DIPs are commonly used for integrated circuits (ICs). Other devices in DIP packages include resistor packs, DIP switches, LED segmented and bargraph displays, and electromechanical relays.
DIP connector plugs for ribbon cables are common in computers and other electronic equipment. |

A specialized tool called a PLCC extractor facilitates the removal of a PLCC from a socket.
This package is still used for a wide variety of device types, which would include memory, processors, controllers, ASIC, DSP, etc. Applications range from consumer products through automotive and aerospace. |

A pin grid array, often abbreviated PGA, is a type of integrated circuit packaging. In a PGA, the package is square or roughly square, and the pins are arranged in a regular array on the underside of the package. The pins are commonly spaced 2.54 mm (0.1") apart, and may or may not cover the entire underside of the package.
PGAs are often mounted on printed circuit boards using the through hole method or inserted into a socket. PGAs allow for more pins per integrated circuit than older packages such as dual in-line package (DIP). |

| Slot 1 Pentium IIs were intended to replace the Pentium and Pentium Pro processors in the home, desktop, and low-end SMP markets. The Pentium II Xeon, which was aimed at multiprocessor workstations and servers, was largely similar to the later Pentium IIs, being based on the same P6 Deschutes core, aside from a wider choice of L2 cache ranging from 512 to 2048 KB[1] and a full-speed off-die L2 cache (the Pentium 2 used cheaper 3rd party SRAM chips, running at 50% of CPU speed, to reduce cost). |

| Socket A (also known as Socket 462) is the CPU socket used for AMD processors ranging from the Athlon Thunderbird to the Athlon XP/MP 3200+, and AMD budget processors including the Duron and Sempron. Socket A also supports AMD Geode NX embedded processors (derived from the Mobile Athlon XP). The socket is a zero insertion force pin grid array type with 453 pins (nine pins are blocked in the socket to prevent accidental insertion of Socket 370 CPUs, hence the number 462). The front side bus frequencies supported for the AMD Athlon XP and Sempron are 133 MHz, 166 MHz, and 200 MHz. Socket A supports 32-bit CPUs only. |

Socket 478 (also known as mPGA478, mPGA478B) is a 478-contact CPU socket used for Intel's Pentium 4 and Celeron series CPUs.
Socket 478 was launched with the Northwood core to compete with AMD's 462-pin Socket A and their Athlon XP processors. Socket 478 was intended to be the replacement for Socket 423, a Willamette-based processor socket which was on the market for only a short time. Socket 478 was phased out with the launch of LGA 775. |

| Socket 754 is a CPU socket originally developed by AMD to succeed its Athlon XP platform (socket 462, also referred to as Socket A). Socket 754 was the first socket developed by AMD to support their new consumer version of the 64 bit microprocessor family known as AMD64. |

| LGA 775, also known as Socket T, is an Intel desktop CPU socket. LGA stands for land grid array. Unlike earlier common CPU sockets, such as its predecessor Socket 478, the LGA 775 has no socket holes; instead, it has 775 protruding pins which touch contact points on the underside of the processor (CPU) |

LGA 1366, also known as Socket B, is an Intel CPU socket. This socket supersedes Intel's LGA 775 (Socket T) in the high-end and performance desktop segments. It also replaces the server-oriented LGA 771 (Socket J) in the entry level and is superseded itself by LGA 2011. LGA stands for land grid array. This socket has 1,366 protruding pins which touch contact points on the underside of the processor (CPU) and accesses up to three channels of DDR3 memory via the processor's internal memory controller.
Socket 1366 (Socket B) uses QPI to connect the CPU to a reduced-function northbridge that serves mainly as a PCI-Express controller. A slower DMI is used to connect Intel's most recent northbridge and southbridge components. By comparison, Intel's socket 1156 (Socket H) moves the QPI link and PCI-Express controller onto the processor itself, using DMI to interface a single-component "chipset" (now called PCH) that serves traditional southbridge functions. The difference in pin number is mostly a reflection of the number of memory channels served. |

| Socket AM3 is a CPU socket for AMD processors. AM3 was launched as the successor to Socket AM2+ on February 9, 2009, alongside the initial grouping of Phenom II processors designed for it. The sole principal change from AM2+ to AM3 is support for DDR3 SDRAM. |
