In recent years, the explosive growth of the LED industry and the strong support of the national policy for the LED industry have led to the influx of funds from various companies. For the rise of environmental protection and cross-border LED, whether it is a soldier or a thousand troops, but also the right to do everything. How can we use capital and technical strength to cross-border layout? Regardless of whether it is a small business or a big strategy, if the word "daring" is the first, it will not be a hero. Tailor-made a set of "operational programs" that are more than enough to make the cross-border LED enterprises defeat the enemy.
Tongfang shares: advantages change, scale change strategy
Change will be passed, general rules will be reached, and up to the world. Chai Jing's "Under the Dome" has made LED people and LED companies have a strong responsibility. “Combining the world†did not go with enthusiasm, and the scale advantage turned into a strategic advantage, making Tongfang shares a potential stock in the LED industry to save the environment.
Tongfang's shares are based on the industrialization of scientific and technological achievements, and are mainly engaged in two major areas of information and energy environment. In 2008, Tongfang shares cost 800 million yuan for the project of “High-brightness LED chip manufacturing and industrial applicationâ€. The wealth is huge, and investment is a big deal. In 2010, Tongfang invested in the construction of a high-brightness LED application comprehensive industrial base in Nantong, Jiangsu. As of the end of the year, the accumulated investment amount was 549.12 million yuan, but the income generated in 2010 was -1.163 million yuan.
When the investment and return are not completely proportional, Tongfang’s shares have been strategically adjusted. On October 30, 2014, Zhen Mingli invested heavily in the energy-saving lighting of Sinopec Gas Station. In the same year, the wholly-owned subsidiary of Tongfang Co., Ltd. intends to obtain a controlling stake in Hong Kong-listed company Zhen Mingli by way of subscription and new shares.
This subscription has made Tongfang's shares one step closer to environmental protection, and LED development has also been added. In 2015, Tongfang Shareholding Company Zhen Mingli changed its name to “Tongfang Youyou†to expand and expand LED lighting and related energy-saving business at home and abroad.
Through the large-scale layout of Tongfang, the LED business has developed rapidly, forming an industrial structure centered on semiconductor chips, general lighting, lighting engineering, and display backlight business.
BYD Lighting: Ten years of precipitation, thick and thin hair
Looking at BYD's history of growth since entering the LED industry, it is low-key but without losing strategy. From 2003 to 2014, BYD changed from a new army in the LED industry to a veteran. Whether it is the veteran or the "Ginger", it is always the old "spicy."
BYD specializes in automotive business, mobile phone components and assembly business, secondary rechargeable battery and new energy business. In 2003, BYD began to enter the LED industry, and its early applications focused on automotive lighting and mobile phone backlighting. Avoid being “marginalized†by the industry. Three years of growth allowed BYD to focus on LED general lighting. With the strong backing of cars, IT and new energy, BYD has no worries about cross-border and has been out of control. In 2010, BYD shaped its own brand – BYD Lighting.
Ten years is not long for a company's development, but it is enough to make it a person in the industry who is "a singer is a singer, a war is a hero." In 2014, BYD's LED business achieved a total revenue of 514 million yuan, compared with a total revenue of 367 million yuan in 2013, an increase of 40.05%.
Guangdong Ganhua: Clear target, use LED to get rid of losses
Duang got rid of the loss hat, I am afraid that only Guangdong Ganhua has this "stunt". In 2011, Guangdong Ganhua was also known as “ST Ganhuaâ€, with a loss of 196 million yuan in the year. In 2012, the government subsidy was included in the current profit and loss of 728.325 million yuan (a large part of the subsidies came from subsidies for MOCVD equipment). Get rid of the loss hat and get rid of the risk of delisting.
Guangdong Ganhua mainly produces paper and biochemical products. In 2011, it invested 836 million yuan to establish a wholly-owned subsidiary, Deli Optoelectronics, to build an LED epitaxial wafer production project, and to build 20 epitaxial wafer production lines and supporting chip production lines for MOCVD equipment.
However, this small volume of Deli Optoelectronics, which started production in the second half of 2014, has not yet achieved economies of scale, and even caused Guangdong Ganhua's 2014 performance to decline.
Li Ka-shing: Star effect, lighting up gold
In the 2014 Forbes list of the world's richest people, Li Ka-shing has won the richest man in Asia with a net asset of $31 billion. From now on, the high-ranking people are not the only ones.
Li Ka Shing's name is Changjiang Industrial's main real estate development and strategic investment, Hutchison Whampoa operates ports and related services, real estate and hotels, retail, energy, infrastructure, investment and so on. At the beginning of March 2014, Li Ka-shing showed the media the nano-LED bulbs he invested. On November 21st, the "world's most energy-efficient" LED bulb Nanoleaf, which is famous for its brand effect of "Li Chaoren", was officially launched in Hong Kong and sold for as much as $35.
After the re-exposure by Li Ka-shing's hand, the LED lights immediately triggered a golden effect in the Hong Kong stock market, and many LED lighting concept stocks soared. The industrial star effect has won the spread of media from all walks of life, and has also made LED lighting more attention in the domestic market.
8 Layer PCB - Stackup & Cost & Prototype manufacture
What is 8 layer PCB?
The 8 layer PCB is a circuit board with 8 layers that are stacked firmly together with predefined and dependable mutual connections between the layers. Structure of eight layer PCB is more complicated. Nowadays, PCBs frequently have 8 to 12 layers or more, and electronics engineers know that designing for so many layers requires a well-configured layer stack.
8-layer Printed Circuit Boards are usually installed in compact equipment with strict spacing requirements, such as notebook computer motherboard, communication backplane, wearable watches, etc. Because of its complexity and high manufacturing costs, your 8-layer PCB Manufacturing should be made by reliable and experienced manufacturers. Jinghongyi PCB has been specially targeting high-end PCB manufacturing and assembly services for 8 years, providing high-quality products and services for various customers. Our advanced production line and fast response team will keep you comfortable and reassured, without any trouble, you can rest assured to place the order with us.
Typical 8-layer PCB stack up methods and guidelines
Standard stackup of 8 layer PCB looks as follows
- Signal1
- Ground
- Signal2
- Power
- Ground
- Signal3
- Power
- Signal4
Eight-layer PCB can be used to add two additional layers, or two planes can be added to improve EMC performance. Most eight-layer circuit boards are superimposed to improve EMC performance, rather than adding additional wiring layers. Compared with 6-layer circuit boards, the cost increase percentage of 8-layer PCB is less than that of 4-layer PCB to 6-layer PCB. Therefore, in order to improve EMC performance, the cost increase is reasonable. Therefore, most 8-layer boards consist of four wiring layers and four planes.

In short, 8 layer PCB are usually used to improve the EMC performance of circuit boards, rather than increasing the number of layers.
No matter how you decide on the stack layer, it is not recommended to use an 8-layer PCB Board with six wiring layers. If you need six routing layers, you should use a 10 Layer PCB board. Therefore, the 8-layer board can be regarded as the six-layer board with the best EMC performance.
Basic Layer of Eight-Layer Circuit Board with Excellent EMC Performance
All signal layers are adjacent to the plane, and all layers are tightly coupled. High-speed signals are buried between planes, so planes provide shielding to reduce the transmission of these signals. In addition, the circuit board uses multiple grounding layers to reduce the grounding impedance.
