How are diodes produced?

When it comes to the semiconductor industry, it has two major branches, namely integrated circuits and discrete devices. As a very important basic component product, discrete devices can realize functions such as rectification, voltage stabilization, switching and frequency mixing in electronic equipment. A large number of applications in the fields of network, automotive electronics, electronic instrumentation, LED display, power management, industry and automatic control.

Discrete devices include semiconductor diodes, transistors, MOSFETs, bridge rectifiers, thyristors, TVS, bridge optoelectronic devices, etc. A diode is a very common discrete device. It is a two-electrode electronic component with asymmetric conductance. An ideal diode has zero resistance between the two electrodes (anode and cathode) when it is conducting forward, and infinite resistance when it is reversed. , that is, current is only allowed to flow through the diode in one direction. Common diodes include rectifier diodes, switching diodes, Schottky diodes, Zener diodes, TVS diodes, high frequency diodes, etc.

Seeing this, you may be curious, how are diodes produced? This article analyzes the production process of Youfeng Micro Factory to give you a deeper understanding of the production process and details of diodes.

The structure of the diode includes PN junction + shell + lead wires. The purchasing personnel of Youfeng Micro will transport the materials to the packaging and testing center after the preparation is OK. For processes such as rib cutting, product testing, marking, tape braiding, and finished product packaging, Youfengwei has a dedicated environmental testing laboratory, product appearance analysis laboratory and other professional laboratories. The company's products must undergo strict testing. All-round testing guarantees product quality, and only qualified products can be shipped to customers.
