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).

Last year, the LED lighting industry and M&A events surged. According to the incomplete statistics of the High-tech Research Institute LED Research Institute (GLII), there are more than 100 related M&A cases, and the M&A amount exceeds 10 billion yuan. Among them, there are more than 20 M&A cases of listed companies in the LED industry chain, and the amount of M&A exceeds RMB 6 billion. It is expected that the scale of LED companies to be acquired in the future will no longer be limited to small enterprises.
“In 2014, the number of LED main industrial chain enterprises was 15,000. It is expected that the number of enterprises will be reduced by several thousand by 2015.†Zhang Hongbiao, research director of the LED Research Institute of Gaogong Research Institute, believes that this year will be a year of determining the company’s life and death. The number of large and medium-sized enterprises will increase, and the LED industry will have 10 billion enterprises.
Among the listed companies, Tongfang, Guangri, Foshan Lighting, Hongli Optoelectronics, Changfang Lighting, Lehman Optoelectronics, Jingyuan Optoelectronics, Lianjian Optoelectronics, Feile Audio, Moso Power, etc. all involve mergers and acquisitions. For example, Tongfang's shares of 900 million Hong Kong dollars into the real Mingli, Jingyuan mergers and acquisitions, Maoshuo power supply nearly 200 million purchase party is up to 55% stake, Lianjian Optoelectronics acquired the new three board company Easystar, Chau Ming Technology "according to Xiao Boda" acquisition Lanpu Technology, Snowlight 495 million acquisition of Fushun Optoelectronics, Wanrun Technology acquired Rishang Optoelectronics, Qinshang Optoelectronics acquired 51% equity of Caiyida.
From this level, it is not difficult to see that the excellent enterprises in the industrial chain have been actively deployed, and the story of "strong and strong" is being played in the process of survival of the fittest in the industry. Recently, "High-tech LED" reporters visited a number of LED companies and found that many companies are strikingly consistent in their actions, and their managers have expressed their actions or intentions to expand production capacity this year.
Quan Jinsong, executive deputy general manager of Shenzhen Zhaochi Energy-saving Lighting Co., Ltd., told the reporter of “High-tech LED†that “the company’s new base was completed in September last year, and the production line has increased from 200 to 400, and the production capacity has doubled. Zhang Luhua, project director of Shenzhen Smect Optoelectronics Co., Ltd. also told reporters that "the company's current production capacity is around 400 KK per month, and this year it will continue to expand production, which is expected to reach 900 KK";
Zhang Xiaobo, director, deputy general manager and general manager of the marketing department of Zhaoqing Emerald Electronic Technology Co., Ltd., revealed that the company will further expand and strengthen this year with the advantages of the new three-board financing.
"This year and next year is critical, the market is in a rapid growth period. If you do not seize the market and do not form strategic cooperation with customers, there will be no chance. Therefore, Oudiming will adopt a positive expansion strategy this year." Zhang Xiaobo said that this year's market is very optimistic, 2015 Year is both stress and opportunity. Through the company's listing on the New Third Board, it will increase capital investment and strive to achieve the transfer to the GEM.
It seems that "the strong and strong" is the same law. Why is this happening? Looking at the phenomenon through the phenomenon is nothing more than the following reasons.
First, large companies themselves tend to be more risk-resistant. In the course of business operations, mistakes in decision-making, inaccurate judgment on the market, bad debts, etc. are inevitable, small enterprises lack funds, financing difficulties, and often hundreds of thousands, or even tens of thousands of losses will lead to problems, and large enterprises Otherwise, the right to spend money to buy lessons.
Second, the comprehensive strength of large enterprises cannot be compared with small enterprises. “If my production capacity goes up, the cost will naturally come down.†Zhang Luhua gave an example. The price of one ton and two tons of materials like glue is naturally different. In addition, the production of 100 products and the production of 1,000 products naturally The average cost of 1000 products is lower. In this way, large enterprises have more advantages in controlling production costs than small enterprises.
From the product itself, products from large companies tend to be more cost effective. In addition to the above mentioned production costs, in terms of equipment, the new generation of equipment is definitely better than the previous generation equipment in terms of performance and efficiency, but the purchase of new equipment is a big one. Small enterprises are often unable to purchase new equipment, and large enterprises can easily purchase the latest equipment. The gap will be further opened over time. The products produced by large enterprises are superior in quality and cost, which is undoubtedly a virtuous cycle.
It is precisely this kind of reason that determines the situation of "strong and strong", but this does not mean that small enterprises have no chance to speak. Small enterprises should foster strengths and avoid weaknesses and avoid direct confrontation with large enterprises. To put it simply, you know what you are doing and what you can do to find the rules that suit your survival. 
LED industry interpretation "stronger Hengqiang"
[Text|Reporter Wen Zhao] In 2014, LED companies “acts†frequently, and the scope of integration and acquisition involves the entire industry chain. In the context of the industry entering a period of change, companies with technological and financial advantages are accelerating their expansion and arranging future markets in order to seize market opportunities when the pattern has not yet been determined.
