Secret: What is the purpose of the IC socket with positive and negative pin marking or requiring a semicircular notch? What are the functions of IC sockets?

Edit: Administrator Browse: Time: 2019-09-18

Dongguan IC socket manufacturers need to distinguish between positive and negative pins for mass production of IC integrated circuit chips, but they still need to have a semi-circular gap in the IC socket. What is the reason for this? Today, I will tell you what is the cause and what role does the IC socket have?
The purpose of the IC socket with a semi-circular notch:
Because the IC socket is inserted into the integrated circuit after soldering, and the integrated circuit has a direction, the direction of the integrated circuit is based on the semicircular arc in the pattern of the integrated circuit on the circuit board, that is, the semicircular grooves of the integrated circuit must be aligned Semi-circular arc on the board. However, after the IC socket is soldered, the semi-circular arc on the board is covered and cannot be seen. Therefore, when soldering, it is required that the semi-circular notch (called a semi-circular groove) of the IC socket be aligned with the semi-circular arc on the board. When inserting the integrated circuit, the semi-circular groove on the IC socket is used as the standard. In other words, the three semicircles must be the same, so that the integrated circuit is inserted correctly. If the IC socket is soldered backwards, insert the integrated circuit in the direction of the IC socket, and the integrated circuit is reversed. Therefore, the integrated circuit chip socket has a semi-circular notch.

The role of the IC socket:
First: The function of the IC socket is to facilitate the insertion of the IC card.
Second: Multi-pin integrated circuits are called ICs, and the sockets that can be inserted into ICs are integrated circuit sockets, also called IC sockets. There are various specifications such as 8, 16, 18, and 20 pins. As shown in the figure:

Third: IC (Integrated Circuit) is a miniature electronic device or component. Adopt a certain process to interconnect transistors, resistors, capacitors, inductors and other components and wiring required in a circuit, make it on a small or several small semiconductor wafers or dielectric substrates, and then package them in a tube case Into a micro-structure with the required circuit function.
Fourth: The function of facilitating the removal of the chip. With the IC socket, the chip can be directly inserted and removed without using an electric soldering iron for soldering, which is easy to replace.

The above is the difference between the positive and negative pins of the IC socket. However, it is still required that the IC socket has a semi-circular notch and what are the related introductions of the role of the IC socket. I hope that this article can help everyone.
