[PConline stand-alone evaluation] If there is such a product, we say it has the most characteristic of a place, everyone knows when it is, then this product is undoubtedly a success. In my opinion, today's product is the most widely recognized and influential series of all notebooks - "Little Red Dot."
Lenovo ThinkPad X1 Carbon 2017(20HRA007CD) Reference Price: Loading... Image Reviews Price Quotes Overview
In terms of product positioning, X1 is undoubtedly the highest-end product line of ThinkPad, and the latest generation of X1 Carbon is the flagship model of ThinkPad's traditional ultrabook. In the business area, the ThinkPad has always played an important role. As a fifth-generation product, what has changed in the ThinkPad X1 Carbon?
ThinkPad or ThinkPadFor such a classic product, the appearance of the inheritance is undoubtedly very important, regardless of the first generation of products must retain the most classic design, which also used the old product people a kind feeling. The appearance and previous product changes of the ThinkPad X1 Carbon 2017 were not as significant.
Carbon fiber A surface, can give people the greatest degree of comfort touch, but the price paid for this is a handprint. The ThinkPad logo, still in the upper left corner, is still in the Lenovo Logo in the lower right corner. These are telling people that regardless of the first generation of products, the ThinkPad or the ThinkPad.
Speaking of the features of the ThinkPad, that is the iconic little red dot, it will still be in the middle of the GHB three keys regardless of the first generation of the product. The feel of the keyboard is still very good. The keyboard with the silent metal shrapnel has no change in touch, but it makes the sound quiet. Two-level adjustable backlight keyboard is also very bright, light white light is also in line with business positioning.
In terms of interfaces, the ThinkPad X1 Carbon 2017 is still very good. The left side of the fuselage has two Type-C interfaces, a USB 3.0 interface, HDMI interface and a mini-RJ45 interface, on the right side of the fuselage is to support the shutdown charging USB 3.0 interface and a headset microphone combo interface.
To come up with it alone, this generation of SD card readers is located behind the entire notebook. In the position where the screen and keyboard are connected, it is easy to miss if you do not pay attention.
Although the appearance of the ThinkPad has always been the style, and once we open the top cover, you can find the biggest change in this generation of X1 Carbon. The latest ThinkPad X1 Carbon 2017 features a narrow bezel design with 5mm on the left and right sides and 9mm on the top. And at the press conference, Lenovo also specifically emphasized that the ThinkPad X1 Carbon 2017's narrow bezel is designed without sacrificing strength.
Although it is a narrow border, the camera and microphone are still above the screen and they should have belonged there. When people use the camera, they will subconsciously look to the top of the screen, so no double chin, nostrils, etc. will appear during the video. The microphone is also just in parallel with the mouth to ensure a perfect radio effect.
In terms of keyboard layout, the ThinkPad X1 Carbon 2017 has also made some changes. In order to be more convenient for people, F8-F12 has added new shortcuts for function keys, namely, WiFi switch, Windows control panel, Bluetooth switch, keyboard setting page, and custom function keys.
The location of the vents is also different from that of the previous generation. This generation of ThinkPad X1 Carbon 2017 does not use the previous generation of hinged shafts but instead uses sunken shafts. Therefore, the rear air outlet is changed to the right side of the fuselage, which is more conducive to the heat dissipation of a notebook such as the X1 Carbon. The only drawback is that the hot air blown from the right outlet after a long period of use may blow into the hands.
For users with screen size requirements, you can also purchase the monitor separately, use the Type-C interface as the connector, have a better transmission speed, 99% sRGB accurate reduction of subtle colors, and then with the 4.4 mm border, whether it is entertainment or Work can make the experience even more perfect.
In addition to improving the visual effects of the narrow frame, or the size of the entire body has become smaller, and now the body size is 323.5 mm * 217.1 mm * 15.95 mm, compared to the previous generation, almost 1 cm in length and width. In terms of weight, the body weight is 1.115Kg and the travel weight is 1.459Kg, which is still excellent.
In terms of hardware, the ThinkPad X1 Carbon 2017 did not bring much surprises to everyone. The one in my hands was an Intel Core i5-7200U, 8GB of RAM, and 256GB SSD. For business, this is a very standard configuration. Here I also found several commonly used running software to test this notebook.
â– CineBench R15
CineBench is a very convincing set of CPU and graphics test systems, the latest is the R15 version. Compared to up to 16 cores in R11.5, the R15 version can support up to 256 logic cores. In addition, the new version also enhances the investigation of shaders, anti-aliasing, shadows, lights, and reflection blur, and the performance of CPUs. The test is more accurate.
