Saying goodbye to traditional industries with high energy consumption and high pollution, the LED industry, known for its environmental protection, energy conservation and high efficiency, has rapidly emerged in Zhangye Town. Yesterday, the town’s mayor Luo Yonghui excitedly told reporters that this year the town’s digital tube production reached 1.8 billion, accounting for half of the country’s total. The output of secondary light-emitting tubes has also reached more than 1 billion. Zhangye has become an important LED industry in China. base.
In 2006, Zhang Wei, who is rich in mineral resources, is determined to bid farewell to the traditional building materials industry that his ancestors lived on, to accelerate structural adjustment, transform and develop, and take a new path of sustainable development. Among the many emerging industries, the town has taken a two-step strategy by focusing on the LED industry, which started in the 1980s and has a good industrial base. The first step is to formulate an industrial plan and lead the development with planning as the leader. Zhangye Town has planned 40 hectares of LED optoelectronic industrial parks with R&D and production functions and supporting relevant supporting policies to attract enterprises to concentrate on development. The second step is to change the development concept and help enterprises to get rid of the idea of ​​Xiaofu Zean. In May of this year, the main leaders of the town organized the town's large-scale LED production enterprises to go to the Pearl River Delta, the most important LED industry base in China. This trip has not only enabled the local LED manufacturers to catch up with the upstream and downstream enterprises in the Pearl River Delta, but also caused fundamental changes in the minds of business owners.
The LED industry in Zhangye Town, which has been quietly developing for more than 20 years, has undergone rapid qualitative changes. In order to lose the old hat with high labor intensity and small scale, LED leading manufacturers such as Xingguang Electronics, Jingzheng Electronics and Ark Technology will achieve large-scale production and reduce production costs by upgrading the equipment level. Ark Technology invested more than 6 million yuan to actively introduce advanced equipment. Without increasing the number of workers, the output has doubled. Zhu Zhiping, the boss of the enterprise, has a detailed calculation. As long as the enterprise operates normally for five years, the labor cost saved and the increased output value can offset the equipment cost. At the same time, the LED enterprises in the town actively extend the industrial chain, enhance product levels through independent innovation, and actively develop landscape lighting, LED large screen, automobile lighting, traffic signals and other promising civilian cities. The new LED production enterprise of the town is passed by Shenglei Technology. Cooperated with Tsinghua University to develop LED large screen, mastered the world's most advanced surface mount welding and lamp drive one or two large LED large screen production process, and became the first enterprise in the city to have complete independent production capacity in LED large screen finished products. At present, one-third of the 32 LED manufacturers in the town have exported their products, and they have joined the bright revolution in the world with the theme of replacing traditional light sources with LED products.

Multilayer PCB consist of 3 or more circuit layers bonded together by a thickness of insulating material called prepreg and core. They came into the industry with the advent of SMD population. They are found almost everywhere, wherever electronics are in use – from aircraft to motorcycles, and storage power stations to photovoltaics.
Multilayer PCBs are most complicated than others, and are generally considered to be the most sophisticated PCB product due to their construction methods and design complexities.
BentePCB offers multilayer printed circuit boards with the following special technologies:
· Edge plating for shielding and ground connection
· High frequency base materials for applications up to 80 GHz
· Cavities, countersunk holes or depth milling
· Thick copper up to 105μm (inner and outer layers)
· 500μm thick copper inlays using HSMtec technology
· Solder resist in green, white, black, blue, grey, brown, etc.
· Controlled impedances (single, differential, etc.)
· All recognised Printed Circuit Board industry surfaces available
