Shanghai World Expo 38 enterprise investment to create LED cube
The Shanghai Enterprise Joint Pavilion of the 2010 Shanghai World Expo signed an official participation contract with the Expo Bureau on December 14. The museum was jointly funded by 38 large and medium-sized enterprises under the Shanghai State-owned Assets Supervision and Administration Commission. The funds are now in place. Because it is an ecological building with intelligent technology, dreamy mood and interactive experience, the Shanghai Enterprise Joint Pavilion is nicknamed Rubik's Cube.
It is understood that the architectural design of the Shanghai Enterprise Pavilion is inspired by the traditional Chinese Taoist thoughts of Tiandi and the romantic story of Zhuang Zhou Mengdie. The whole exhibition experience will be divided into Jingying Shenyin, into Pujiang, Shanghai Road and future journey. In the four areas, visitors will enter the pavilion and will travel with a dialogue between a grandfather and granddaughter. The integrated interactive experience lasts for 17 minutes.
The Shanghai Enterprise Pavilion covers an area of ​​about 4,000 square meters. Its façade material is made of polycarbonate transparent plastic tube, which is easy to recycle. The rainwater in the site will be recycled, precipitated, filtered and stored. Spray can not only reduce the local temperature, but also control according to the program, forming a colorful pattern on the building facade together with the LED lights. Interestingly, the Shanghai Enterprise Joint Pavilion has a solar collector screen on the roof of the building, and the output electric power is more than 200 kW, which can meet the daily electricity consumption and exhibition needs of the Rubik's Cube.

Standard PCB
A Printed Circuit Board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. Components (e.g. capacitors, resistors or active devices) are generally soldered on the PCB. Advanced PCBs may contain components embedded in the substrate.
PCBs can be single sided (one copper layer), double sided (two copper layers) or multi-layer (outer and inner layers). Conductors on different layers are connected with vias. Multi-layer PCBs allow for much higher component density.
FR-4 glass epoxy is the primary insulating substrate. A basic building block of the PCB is an FR-4 panel with a thin layer of copper foil laminated to one or both sides. In multi-layer boards multiple layers of material are laminated together.
Printed Circuit Boards are used in all but the simplest electronic products. Alternatives to PCBs include wire wrap and point-to-point construction. PCBs require the additional design effort to lay out the circuit, but manufacturing and assembly can be automated. Manufacturing circuits with PCBs is cheaper and faster than with other wiring methods as components are mounted and wired with one single part.
Here at BentePCB, Standard PCB means manufacture parameter in General requirements, no special features.
