Recovery diode, referred to as FRD, is a semiconductor diode with good switching characteristics and short reverse recovery time. It has unidirectional conductivity like ordinary diodes. It is mainly used in switching power supplies, pulse width modulators, inverters and other electronics. In the circuit, it is mainly used as a high-frequency rectifier diode, a freewheeling diode or a damping diode.

Zener diode (also known as Zener diode or reverse breakdown diode) is a surface contact type crystal diode made of silicon material. After the reverse breakdown of the PN junction, the terminal voltage does not change with the reverse current transformation within a certain range. The housing materials of the Zener diodes are mainly glass, plastic and metal. Generally, low-power Zener diodes are packaged in glass or plastic, and high-power Zener diodes are packaged in a metal shell with good heat dissipation. Since Zener diodes are generally made of silicon semiconductor materials, they are also called silicon Zener diodes and silicon Zener tubes.

Semiconductor refrigeration, also known as electronic refrigeration, or thermoelectric refrigeration, is a discipline developed from the 1950s at the edge of refrigeration technology and semiconductor technology. It uses PN junctions composed of special semiconductor materials to form thermocouple pairs and produce Perle The post effect, a new type of refrigeration method through direct current refrigeration, together with compression refrigeration and absorption refrigeration, is called the world's three major refrigeration methods.

Due to the extremely high added value of wafer production, the status of semiconductor testing equipment in the semiconductor industry has become increasingly prominent. In 2020, China's semiconductor testing equipment market will reach 17.6 billion yuan. With the continuous development of China's semiconductor industry, the market size of China's semiconductor testing equipment is expected to approach 40 billion yuan.

The semiconductor industry is currently one of the fastest growing industries in the world, widely used in aviation, aerospace, medical, automotive, electronics and other fields. Semiconductor packaging plays a vital role in the development of the semiconductor industry.
