On January 4th, Zhejiang Juyi Technology Co., Ltd. was publicly listed on the national share transfer system through the transfer of the agreement.
According to the announcement, the operating income of Juyi Technology in 2013 and 2014 to January-June 2015 was 10.37 million yuan, 12.71 million yuan, and 204.396 million yuan respectively; the net profit was -855.56 million yuan, -591.82 million yuan, and 1.157 million yuan respectively. .
According to the data, Zhejiang Juyi Technology Co., Ltd. was established on April 21, 2015. It mainly produces and sells LED solar indoor and outdoor lighting products, LED automotive headlight products, LED backlight products, LED architectural lighting products, and LED packaging products. Import and export of goods, technology import and export.
By analyzing the macro-policy environment at home and abroad and the market development trend of the industry, the company has formed two major series of products based on independent research and development of LED light source direct welding technology and intelligent driving power supply, which are road/tunnel lighting. Intelligent commercial lighting fixtures.
Usually,10 & 20 layers PCB are HDI board,but some are not .Some with big trace width and space,holes are over 0.3mm too. We have much experience in doing 10 Layer PCB & 20 layer PCB.
A ten-layer board should be used when six routing layers are required. Ten-layer boards, therefore, usually have six signal layers and four planes. Having more than six signal layers on a ten-layer board is not recommended. Ten-layers is also the largest number of layers that can usually be conveniently fabricated in a 0.062" thick board. Occasionally you will see a twelve-layer board fabricated as a 0.062" thick board, but the number of fabricators capable of producing it are limited..
High layer count boards (ten +) require thin dielectrics (typically 0.006" or less on a 0.062" thick board) and therefore they automatically have tight coupling between layers. When properly stacked and routed they can meet all of our objectives and will have excellent EMC performance and signal integrity.
A very common and nearly ideal stack-up for a ten-layer board is shown in Figure 12. The reason that this stack-up has such good performance is the tight coupling of the signal and return planes, the shielding of the high-speed signal layers, the existence of multiple ground planes, as well as a tightly coupled power/ground plane pair in the center of the board. High-speed signals normally would be routed on the signal layers buried between planes (layers 3-4 and 7-8 in this case).
