The term "pin grid array" refers to the arrangement of IC pins in a matrix or grid.
In a PGA socket, the IC pins are located at the bottom and extend outward in the form of a two-dimensional array. The PGA socket has a contact structure that matches the pin configuration of the IC, allowing for a precise and secure connection.
The process of mounting an IC in a PGA socket involves align the pins of the IC with the corresponding contacts in the socket and gently press the IC down so that the pins make contact with the socket contacts. The contacts in the PGA socket are designed to provide a solid and reliable electrical connection between the IC and the printed circuit board (PCB).
From the Intel 80386 until very recently, most CPU sockets have been of this type on x86. But also outside this family, such as those on the DEC Alpha, IBM PowerPC, Intel Itanium in its initial versions, HP PA-RISC, etc.
PGA ZIF
It is not a socket per se, but rather an improvement over the previous one. While the first PGAs had to be inserted by pushing the chip once the holes matched the pins, in the ZIF (Zero Insertion Force) You don't need to force anything, hence the name. To do this, they have a lever on the side, as seen in the image above. You just have to raise it at a 90° angle to the socket to release the pins for inserting or removing the chip. Once this is done, you lower it, securing the pins.
BGA
It's not a socket per se, but it's good to know about, as it's the most commonly used socket for laptop processors. BGA (Ball Grid Array) It is a type of packaging used in integrated circuits (ICs) in electronic devices. In a BGA, electrical connections are made by small solder balls arranged in a grid pattern on the bottom of the IC. These solder balls make direct contact with the contacts on the printed circuit board (PCB), allowing for a reliable electrical connection. BGA packaging is widely used in applications requiring high pin density and improved heat dissipation, such as processors, memory chips, and high-power devices. It offers advantages in terms of performance, reliability, and thermal efficiency, although its installation and repair can be more complex due to the need to solder the solder balls.
LGA
El LGA (Land Grid Array) socket It is a type of socket or connector used to mount and connect processors to motherboards. Unlike PGA (Pin Grid Array) sockets, where the pins are on the processor, in the LGA socket the pins are located on the motherboard. The processor, on the other hand, has a series of contact pads that align with the pins on the LGA socket. During installation, the processor is placed in the LGA socket and pressed down so that the pads make contact with the socket pins, thus establishing the electrical connection.
Furthermore, offers advantages such as better heat distribution and higher pin density, allowing for greater processing power and improved performance in computer systems.
The most modern and advanced processors from Intel, AMD, and others already use LGA, as it allows for a higher pin density. Examples include the AMD Ryzen 7000 Series, the latest generation Intel processors, Xeon, and AMD EPYC, Threadripper, and others.
Slot
Although they were rare, there were also examples of CPUs installed in slots (Single Edge Contact Cartridge) instead of sockets, as is the case with the Intel Pentium II, Pentium III, and Celeron with their Slot 1, AMD Athlon (K7) with their Slot A, the Intel Pentium II Xeon and Pentium III Xeon with their Slot 2, etc.
To Inserting the processor here was done like any other expansion card. or RAM into its slot. It was pressed in, matching the notch on the CPU and the slot, and the side structures held the unit in place. To remove it, open the side tabs and pull it away from the CPU…
Slotet
The slotkets They are adapters that allow the use of socket-based microprocessors on slot-based motherboards.
They were initially created to allow the use of Socket 8 Pentium Pro processors in Slot 1 motherboards. Later, they became more popular for inserting Socket 370 Intel Celerons into Slot 1-based motherboards. This reduced costs for computer builders, especially for dual-processor machines. High-end motherboards that accepted two Slot 1 processors (usually Pentium 2) were widely available, but dual-socket motherboards for the lower-cost Socket 370 Celerons did not exist. Slotkets remained popular during the transition from Slot to Socket 1-based Pentium III processors, allowing CPU upgrades on existing Slot XNUMX-based motherboards.
They were never introduced to take advantage of the transition of AMD Athlon processors from the Slot A form factor to the Socket A form factor. Nowadays, slotkets have disappeared largely because Intel and AMD have not manufactured PCUs in slot form factors since 1999.