â– 3DMark
3Dmark is a futuremark company's software designed to measure the performance of graphics cards. The 3Dmark developed to the present is not only a software to measure the performance of graphics cards, but it has gradually become a software that measures the performance of the whole machine.
â– AS SSD
AS SSD Benchmark is an SSD test software from Germany that can test continuous read and write, 4K alignment, 4KB random read and write and response time performance, and give a comprehensive score. At the same time, the software also comes with the Compression Benchmark project, which can give a curve describing the transformation of performance as the compressible data occupancy (compression ratio) in the data model increases.
â– Office software
For such a business book, only running sub data is always weak. I used to buy business, of course, is for office, ah, this time I chose the office software to test the ThinkPad X1 Carbon 2017. After opening 10 PPTs and 10 WORDs in one breath, the CPU occupancy rate is about 20%, and the visible performance is still very strong.
â– Life
Life is undoubtedly the most important for a business book. The ThinkPad X1 Carbon 2017's battery life is really powerful. It starts at 1:10 pm. In the case of 100% brightness, the backlight level of the keyboard backlight is used continuously for three and a half hours. There is still 50%.
Editor's summary: The fifth-generation X1 Carbon 2017 has a very high level of performance and storage space. It can be said that this ThinkPad is at the top of the business book. It is safe, stable, high-performance, long-lasting, and easy to carry. It will push it to a higher status. ThinkPad is a rare partner for business people. It is even a belief for the first batch of users who use notebook products. A high-performance ThinkPad is a product that can accompany you for a long time.
PCB Prototype
Cheap PCB Prototype - Manufacturing And Assembly Services
What is PCB prototype and why it should be used
PCB prototype refers to the trial production of printed circuit boards before mass production. After the electronic engineer designs the circuit and completes PCB Layout, the PCB gerber file, etc. is provided to the PCB manufacturer for small batch trial production. The purpose is to verify the correctness of the design and to test individual functions.
The number of PCB prototypes is usually not specified. It may be one piece, ten pieces or other numbers.
After confirming that PCB prototype production and testing are all right, small and medium batch production and mass production can be carried out and electronic products can be put into the market.
PCB prototype manufacturing can be divided into two ways: regular PCB circuit board factory and professional PCB prototype manufacturing company.
Regular factories produce PCB prototypes in order to have batch orders, so of course they want to return orders; PCB prototype manufacturers themselves only do prototypes or small batches, if there is a batch orders generally can not do.
In terms of quality assurance, it is certain that regular factories do better than PCB prototype manufacturing companies. Prototype manufacturing companies are One-Hammer Business. After prototype production is completed, prototype will be sent to you, and then payment will be received. they will not normally carry out flying probe testing. If the quality is not up to you, you have to retake it. Regular factories generally do flying needle testing, from material to process are meticulous and professional, so the quality is often successful once.
A PCB project involves a lot of things, if a product has problems in a certain link, it will easily affect the product development progress; PCB board making is also the same, generally a project, designed PCB will go to prototype manufacturing, do a few boards for testing, if the test passes, all OK, then you can find batch manufacturers in the future. Direct mass production, the price will be much lower than the prototype manufacturer, prototype manufacturer prototype production is mainly highlighted fast.
What are the benefits of PCB prototypes?
Before mass production, we recommend that you use PCB prototype design services for functional testing of new products. The benefits of developing PCB board prototypes include:
If there are any errors, quickly test and correct the design - after waiting more than a week for the board, you will be anxious to get them into your application. You can do this when you pre-test your design with a PCB prototype.
Detection of any early potential design defects-PCB prototype design service allows you to discover any design problems within a few days and correct design errors in time before putting them into production.
Order a small amount of production, MOQ only has five boards if necessary - save money and reduce risk by delaying large orders until you know you have the type of sheet you need.
Benefit from lower production tolerances - It offers a clear indication of how well your PCB will perform
Once the prototype board can meet your quality and performance requirements, you can carry out comprehensive production. Then, we will transition from PCB prototype board service to standard PCB manufacturing service, providing stricter production tolerances and more advanced options, including free manufacturing design (DFM) checks, to detect potential problems that may reduce the quality of PCB.
While it may be tempting to simply order your full printed circuit boards and decide you`ll deal with any design flaws that arise as they come, it`s rarely the most efficient solution. You may get the boards out sooner, but if something goes wrong, it could prove to be a lot costlier and more time-consuming than taking an extra few days to test a prototype.
