Electronic design is also trying to reduce its size while continuously improving the performance of the whole machine. From mobile phones to smart small portable products, small is always the same pursuit. High-density integration (HDI) technology enables end-product design to be more compact while meeting higher standards of electronic performance and efficiency. HDI is currently widely used in mobile phones, digital (camera) cameras, MP3, MP4, notebook computers, automotive electronics and other digital products, among which mobile phones are the most widely used. HDI boards are generally manufactured using a build-up method. The more times the layers are stacked, the higher the technical grade of the board. Ordinary HDI boards are basically one-time laminate, high-order HDI uses two or more layers of technology, and adopts advanced PCB technology such as stacking holes, plating holes, and laser direct drilling. High-end HDI boards are mainly used in 3G mobile phones, advanced digital video cameras, IC carrier boards, etc. Pcb Hdi,Hdi Board,Hdi Pcb Design,Hdi Pcb Technology Chuangying Electronics Co.,Ltd , https://www.cwpcb.com
Recently, the first 500 kV EHV power transformer independently developed by Harbin Transformer Co., Ltd. passed the national new product technology appraisal, which marks the end of the province's history of not being able to produce ultra-high voltage power transformers.
It is reported that Kazakhstan Transformer was founded in 1955 and is a wholly state-owned enterprise in Harbin City. Currently, it is a key enterprise in the national transformer industry and a leading enterprise in the transformer industry in the province. For a long time, Kazakhstan has been producing 220 kV transformers. In 2008, Harbin Municipal Government invested 700 million yuan to build a new factory in Kazakhstan. In 2011, the construction of the 500 kV UHV transformer factory building and equipment installation at the Hachang plant was basically completed. At the same time, the company hired 500 kV transformer technology experts from the industry as the core to form a talented person who mastered the advanced transformer core technologies at home and abroad. The team finally succeeded in developing the first 500 kV EHV power transformer in our province.
It is reported that the development of Kazakhstan Transformer 500 kV EHV power transformer has successfully realized the dream of more than 20 years of people in the power transmission and transformation industry in our province. According to reports, during the Eighth Five-Year Plan period in our province, the development of a 500 kV ultra-high voltage power transformer was written into the development plan. After more than 20 years of hard work, it was finally successfully developed. It also marked that our province's power transmission and transformation manufacturing capacity has entered the national first echelon. It has the ability to provide supporting equipment for major domestic and international power stations and major power transmission and transformation projects in the national grid.
