With the help of hot metal, Thunderbird released a more youthful I49-UI. This TV is equipped with a 49-inch 4K ultra-high-definition screen. Its fineness PPI is higher than that of the I55-UI. How exactly is it? Let's look down together.
Outstanding appearance: integrated body / metal narrow border
From the overall design, the I49-UI and the I55-UI have not changed much. The design of the integrated body design, the metal narrow frame, and the hollow base have been inherited. Although the I49-UI positioning is even younger, the appearance of the work is No shrinkage was found in other areas.
The front of this 4K ultra-high-definition screen supports 4 times the SDR color space, more precise control of the color, the display has been fully guaranteed.
The screen frame uses a high-strength metal material, and the gray coating is brushed to make it introverted without losing texture.
The black border of the screen is also in place. It is almost negligible to watch TV from the normal distance. Compared to other TVs with similar prices, this must be praised!
"FFALCON" at the bottom of the screen is Thunderbird's English name Logo. The letters are very delicate. Although they are relatively small, they feel the atmosphere.
Hollow bases have a great sense of design. No matter where they are in the home, they can enhance the beauty of home improvement. Metal material with excellent sandblasting technology, both the texture brought by the metal, but also the "temperature" brought by sandblasting.
The use of a hidden tapped hole on the back of the device resulted in this highly acclaimed integrated backplane design. It was not able to see a single screw hole, smooth and straight lines, outlined a diamond-shaped section, and the lines were relatively tough. The aluminum under the logo was The design of the alloy bars is very deflating for the entire back.
A row of holes hidden under the bars is used to dissipate heat. After you have got your hands, do not block the holes for dust protection.
The richness of the TV interface is an important basis for many consumers to consider whether a TV is worth buying. Thunderbird TV I49-UI's back interface from top to bottom are:
Digital audio output
Wired network input interface
Three HDMI high-definition input connectors
USB2.0 interface
Antenna input interface
AV input interface
These interfaces can be adapted to almost any usage scenario and are very practical without the need to purchase additional expansion accessories.
It must be mentioned that the Thunderbird is trying to avoid wiring too much, causing chaos. The back design groove of Thunderbird TV I49-UI also comes standard with a wire cover. After the cover is covered, the back is more clean and integrated. The most vivid expression.
In order to facilitate the user's daily data transmission, the back of the fuselage at the lower left corner also put a USB2.0 interface, U disk and ordinary hard disk can be competent. The round button is the power button. There is no problem with the actual test station blindly operating the switch in front of the TV. Normally, the switch TV can be switched on the remote control only, and the frequency of use is very low.
The remote controller is very simple in design, setting keys, power button, arrow keys, OK button, home button, menu button, return button, and volume button are all available. There is almost no learning cost. The matte texture of the plastic material provides a good touch. Digital Jun wants to say something special here. Some manufacturers' TV remotes have been made of metal materials. The appearance looks good and the texture is very strong, but in the winter... that sour, you know... So Thunderbird’s choice is more humane. Not designed for design.
Smart Voice: 100% recognition rate
Compared to the mechanical operation of the buttons on the remote control, voice control is more scientific and more convenient. Thunderbird's intelligent voice system can be started quickly with a remote control with a voice key (need to purchase it separately).
With some simple voice commands, you can achieve the desired operation, much faster than pressing a key. You can directly search for and play a well-known movie, or a certain episode of a popular TV show, and you can even fast-forward or rewind. This kind of time control is more accurate than the long-pressing of the arrow keys. The keys are purely luck. In addition to these open support applications, open the game, view the weather, check the stock movements and more.
The voice remote control function carried by Thunderbird has been optimized in depth for the domestic user's usage habits. It also understands Chinese, and has also done a lot of optimization in conjunction with the spoken language context of Mandarin. It is very smart, and the recognition rate can be 100%! Thunderbirds have shown enough effort in this regard.
Sharp image quality: 4K resolution/HDR technology/QUHD turbo technology
For television, the most important thing is of course the screen! Thunderbird TV I49-UI equipped with a true 4K ultra HD resolution screen, the same is 4K resolution, the smaller the screen size, the finer the screen will be higher, which is Thunderbird I49 compared to other larger screen 4K TV One of the advantages.
The screen itself supports 4 times the SDR color space, which makes the picture quality clearer and sharper and can present more details to the user. Hardware-supported HDR technology is more natural and realistic than software-based HDR. Thanks to the application of HDR technology, it is possible to make the screen with a larger light-dark range present more details. The dynamic HDR technology can be adjusted for different screens intelligently. The TV is always in the best display state.
It is also worth mentioning that the QUHD turbo technology adopted by Thunderbird TV I49-UI makes the dynamic brightness peak of the screen reach 450nit, and the dynamic contrast ratio reaches 120000:1. Even under strong light, it can be clearly given to the screen. All the details. In order to adapt to the extreme use environment of strong light and low light, Thunderbird TV I49-UI has also added Light sensor technology to eradicate the contradictory body from the hardware that is not sharp enough during the day and soft enough at night.
