Today's LeTV conference, the most eye-catching is not a cheaper than the millet surface of the 1000 LeTV as a super-curved TV, is not what the music as the fish under the home or music to watch. Even LeTV has been robbed of the limelight by a topic! That is music 414, ecological hardware free day!!


This is exactly what the concept is, according to LeTV’s introduction, Eco 4.14 was defined by LeTV as Hardware Free Day. Buy members the day, super mobile phones, super TV free to buy! Buy 3 years of super film and television members to send over 3 X40, 5 years can send S50 air, 7 and a half years members send over 3 X55 month pass, and easy to use Car value sent to the mobile phone! When everyone is still discussing Xiaomi's iQiyi membership as long as 199 yuan, LeTV uses hardware to not hit the strong millet.


Really not money?

However, it seems that LeTV has played a little conspiracy, after all, it is not really free to take, or need to pay membership fees. According to LeEco's annual fee 490, the basic required membership price is the selling price of the hardware. It can be simply understood that LeTV Super Video and LeTV Super Mobile Phones are sent to send LeTV Super Members of equal value. Although there is a certain difference from the real sense of free, it is obviously enough to fight Xiaomi. After the hardware configuration has been fully improved and the content has become a “genuine” gift, LeTV’s price/performance ratio for Xiaomi is obviously more. Emboldened.

Moreover, you should know that LeTV is still deeply collaborating with TCL on hardware, so the strength of hardware and software should not be underestimated. Such small tricks are even more useful to users than direct users. LeTV makes good use of the illusion of users' value positioning and creates a feeling of falling out of the sky. But real benefits still benefit users.


What is music like not money?

If LeSports' free big move has a little conspiracy in it, in fact, from a deeper perspective, more meaning is the ambition of market demand. In fact, from the press conference, it is not difficult for us to see that, whether it is music or other friends, the price of hardware has almost reached the bottom line, the upgraded version of the X40S is only from 1599 yuan, which shows that a good time for smart hardware has passed In this price of the Red Sea, the profit left by the business is already in jeopardy. Next, there must be competition for content, just as what Peng Xing of LeTV said: In the Internet era, users have formed new consumption concepts, brands and hardware are not core values, only content and services are the core values. When Prince Edward promoted his position and so on, and one of the popular internet dramas opened the content capital market, contention for smart hardware has become the next main battlefield for merchants. We can see some clues from Xiaomi’s launch of the 199-member membership, and LeTV’s free big move is also a means to cope with it.


In this period of time, radio and television began to “stab the killer” on the software market of smart TV boxes. The era of payment for smart TVs seems to have been getting closer and closer. In the case of copyright, this adjustment is also a pleasure for the merchants. "And users "sorrow from the middle".

What are the benefits of super membership?

So what benefits does LeTV Super Member really have? Xiao Bian simply listed for everyone

1, exciting content tailored for young members. Members' exclusive and customized solo dramas, premium online movies and other rich resources are free to look at;

2, HD library 1080P experience. Ultra HD (720P, 1080P, 2K) quality content members exclusive;

3. Cloud services and cloud acceleration channels designed for members. First to fully support the 4K (4K TV only) and H.265 video innovation cloud platform, giving priority to members to provide rapid access;

4, four-screen scene service sharing. Le Yuanyuan Film & TV members can enjoy mobile, PC, Pad and upcoming movie theater services based on cinema scenes;

5. Members watch videos without advertisements. There is no advertisement in the playback process in LeTV Video App and Le.com (except for some special copyright parties);

6. Members enjoy exclusive services provided by LeEco Ecology. Provide online and offline exclusive services for members.


It has to be said that LeTV’s press conference may be of far-reaching significance. It indicates that the free age of hardware and the era of content charging have arrived, and users have begun to transform their ideas.

Microwave PCB
microwave PCB`s is a type of PCB designed to operate on signals in the megahertz to gigahertz frequency ranges (medium frequency to extremely high frequency). These frequency ranges are used for communication signals in everything from cellphones to military radars.  The materials used to construct these PCB`s are advanced composites with very specific characteristics for dielectric constant (Er), loss tangent, and CTE (co-efficient of thermal expansion).
High frequency circuit materials with a low stable Er and loss tangent allow for high speed signals to travel through the PCB with less impedance than standard FR-4 PCB materials.  These materials can be mixed in the same Stack-Up for optimal performance and economics.
The advantages of using materials with a low X, Y and Z CTE is a resulting PCB structure that will remain extremely stable in high temperature environments while operating at up to 40 GHz in analog applications.  This allows for the effective placement of very fine pitch components including, in some cases, bare die-attach.  Additionally, the low CTE materials will facilitate the alignment of multiple layers and the features they represent in a complex PCB Layout.
Features
.CTEr = +40/+50 ppm per °C (low); Tg (glass transition temperature) is 280°C
.ER = 3.38/3.48 at 10.0 GHz
.ER is constant to 40.0 GHz
.ED (electro-deposited) copper only
.Layer-to-layer thickness control = +/- 0.001
.Fabrication costs are typical to slightly increased
