Anhui Sanan Optoelectronics Co., Ltd. (hereinafter referred to as Anhui Sanan), a subsidiary of Sanan Optoelectronics, is located at No. 8 Dongliang Road in the development zone.
The reporter found that most of the workers entering the factory area were young people in their twenties. One of the workers told the reporter that most of the equipment in the factory area was in operation. "We are very busy every day."
It is undeniable that in the winter of the LED industry, relying on government subsidies, the days of Sanan Optoelectronics have been quite moist.
On July 16, Sanan Optoelectronics announced its 2012 semi-annual performance forecast. It is expected that the net profit attributable to owners of the parent company will be 450 million yuan to 470 million yuan in the first half of this year, thanks to the company's wholly-owned subsidiary Anhui. The release of Sanan's production capacity will be released. The net profit for the same period last year was 459 million yuan.
However, it is still unknown how long such a good day can last.
Not yet fully operational
Due to the domestic investment boom in the LED industry, the overall upstream and downstream industrial chain prices of LEDs fell sharply in 2011.
Sanan Optoelectronics' 2011 annual report also showed that the gross profit margin of the company's leading product chip sales fell sharply by 43.47% year-on-year.
Sanan Opto's 2012 first quarter report showed that its total profit was 270 million yuan, but 150 million yuan of it came from non-operating income, most of which was financial subsidies.
In addition, it achieved a net profit of 200 million yuan in the first quarter of this year, but the "net cash flow from operating activities" was only 130 million yuan, which means that the sales of products did not accompany the return of full cash.
On June 29, Shenzhen's well-known LED company, Vision Optoelectronics Co., Ltd. (hereinafter referred to as Vision Optoelectronics), declared bankruptcy due to a broken capital chain. This is the second time that a well-known LED display manufacturer has closed down after the collapse of the company and the collapse of Bolent.
The LED industry is struggling and it is hard to deny.
In the winter of the industry, financial subsidies have gradually become the profit model of some enterprises.
Sanan Optoelectronics has shown a low-cost expansion path for the market: using the characteristics of local governments to pursue economic growth, signing investment cooperation agreements with local governments, and achieving local expansion subsidies.
Outside the factory in Sanan, Anhui, the reporter found that this is a large-scale enterprise. It took almost 15 minutes to walk from the third gate in the south to the door in the east.
According to the announcement of Sanan Optoelectronics, Wuhu Municipal People's Government will provide the company with about 1200 mu of land in the northern part of Wuhu Economic and Technological Development Zone as the project industrial land, and reserve 800 mu of land in the eastern area as the industrial land for the later period of the project.
However, the factory was quite deserted, and did not see the trucks waiting for transportation or the hot work scene.
A security guard told reporters that the factory is mainly a closed working environment. "The products of our factory do not need trucks to transport."
According to the announcement of Sanan Optoelectronics, Anhui Sanan is its non-public offering investment project in March 2010, and the 2.98 billion yuan of investment funds have all been used up. After the project is completed and put into production, it will form an annual output of 5.3 million pieces of ultra-high brightness LED red, yellow, blue and green light epitaxial wafers and a production capacity of 117 billion chips.
According to the announcement of Sanan Optoelectronics, the first phase investment of this plant will reach 6 billion yuan, and all the 103 equipment purchased have arrived at the company. As of the end of the first quarter of this year, 70 units have been officially put into production.
"At present, only 90 of the 103 equipments in Anhui Sanan Phase I have been put into production." A staff member told reporters.
From the current construction and operation of the entire plant area, the east side of the plant, administrative building and staff dormitory building have been completed, but in the west of the fourth door is overgrown, there is no sign of construction.
For the grass near the No. 4 gate, the above staff told reporters that this is the second phase of construction land. “In fact, construction has already started, and two factories have been capped. Near the western part of the grass, there is also a foundation to fight.â€
Treasury is about to close
The completion of the first phase of Anhui Sanan and its mass production have been inseparable from the support of the local government.
During the investigation in Wuhu, the reporter learned that the Wuhu Municipal Government's policy support for Sanan Optoelectronics was very strong and gave a large amount of financial subsidies.
The reporter received a notice from the Wuhu Municipal Government on the promotion of certain policies for the development of the LED industry (hereinafter referred to as the "Notice"). It can be clearly seen that "the company purchased 50 sets of MOCVD equipment for the production of LED epitaxial wafers that have reached the international advanced level." The above, and the related industries such as chip and package, application product R&D and manufacturing are all invested and produced in Wuhu. According to the blue-green MOCVD equipment (limited to 55-chip machines and above), each of the highest not more than 12 million yuan, red and yellow MOCVD equipment (Limited to 55 tablets and above) Each of the maximum not exceeding 9.6 million yuan, given a one-time research and development subsidy support."
For the financial subsidies of Sanan Optoelectronics, the Wuhu Municipal Government subsidizes each of the total amount of 8 million yuan for each of the red and yellow MOCVD (limited to 38-piece machines and above), giving blue-green MOCVD (limited to 31-chip and above) each. The 10 million yuan subsidy was implemented.
Throughout 2011, Sanan Optoelectronics “government subsidies for the current profit and loss†reached 805 million yuan, which was more than ten times higher than the 56.06 million yuan in 2009. This does not include “closely related to the normal business of the company. A government subsidy that meets the requirements of national policies and continues to enjoy a certain amount or quantity according to certain standards."
