The overall dimensions of a DIP package depend on its pin count, which may be anywhere from four to The area between each row of pins is perfectly spaced to allow DIP ICs to straddle the center area of a breadboard. This provides each of the pins its own row in the board, and it makes sure they don't short to each other.
They're inserted into one side of the board and soldered into place on the other side. Sometimes, instead of soldering directly to the IC, it's a good idea to socket the chip. Using sockets allows for a DIP IC to be removed and swapped out, if it happens to "let its blue smoke out.
There is a huge variety of surface-mount package types these days. In order to work with surface-mount packaged ICs, you usually need a custom printed circuit board PCB made for them, which has a matching pattern of copper on which they're soldered. Here are a few of the more common SMD package types out there, ranging in hand-solderability from "doable" to "doable, but only with special tools" to "doable only with very special, usually automated tools".
It's what you'd get if you bent all the pins on a DIP outward, and shrunk it down to size. With a steady hand, and a close eye, these packages are among the easiest SMD parts to hand solder. On SOIC packages, each pin is usually spaced by about 0. Mounted on a board in the middle quarter added for size-comparison. Splaying IC pins out in all four directions gets you something that might look like a quad flat package QFP.
Sometimes they wrap around, and are exposed on both the side and bottom, other packages only expose the pad on the bottom of the chip. These are amazingly intricate little packages where little balls of solder are arranged in a 2-D grid on the bottom of the IC.
Sometimes the solder balls are attached directly to the die! BGA packages are usually reserved for advanced microprocessors, like those on the pcDuino or Raspberry Pi. Usually, to put these packages onto a PCB requires an automated procedure involving pick-and-place machines and reflow ovens. Integrated circuits are prevalent in so many forms across electronics, it's hard to cover everything.
Here are a few of the more common ICs you might encounter in educational electronics. Logic gates, the building blocks of much more ICs themselves, can be packaged into their own integrated circuit. Logic gates can be connected inside an IC to create timers, counters, latches, shift registers, and other basic logic circuitry. Microcontrollers, microprocessors, and FPGAs, all packing thousands, millions, even billions of transistors into a tiny chip, are all integrated circuits.
These components exist in a wide range in functionality, complexity, and size; from an 8-bit microcontroller like the ATmega in an Arduino , to a complex bit, multi-core microprocessor organizing activity in your computer. These components are usually the largest IC in a circuit. As these components grow in complexity, the package gets equally complex.
Modern digital sensors, like temperature sensors, accelerometers , and gyroscopes all come packed into an integrated circuit.
These ICs are usually smaller than the microcontrollers, or other ICs on a circuit board, with pin counts in the three to twenty range. Integrated circuits are present in just about every circuit out there. Now that you're familiar with ICs, why not check out some of these related concept tutorials:.

An integrated circuit IC is made up of silicon material. A plain piece of silicon is called a wafer on which the circuit is printed. The silicon wafer contains metallic pins from its two sides. The process of making ICs is called fabrication.
ICs are placed on circuit board either by sticking their pins or fixing them in a socket or house. It works by receiving and sending signals on the circuit board from which it is powered up.
Each leg or pin of IC has a different job. Functions like sending and receiving data, power to run it, and many others are performed by different pins. Integrated Circuit technology is used in designing powerful processors. The mainframe computers mainly use them. These processors are built from silicon wafers on which the transistors and connections between them are printed at the nano scale. Therefore, billions of transistors are printed on a single silicon chip or wafer.
For example, a transistor can allow a certain amount of voltage to enter a part of a circuit by using a gate which will open at a specific voltage. In this way, a transistor sends the data throughout the system. The microprocessor is the most important part of the IC. The main purpose of the microprocessor is to provide memory to the system. It also provides memory to perform calculations and follow a certain logic or protocol.
The protocol or the logic tells the microprocessor how to process the data and electricity throughout the system. These components work together within an integrated circuit to carry out different operations. There are many ICs in which the numbers of these electronic components exceed the number of humans on earth. Integrated circuits are in almost every electrical appliance today, from wristwatches to televisions and from juice makers to PCs.
The applications of ICs are limitless.
