Fast Recovery Diode (FRD) is a semiconductor diode with good switching characteristics and short reverse recovery time. It is mainly used in switching power supplies, PWM pulse width modulators, inverters and other electronic circuits as high-frequency rectifier diodes. Free-wheeling or damper diodes are used. The internal structure of the fast Recovery Diode is different from that of an ordinary PN junction diode. It belongs to a PIN junction diode, that is, a base region I is added between the P-type silicon material and the N-type silicon material to form a PIN silicon wafer. Since the base area is thin and the reverse recovery charge is small, the fast recovery diode has a short reverse recovery time, a low forward voltage drop, and a high reverse breakdown voltage (withstanding voltage).

Founded in 2002, Cui Tao Automation is committed to being a world-class supplier of semiconductor packaging equipment. Its products include chip sorting machines, solid crystal machines, wire bonding machines, glue spraying machines, spectroscopic tape machines, and dispensing machines. On November 9, 2011, the Tsui Tao Automation Semiconductor Packaging Equipment Base project was officially signed and settled in Dongjiang High-tech Industrial Park. The base project is expected to have a total investment of 300 million yuan, specializing in the production of semiconductor packaging equipment. The total area of ​​the project is about 33,000 square meters. It is estimated that the annual output value of the project will reach 600 million yuan after it is put into production.

The jury believes that Cui Tao Automation silently pursues the technological expansion of “high gold content†and opens up a new road for domestic gold wire bonding machines. It has started the localization of guns, and the road to localization of equipment has become wider and wider. 
Cui Tao Automation won the title of “The Most Developed Potential Enterprise in Chinaâ€
From December 9th to 10th, the 2011 High-tech LED Annual Conference was held in Shenzhen Qingqing World as scheduled. The most exciting moment is the "2011 High-tech LED Annual Awards Appreciation Evening", which was staged at 19:00 on the evening of the 9th, and was called the "Oscar" ceremony in the LED industry. After nearly two months of selection, the major awards. It was announced one by one that night.
