Judging from the situation in the second half of this year, the LED lighting market has not been able to continue the booming situation in the first half of the year. Many LED companies have been caught in overdraft and have difficulties in operation. In this kind of adversity, how to manage difficulties with dealers and inject new strength into development has become an urgent issue for manufacturers.
Usually under this circumstance, the exhibition investment and channel deepening become the two magic weapons for enterprises to expand sales channels.
At present, many LED manufacturers have good reputations, but in the end they have not formed scale sales. They are not good or bad. The lack of channels is the ability to combine vertical and horizontal. The channel is ecological, and without the ability to work, it will eventually be eliminated.
A great feature of this year's high-tech LED lighting exhibition is to effectively integrate the resources of downstream application channels, and provide convenience for manufacturers to connect with distributors, engineering companies, designers and other resources as much as possible. In this exhibition, LED lighting brand manufacturers accounted for about 80% of the total number of booths, the main position of application companies and channel providers has been strengthened, and opened a professional buyer to negotiate a special area, and strive to strengthen the on-site trading function of the exhibition.
However, a good exhibition not only requires an audience, but also requires a professional audience and professional buyers. Because the quantity and quality of professional visitors and buyers directly affects the exhibitors' participation efficiency, it is also important for the exhibition organizer's service quality. reflect.
However, because the invitation of the professional audience requires the resources of the organizer in the early stage, some organizers only care about the amount of money earned by the exhibition, and the invitation to the professional audience and the buyer does not care. However, the number of buyers is not much, why the effect of the exhibition is reflected. This kind of "only recruiting and not attracting business" situation is everywhere in China.
As a high-end media in the industry, Gaogong hopes to set the characteristics of the exhibition and set it as the industry benchmark. The organizer has increased the invitation of professional visitors and buyers, and strives to increase the number of professional buyers to provide the best service for exhibitors. For this reason, we have also launched the industry precedent of “unsatisfactory, refundâ€.
The organizing committee will arrange the qualifications of the local distributors by arranging the reporters from various stations, and will focus on the strength of the dealers. In the invitation of overseas professional buyers, Gao Xiaocheng CEO Zhang Xiaofei went to North America to discuss with local buyers.
At the same time, the organizing committee also integrated overseas LED import and export traders, distributors, overseas lighting associations, media, testing institutions and other resources to obtain more than 10,000 valid international buyers, focusing on China's major LED lighting exporters. , one-on-one invitation.
The three major exhibitions in October will be a good opportunity for high-tech LED lighting exhibition organizers to invite professional visitors and buyers. Gaogong LED hopes to invite more high-quality visitors and buyers to provide the best service for the exhibitors of 2013 Gaogong LED Lighting Exhibition.
In addition, in October, the high-tech LED lighting exhibition promotion team will also distribute the exhibition materials and exhibition materials in the Guangdong region (shenzhen, Guangzhou, Zhongshan, Jiangmen, Huizhou, Dongguan and other places). The high-tech LEDs in the 29 provinces of the country will also be stationed in the local lighting stores, engineering companies and other channels to distribute "Exhibition" and related exhibition promotional materials, invite outstanding dealers across the country to join the 2013 high-tech LED lighting professional buyers team.
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.