Sound quality: Conchs Sound system / Dbx sound
The most used time for TV is “look†and “listenâ€. Thunderbird TV I49-UI has already solved the problem of “lookâ€. So what about “listeningâ€?
The Conchs Sound system integrated in the body is the key guarantee for the sound quality performance of the Thunderbird TV I49-UI. The use of inverted speaker design, so that the sound leveling is better, more natural sound. Coupled with the surround sound field surrounded by Dbx's sound processing technology, it's hard to imagine that this is just a TV's built-in effects to achieve the sound effects. According to the test results of Digital Jun, Dbx brings the same bass effect as high-pitched sounds. At the same time, its performance in the midrange vocals is even more satisfying. Whether it is a TV series or listening to music, it All of them can make the vocal anomaly clear, not only clear, but also the beauty of the sound. Thunderbird TV I49-UI reduces the distortion of the sound to a minimum, and it can be described as a high-pitched pluck, full midrange, and deep bass.
In addition to watching the TV's open space, we can also connect the mobile phone to the TV via Bluetooth and use the TV as a Bluetooth speaker. At this time, you can turn off the screen separately, which not only reduces power consumption, but also effectively reduces unnecessary eye fatigue.
FFUI: Strong Performance/Smooth Experience/Extreme Content
The fluency of the system and the richness of content are one of the most critical factors for consumers to purchase television. Thunderbird TV I49-UI is naturally not to be outdone in this regard! Its built-in FFUI has become an acclaimed interview.
The homepage design is relatively elegant, and the relative wise merchants have a variety of fancy colors. Thunderbird's FFUI is really low-key.
However, Thunderbird also prepared two replaceable wallpapers, which were more bold in color matching, a warm tone and a cool tone, and did not support custom wallpapers. It was the last adherence of Thunderbird to the understanding of “beautyâ€.
In addition to home page recommendations, Thunderbird FFUI also supports a variety of customizable content pages. Including film, VIP, applications, sports, games, education and other major categories. In the UI design, we still adhere to the visual design of the box, beautiful and easy to use. In actual use, various operations are very smooth.
In the system settings, there are four major categories: Display, Voice, Network, and System. There are many personalized settings to deal with the diverse needs of non-consumers. To specifically explain the two functions of smart loudness and smart brightness, FFUI can intelligently adjust the TV volume and screen brightness according to the ambient volume and ambient brightness detected by internal special hardware, not only reducing the user's cost of use, but also allowing more Many users experience the charm of technology.
In addition, Thunderbird hides an egg-type function in the settings. The Smart TV Medical Examination System version 2.0, this fault diagnosis system is divided into local diagnosis and remote diagnosis. Local diagnosis is mainly a system built-in some programs to intelligently deal with some of the current problems that may exist in the TV. When you encounter problems with local diagnosis, we can also carry out remote diagnosis, but you need to call the online after-sales customer service before using. Personnel, under normal circumstances, as long as the hardware is not damaged, software failures can be perfectly resolved through these two methods, have to say that Thunderbird's after-sales service is really intimate.
The video content mainly comes from the strategic cooperation of Tencent video. Nowadays, the popular TV dramas are almost all updated synchronously. TVB TV dramas have reached 205, and there are also 53 US TV dramas. These are all original originals with genuine licenses!
The movie resources are rich and the resources are as many as several thousand. The latest cinemas and classic nostalgia do not fall. Individuals like the “Top Rated†category. All kinds of good movies are here to ensure that they are not wasted in junk movies. Life, like it!
Other categories of resources are also available, and all kinds of people can find their favorite programs to order.
Because Tencent video won the NBA's domestic exclusive copyright, not only the NBA's high-definition live broadcasts, but also real-time query each team, the player's detailed data, for the fans to come, this is definitely a killer! What's more, finally you can see the highlights of Chinese commentary and Chinese subtitles! Fans, let me hear your cheers...
Although 4K resolution screens are rapidly gaining popularity, 4K resources are somewhat out of step. Thunderbird TV I49-UI has specially set up a 4K film zone. Currently, there are 798 ultra-high-definition movies available online. The amount of this resource can be said to be quite abundant. Thunderbird is very powerful!
In addition, it is important to emphasize that Thunderbird also has access to globally broadcast resources. The resources here are definitely the latest and hottest cinema movies, and the definition is undoubted. However, most of them are movie theaters, so the on-demand conference will Fees, but this cost is compared to the movie theater fare, which is unmatched price performance.
In terms of game performance, Digital Jun downloaded two more popular games as tests in the built-in application market. The performance of fluency and picture quality is very good, and the sound performance is very rare. However, due to the inherent defects of the remote control, only relatively simple video games can be played. If you want to play some games with high complexity on the TV, it is recommended to use a separate game controller.
the weather
Thunderbird TV I49-UI built-in K song application experience is better than many mobile phone application experience, which is the inherent advantage of the big screen. If there are frequent K songs, it is recommended that you buy a professional microphone.
In education, Thunderbird TV has built a variety of subjects ranging from children to high school. There are also many online video lessons. There are no knowledge points in the class. Go home and turn on the TV to listen more often and you will naturally understand these resources. Not only can you help students, but also parents can save a lot of tuition and worry less.