Anhui Sanan achieved a net profit of 326 million yuan in 2011, including many financial subsidies from the Wuhu municipal government.
“There are some subsidies, but not all.†A staff member of the company told reporters that the “technical three†financial subsidies are recorded in the current profit and loss. “However, the subsidies for MOCVD equipment are confirmed upon receipt. Deferred income is amortized over profit or loss over the useful lives of related assets."
According to the "Notice" of the Wuhu Municipal Government, the policy support for the LED industry is valid until December 31, 2012. In other words, Sanan Optoelectronics will not receive financial subsidies from the Wuhu Municipal Government after 2013.
The above staff told reporters that the financial subsidies for the first phase of Anhui Sanan have all been received. "As for the second phase, there are subsidies. It is not easy to say for the time being."
If the days of the LED industry continue to be difficult, Sanan Optoelectronics may not be able to stand alone.
"Recently, several large-scale LED downstream enterprises in Shenzhen have closed down. We believe that the performance of large and medium-sized enterprises in the middle and lower reaches is a sign of industry consolidation and industry reshuffle. This is a sign that the industry is doing well. Some of them are weak. Corporate failure is not a bad thing, the key is how long it will take to wash," said Zhang Xiaoda, a researcher at Haitong Securities. 
Four basic structural components of automobile connector
1. Contact
It is the core part of automobile connector to complete the electrical connection function. Generally, the contact pair is composed of positive contact and negative contact, and the electrical connection is completed by inserting the female and male contacts. The positive contact is a rigid part, and its shape is cylindrical (round pin), square cylinder (square pin) or flat (insert piece). The positive contact is generally made of brass and phosphor bronze.
The female contact, namely jack, is the key part of the contact pair. It relies on the elastic structure to produce elastic force due to elastic deformation when it is inserted with the pin, and forms a close contact with the positive contact to complete the connection. There are many kinds of Jack structures, such as cylinder type (split slot, shrink mouth), tuning fork type, cantilever beam type (longitudinal slot, 9-shaped), box type (square socket) and hyperboloid linear spring jack.
2. Shell
Also known as the shell, it is the cover of automobile connector, which provides mechanical protection for the built-in insulation mounting plate and pin, and provides the alignment of plug and socket when inserting, so as to fix the connector to the equipment.
3. Insulator
Insulator is also called automobile connector base or insert. Its function is to arrange the contact according to the required position and spacing, and to ensure the insulation performance between contacts and between contact and shell. Good insulation resistance, voltage resistance and machinability are the basic requirements for selecting insulating materials to be processed into insulators.
4. Annex
Accessories are divided into structural accessories and installation accessories. Structural accessories such as snap ring, locating key, locating pin, guide pin, connecting ring, cable clamp, sealing ring, sealing gasket, etc. Install accessories such as screws, nuts, screws, coils, etc. Most accessories have standard parts and general parts. It is these four basic structural components that enable the automotive connector to act as a bridge and operate stably.
Application characteristics of automotive connector
From the use purpose of the automobile connector, in order to ensure the better driving of the car, we can divide the reliability of the connector into the sealing property in use and the fireproof performance in the driving of the car. In addition, in the driving of the car, the connector can also show the shielding performance and temperature control performance. In general, when discussing the sealing property of automobile connector, the sealing performance of automobile connector is not only for water.
In this field, the current international management standard is IP67, which is also the highest level in the automotive closure industry. Although the waterproof requirements are different in different parts of the car, many automobile manufacturers will choose IP67 to ensure the airtight performance of their car connectors.
In the driving of the car, power supply is a very important energy source, not only related to the normal work of the engine, but also often involved in the use of power supply in the process of driving. Therefore, in the automotive power system, the automotive connector has different division, between the male connector and the equipment, between the male connector and the cable, between the male and female connector, and between the female connector and cable, there are certain sealing measures that can be implemented.
Sealing ring is a common tool in the sealing performance of automotive connector. This tool can not only achieve the effect of fixing between different hole positions, but also achieve the sealing effect. It can not only ensure the stable operation of automobile equipment, but also ensure the waterproof performance of automobile equipment in work. Most of the sealing rings are made of silicone rubber, which is made of liquid silicon and solid silicon after certain chemical changes.
Now the car is in use, electronic circuit technology is an important aspect of the automotive industry, not only in the driver's entertainment, but also in the driver's driving car control system, electronic circuit technology plays an important role in the stable work of the car. In order to ensure the stable work of electronic circuit technology, people have applied a lot of shielding technology in automobile production.
These shielding technologies not only play a protective role in the electronic circuit of the automobile, but also have the ability of anti-interference and anti radiation in the parts of the car. In addition, they can also play a protective role for the stable work of the automobile connector. These can be divided into two types of external shielding and internal shielding.
When using external shielding to protect automobile connector, two identical shielding shells are usually assembled together to form a shielding layer, and the length of the shielding layer can cover the whole length of the connector. On the shielding layer shell, there should be enough locking plate structure to ensure the reliable installation of the shielding layer. In addition, the shielding materials used should not only be treated by electroplating, but also be treated to prevent chemical corrosion.
The future trend of automotive connector
At present, the global automotive connector industry accounts for about 15% of the connector industry. In the future, it is expected to take a larger proportion under the drive of automotive electronic products. In terms of product cost structure, the average cost of connectors used in each car in China is only a few hundred yuan, compared with that of foreign countries
