Quan Jian also stated that compared with last year's LED sales during the Singles Festival, online sales in early January this year were 18 times that of Singles. At the same time, a person in charge of a midstream company stated that 2013 is a very important year. Even the share of Philips' lighting equipment in its group business will increase from about 10% last year to about 70%. Therefore, All LED manufacturers are opportunities.
Compared with the entire LED market, LED outdoor lighting is one body position.
According to relevant statistical data, in the first quarter of 2013, the bidding for street lamps and tunnel lights in Guangdong Province from January to March 2013 had reached 76,000, and the amount of tenders in the first quarter exceeded the total amount of tenders in the previous year.
In May last year, the Guangdong Provincial Government formally issued the "Guangdong Province's Implementation Plan for the Promotion of the Use of LED Lighting Products." It requires that all new construction projects in the public lighting area of ​​the province use LED lights from the date of implementation of the plan. LED lighting products will be completed in batches before the end of 2013. After nearly a year of brewing, the plan has entered an accelerated implementation period.
"The current number of tenders is only a small part of the popularization policy. With the further implementation of the popularization policy, the amount of follow-up bidding will be even greater." Quanjian said that not only Guangdong is vigorously promoting LED lighting, but also under the banner of energy-saving emission reduction. All local governments have promoted LED lighting as an important policy.
Based on this, Li Xuliang, Chairman of Qinshang Optoelectronics, stated: “Last year, the number of tenders for LED street lamps and tunnel lights by local governments was limited. In 2013, the market will enter a concentrated outbreak period.â€
Pan Wenbo, the founder of Guangzhou International Lighting Exhibition, the largest lighting exhibition in the world, predicts that LED outdoor lighting will become the fastest growing segment of LED lighting in the next three years. In 2015, outdoor LED lighting market in China will be close to 15 billion yuan.
It is worth noting that not every LED lighting company can benefit from this wave of LED outdoor lighting. The results of the tender announced by the Science and Technology Department of Guangdong Province showed that most of the companies that bid for the bidding project for the government street lamps are listed companies. If Qinshang Optoelectronics successfully won the bidding for a number of street lamp renovation projects in Guangzhou and Qingyuan in the first quarter, Hongli Optoelectronics also won the bid for Zhuhai and other street lamp renovation projects.
In this regard, Pan Wenbo analysis said that in addition to the high performance requirements of lamps and lanterns, the majority of street lighting promotion using EMC (contract energy management) model requires companies to advance funds, so listed companies benefit more.
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.
LED market may enter concentrated outbreak period
“This year, the international environment has improved, domestic policies support, and the LED industry has picked up momentum. The relevant experts in the industry even predict that this year will be a big outbreak in August.†Quan Jian, President of Guangdong Lighting Association, at the China Lighting LED Industry Development Seminar 2013 Right.
