[Text / high-tech LED Yue Mengdi] In January, the company ushered in the lifting of the ban, many LED companies were increased by the company's executives, from top to bottom are full of confidence in the company. However, in the wave of increase in holdings, it is naturally also reduced by shareholders.
Dehao Runda (002005) announced on the evening of January 26 that the controlling shareholder of the company, Wuhu Dehao Investment, reduced its holdings of 8 million shares and 23 million shares on March 20, 2015 and January 25, 2016, respectively. Shares, a total of 31 million shares, accounting for 2.22% of the company's total share capital.
After the reduction, Wuhu Dehao Investment holds 292 million shares of the company, accounting for 20.94% of the company's total share capital, and remains the controlling shareholder of the company.
On January 27th, it was no surprise that Dehao Runda's stock fell on the opening, opening at 6.13 yuan. As of 09:59, the stock fell 9.98% to 5.59 yuan, closing the daily limit. The investment software shows that in the past 5 days, the total outflow of the stock has flowed out to a total of -12,459,300 yuan, lower than the industry average.
Then, on the evening of January 27th, Dehao Runda announced the announcement again. On January 26, 2016, Wuhu Dehao Investment and Haitong Securities handled the pre-purchase repurchase business of stock pledged repo, and held it. 54,000,000 shares of the company were purchased in advance.
In the investor circle, they are stunned and they have decided that this is another sign of a big fall. Sure enough, on January 28, Dehao Runda fell another 7.14%, closing at 5.33 yuan. "The stock price has been at a low level in recent years, and funds have begun to enter the market, but the current market is weak, and the market may continue to explore." A stock trader of Guotai Junan told Gaogong LED.
In fact, as the first batch of companies to enter the LED industry, Dehao Runda was the beginning of the road to march. Gaogong LED looked through the public information and found that in March 2009, Dehao Runda acquired the LED assets of Guangdong Jianlongda and entered the LED industry. From October to May 2011, Wuhu, Yangzhou, Dalian and Chongqing were established respectively. LED photoelectric industry base. Thus fully enter the LED industry.
Since 2008, the domestic government has started to subsidize MOCVD policy support. The degree of subsidies varies from place to place, and each MOVCD can receive a minimum of 8 million subsidies. Gaogong LED understands that from 2009 to the first half of 2015, Dehao Runda has won a total of 1.344 billion yuan of government subsidies, but still has not been able to "whitewash" the annual report of almost annual losses.
In March 2013, Dehao Runda held a 20.05% stake in NVC and held a 27.03% stake in NVC Lighting by the end of 2014, further opening up production and sales links to achieve a complete industrial layout of LEDs. I thought I could make up the downstream channels in one fell swoop, but I didn't want the dispute between the two. The internal consumption was amazing.
From the 2015 semi-annual report of Dehao Runda, in 2015, the company's operating income in the first half of the year was 2.05 billion yuan, and the profit was 14.89 million yuan. The low profit margin made people unable to bear to look straight.
In August 2015, Dehao Runda announced that it intends to cooperate with state-level industrial funds to jointly acquire assets of a lighting enterprise outside China, involving a total amount of RMB 4 to 6 billion. On January 19th, the company made a preliminary assessment of the value of the assets of the M&A, and produced the transaction proposal (non-binding quotation letter) of the M&A business, which was submitted to the assets on January 15, 2016 (Beijing time). The seller.
The speculation of this "offshore lighting enterprise assets" is naturally the OSRAM Lighting Division.
The sale of Philips Lumileds has been officially suspended, and the sale of Osram has not been conclusive. Whether Dehao Runda can take advantage of the acquisition of “a certain lighting enterprise asset outside the countryâ€, change the previous trend, raise the stock price, and let investors regain confidence in the company, which is worth looking forward to.
Via In Pad PCB
What is Via In Pad? In shortly,via in pad is the via holes are at the SMD pad.The vias are very small,usually under 0.3mm.Why and how? First is there is no enough space to layout,you have to put the vias and holes closer even together.Second it helps thermal management and for high frequency boards,it may help improve signals.
Because the SMD pads are for SMD components loading,so the solder can not flow to inner layer or the other side when assemble.That is the most important for via in pad board.
How PCB manufacturers like us to do via in pad board? We will fill all vias with non-conductive epoxy and plate copper over it ,so the vias are flat same as others. Many PCB factories are unable to do such capability.
The key technology is how we fill vias and guarantee there is no any solder (surface finishing) in the holes.
Filled via in pad is a way to achieve intermediate density with an intermediate cost compared to using blind/buried vias. Some of the key advantages associated with using the via in pad technology are:
.Fan out fine pitch (less than .75mm) BGAs
.Meets closely packed placement requirements
.Better thermal management
.Overcomes high speed design issues and constraints i.e. low inductance
.No via plugging is required at component locations
.Provides a flat, coplanar surface for component attachment
Via in big pads are not a big problem.but for BGA,that is technology.As BGA pads are very small,10mil or 12mil,and there is no enough space.Manufacturing is not easy as other boards.
