What is the difference between ic and chip

But what's inside that black box? The guts of an integrated circuit, visible after removing the top. The real "meat" to an IC is a complex layering of semiconductor wafers, copper, and other materials, which interconnect to form transistors, resistors or other components in a circuit. The cut and formed combination of these wafers is called a die. While the IC itself is tiny, the wafers of semiconductor and layers of copper it consists of are incredibly thin.

The connections between the layers are very intricate. Here's a zoomed in section of the die above:. An IC die is the circuit in its smallest possible form, too small to solder or connect to. To make our job of connecting to the IC easier, we package the die. The IC package turns the delicate, tiny die, into the black chip we're all familiar with. The package is what encapsulates the integrated circuit die and splays it out into a device we can more easily connect to.

Each outer connection on the die is connected via a tiny piece of gold wire to a pad or pin on the package. Pins are the silver, extruding terminals on an IC, which go on to connect to other parts of a circuit. These are of utmost importance to us, because they're what will go on to connect to the rest of the components and wires in a circuit. All ICs are polarized , and every pin is unique in terms of both location and function.

This means the package has to have some way to convey which pin is which. Most ICs will use either a notch or a dot to indicate which pin is the first pin. Sometimes both, sometimes one or the other. Once you know where the first pin is, the remaining pin numbers increase sequentially as you move counter-clockwise around the chip. One of the main distinguishing package type characteristics is the way they mount to a circuit board. Through-hole packages are generally bigger, and much easier to work with.

They're designed to be stuck through one side of a board and soldered to the other side. Surface-mount packages range in size from small to minuscule. They are all designed to sit on one side of a circuit board and be soldered to the surface. The pins of a SMD package either extrude out the side, perpendicular to the chip, or are sometimes arranged in a matrix on the bottom of the chip. ICs in this form factor are not very "hand-assembly-friendly.

DIP, short for dual in-line package, is the most common through-hole IC package you'll encounter. These little chips have two parallel rows of pins extending perpendicularly out of a rectangular, black, plastic housing. 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.

A chip is a chip, which generally refers to what you can see with the naked eye that is covered with a lot of small feet or the footprints are not visible. Chip is the general term for semiconductor component products. It is the carrier of the integrated circuit IC , which is divided into wafers.

Chips also include a variety of chips, such as baseband, voltage conversion, and so on. An integrated circuit is a kind of small components or parts, and the range of integrated circuits is much wider. Even if some resistors, capacitors and diodes are integrated together, it may be an analog signal conversion chip or a logic control chip.
