Earlier today, it was reported that Ding Lei, the co-founder of LeTV Supercar, the global vice chairman, and the CEO of China and Asia Pacific, also served as the global CEO of Faraday Future ("FF"), is no longer responsible for FF. Matters.
Although FF has never announced the CEO's candidate for more than two years, a source has revealed to The Verge that since Ding Lei joined LeTV as co-founder of Supercar in 2015, he has been helping to prepare for FF. Ding Lei has also been regarded as the "second-hand" of LeTV, in addition to Jia Yueting. He also served as vice president of Shanghai Automotive Group Co., Ltd. and general manager of Shanghai General Motors Co., Ltd.
According to the report of THE VERGE, FF has not appointed a formal CEO since its establishment. The company has been going through almost two years. The source told THE VERGE that LeEco has invested $1 billion and is absolutely controlling the start-up of electric vehicles. Has served the role of CEO. The report also released another rumor that Ding Lei will join Weilai Auto, an electric car startup company based in Silicon Valley, but the specific position is unknown, and it is rumored. THE VERGE also quoted sources as saying that Ding Lei still works at LeEco and his title remains unchanged. In this regard, LeTV also released an official statement on Ding Lei.
Ding Lei said that FF has always been a strategic partner of LeEco, and there is no separation. Ding Lei responded that the news was false.
MC PCB--Metal Core Printed Circuit Boards
MC PCB means metal core printed circuit boards. why use metal,not FR4/CEM-1 or others? All is to get high thermal conductivity. The most MC PCB is Aluminum PCB, Aluminum has good heat transfer and dissipation ability, but also cheaper than copper based PCB.Many customers asked a quote for MC PCB but without the thermal requirements.If you know the thermal conductivity is the most most important thing for MC PCB,then
you will know why the price is so difference. Normal thermal is from 0.8-2.00 W/m.k,and higher can up to 8.0 W/m.k,even more if you need ,but ,are you sure ? When we quote to you ,we have to ask you the thermal conductivity,it is not only about cost but your product.Many factories used low thermal ,can you use the boards?
MC PCB uses in LED lights,Industrial power equipment,Cars,Power,etc. Bergquist is the top quality metal core material but top cost as well.
Thermal Conductive Board (TCB), or Insulated Metal Substrate (IMS), provides the advantages of high thermal conductivity, reliability and solder heat endurance. The TCB substrate is a sandwich structure, which includes layers of conductor, insulator and metal base.Traditionally, this insulator is made of epoxy, epoxy filled glass fiber, polyimide, or other dielectric materials. However, these kinds of insulators could not meet the requirement in high-power electronic devices. The heat generated by these devices will accumulate, andthe life time and reliability of the end product will decrease.
Visit bergquist to get more information about high thermal.
PTTC (Polytronics) is another top quality but much cheaper than Bergquist in the word ,it is made in TaiWan .visit PTTC.
