IC: Integrated circuit, the specific function of the circuit with a certain mode package together, only let the pin exposed, composed of integrated block circuit, can be divided into magnetic closed, plastic closed and soft closed. Non-ic: refers to other basic components other than IC, that is, resistors, capacitors, etc., including a wide range. IC, commonly known as chip, refers to integrated circuit. There are many categories of electronic components, such as resistors, capacitors such as a single device called the basic device, and the chip, is to integrate a lot of basic devices into a very small circuit board, which is called a chip, that is, an integrated circuit, so it can also be called a non-IC basic component, IC is called an integrated circuit.