Summary: Cost-effective / small-sized or bedroom-specific
Thunderbird TV I49-UI equipped with a 49-inch screen is not large in today's smart TV industry, its product positioning is also 3,000 files, for the economy is not very well-off for small and medium-sized family or bedroom users, the larger screen will It is neither fish nor fowl, 49 is the best choice.

What is PCB SMT assembly?
Q1: What is SMT assembly?
A1: SMT, short for surface mount technology, refers to an assembly technology used to paste components (SMC, surface mount components or SMD, surface mount devices) through a series of SMT assembly equipment to expose the PCB (printing Circuit board).
Q2: What equipment is used in SMT assembly?
A2: Generally speaking, the following equipment is suitable for SMT assembly: solder paste printer, placement machine, reflow oven, AOI (automatic optical inspection) instrument, magnifying glass or microscope, etc.
Q3: What are the attributes of SMT assembly?
A3: Compared with traditional assembly technology, namely THT (Through Hole Technology), SMT assembly leads to higher assembly density, smaller volume, lighter product weight, higher reliability, and higher impact resistance , Lower defect rate, higher frequency, lower EMI (Electromag netic interference) and RF (radio frequency) interference, higher throughput, more automated access, lower cost, etc.
Q4: What is the difference between SMT assembly and THT assembly?
A4: SMT components are different from THT components in the following aspects:
a. Components used for THT components have longer leads than SMT components;
b. THT components need to be drilled on the bare circuit board, while SMT assembly is not required, because the SMC or SMD is directly mounted on the PCB;
c. Wave soldering is mainly used in THT assembly, while reflow soldering is mainly used in SMT assembly;
d. SMT assembly can be automated, while THT assembly only depends on manual operation;
e. The components used for THT components are heavy, high, and bulky, and SMC helps to reduce more space.
Q5: Why are SMT components widely used in the electronics manufacturing industry?
A5: First of all, current electronic products have been working hard to achieve miniaturization and light weight, which is difficult to achieve in THT assembly;
Secondly, in order to enable electronic products to be functionally integrated, IC (integrated circuit) components are fully utilized to a large extent to meet large-scale and high-integrity requirements, which is exactly what SMT assembly can do.
Q6: In which product areas are SMT components used?
A6: At present, SMT components have been applied to advanced electronic products, especially computer and telecommunications products. In addition, SMT components have been applied to products in various fields, including medical, automotive, telecommunications, industrial control, military, aerospace, etc.
Q7: What is the common manufacturing process for SMT assembly?
A7: SMT assembly procedures usually include solder paste printing, chip mounting, reflow soldering, AOI, X-ray inspection and rework. Perform a visual inspection after each step of the procedure.
Q8: What is solder paste printing and its role in SMT assembly?
A8: Solder paste printing refers to the process of printing solder paste on the pads on the PCB, so that the SMC or SMD can be stuck to the board through the left solder paste on the pads. Solder paste printing is achieved through the application of a template. There are many openings on the template, and the solder paste will remain on the pad.
Q9: What is chip mounting and its role in SMT assembly?
A9: Chip mounting contributes to the core meaning of SMT assembly. It refers to the process of quickly placing SMC or SMD on SMT components. The pad remains on the PCB pad. Therefore, based on the adhesive force of the solder paste, the components will temporarily stick to the surface of the circuit board.
Question 10: Why is the welding type used in the SMT assembly process?
A10: Reflow soldering is used in SMT assembly to permanently fix the components on the PCB, and it is carried out in a reflow soldering furnace with a temperature zone. In the process of reflow soldering, the solder paste is first melted in the first and second stages at a high temperature. As the temperature decreases, the solder paste will harden, so the components will be fixed on the corresponding pads on the PCB.
Q11: Do I need to clean the PCB after SMT assembly?
A11: The PCB assembled by SMT must be cleaned before leaving the workshop, because the surface of the assembled PCB may be covered by dust, residues after reflow soldering, such as flux, all of which will reduce the reliability of the product to a certain extent. Therefore, the assembled PCB must be cleaned before leaving the workshop.
Q12: What type of inspection is used for SMT assembly?
A12: In order to ensure the quality and performance of the assembled PCB, it is necessary to check during the entire SMT assembly process. Many types of inspections must be used to reveal manufacturing defects, which will reduce the reliability of the final product. Visual inspection is the most commonly used in SMT assembly. As a direct inspection method, visual inspection can be used to indicate some obvious physical errors, such as component displacement, missing components, or component irregularities. Visual inspection is not suitable for visual inspection, and some tools such as magnifying glass or microscope can also be used. In order to further point out the defects of the solder balls, AOI and X-ray inspection can be used after the soldering is completed.
Q13: What requirements must be met in the SMT assembly shop's terms?
A13: The basic requirements that the SMT workshop must meet are as follows:
Room temperature: 25 ±3°C (if temperature control equipment is not available);
Interior height of the room: 3 meters;
Room RH (relative humidity): 45% to 75% (if not available, humidity control equipment is required);
Static electricity requirement: 150KR±10% (need to be grounded by static electricity).
