Depending on the micro switch, mechanical keyboards can be divided into many types, such as the traditional brown axis, blue axis, white axis, black axis, red axis, as well as Romer-G and optical axis.Therefore, this is the choice aula mechanical keyboard The reason, there is no denying its positive impact. https://www.aulastar.com/

　　What is a mechanical keyboard and how does it work?

　　Working Principle:

　　Physical Mechanical Switch: The working principle of mechanical keyboard is to achieve key triggering and feedback through physical mechanical switches. Each key is equipped with an independent mechanical switch, which consists of a spring and a switch.

　　Key Trigger: When the key is pressed, the spring is compressed and the switch is switched, triggering the action of the key. This physical triggering method makes the triggering of mechanical keyboards more reliable and direct.

　　Triggering force and triggering point: Each mechanical switch has a specific triggering force and triggering point. This means that the user needs to press a certain force to trigger the switch, and at a certain point in the key travel, the switch will complete the triggering action. This design allows users to choose different types of switches according to their preferences and needs to get the best feel and feedback.

　　Durability: Each mechanical switch has an estimated lifespan, and usually fails after hundreds of thousands or even millions of key presses. This makes mechanical keyboards more durable than other types of keyboards and the first choice for many professional users and gamers.

Each mechanical switch usually has a long service life and usually fails after hundreds of thousands or even millions of keystrokes. Therefore, mechanical keyboards are often considered the first choice by professional users and gamers.

　　Mold accessories are mainly parts or components installed on the mold. They can be widely used in various plastic molds, stamping molds, automobiles, electrical and aviation manufacturing fields. However, for mold accessories, the better the quality, the longer the life. Therefore, it is a problem that we all pay close attention to to understand the factors that affect the quality of mold accessories. Do you know what factors affect the quality of mold accessories? Hairong Precision introduces you below:As a representative of the industry, plastic mould part manufacturer It is necessary to set a certain example for peers and lead the way in product quality. https://www.dghrjmmj.com

　　The factors that affect the quality of mold accessories are as follows:

　　1. Rationality of mold accessory design

　　Mold accessory designers should first fully understand the user’s use requirements and working conditions, and the situation of die-casting force, and then select suitable materials according to the use requirements and working environment, and understand the die-casting performance of the materials. In the design of mold accessories, special attention should be paid to the premise of meeting the use requirements, and the die-casting structure should be as simple as possible. The wall thickness should be appropriately uniform, and the necessary mold slope should be left, otherwise it will cause pits, pores, shrinkage, underpressure, stretch marks, cracks, deformation and other defects on the casting. The requirements for the dimensional accuracy of the casting should be reasonable, otherwise it will bring unnecessary troubles to the mold design, mold processing, process condition formulation and management, and will cause a large number of unqualified products.

　　2. Mold structure, processing accuracy and mold material

　　The selection of mold accessories for die casting is closely related to the product quality of die casting, mold design, processing, mold material selection, etc. If the mold structure is unreasonable, it is difficult for mold accessories to make the product qualified no matter what measures are taken from the process. In addition, the mold material, mold processing accuracy, surface roughness, processing marks, small cracks in heat treatment, nitride layer thickness and mold assembly of heat-resistant and wear-resistant mold accessories will affect product quality and mold life.

　　3. Shrinkage rate of mold accessories

　　The shrinkage rate of casting materials is generally expressed as an average percentage or a percentage of a certain range of variation. The average shrinkage rate of the material is usually selected. For the design of high-precision die castings and molds of mold accessories, special attention should be paid to the selection of material shrinkage. If necessary, the mold can be tested first, the required data can be obtained in the test mold, and then the production quantity of large molds designed and manufactured can be carried out.

　　To sum up, these are the factors that affect the quality of mold accessories. In order to better ensure the quality of mold accessories, we try to choose the best structural solution in the design process. The designer of mold accessories must fully consider the technical requirements and structure of the parts, and must meet the processability and feasibility of mold manufacturing.

　　Recently, market research firm LightCounting (hereinafter referred to as LC) released a new report on the theme of “Optics for Artificial Intelligence”. The report points out that artificial intelligence has emerged in the blink of an eye. LC’s first “Optics for Artificial Intelligence” report emphasizes how artificial intelligence is changing computer architecture and networks, and optics plays a key role in this. LC’s artificial intelligence predictions focus on optics. However, the agency said that if there is one more prediction, it is: not only will optics play an important role in the development of artificial intelligence systems, but artificial intelligence will increasingly contribute to the design of these systems at the transistor, chip and system levels.with 800g qsfp-dd For example, if it continues to develop, it will definitely become the benchmark of the industry and play an important role in leading the market. https://www.3coptics.com/

　　optical technology

　　The pace of innovation varies across industries. New applications are developed at a rapid pace. Most of them will fail, but some will succeed and seemingly change the world overnight. Software and AI algorithms are being innovated faster than we can imagine. At least that¨s what it seems to be to outside observers, but experts may not see it that way.

　　Innovation in the hardware space is a more gradual but relentless process. Optical connectivity is no exception, and there is solid data to support this. The adoption of silicon photonics has taken a decade, waiting for the technology to bring truly disruptive solutions, such as reliable co-packaged optics. This will undoubtedly happen by the end of this decade, but the forecasts in this report focus on pluggable optical modules deployed in AI clusters – the dominant solution for optical connectivity today and over the next five years.

　　Currently, more than 90% of optical modules deployed in AI clusters are used for InfiniBand and Ethernet connections. As shown in the figure below, the bandwidth required for NVLink to connect to GPUs is 4 times that of Ethernet and InfiniBand. Another bottleneck in AI cluster design is the limited high-bandwidth memory (HBM) available to GPUs, which is another factor in the 3x bandwidth increase.

　　optical technology

　　It turns out that optical switches can be used to scale and reconfigure its AI clusters to improve cluster performance while minimizing cost and power consumption. The research firm expects more companies to adopt this technology in the next 3-5 years.

　　The scale of optical demand for applications in AI clusters is a pleasant surprise in 2023, and the timing of ChatGTP making headlines in late 2022 is particularly significant. Fears of an impending recession and initial signs of declining revenue growth have forced all leading cloud companies to cut spending, including investments in data centers and purchases of optical modules. Strong growth in 2024-2025 is unquestionable.

　　The growth of business from large network equipment manufacturers is the main factor affecting the sales volume of optical modules in 2023-2025. New designs for AI clusters require more optical modules. All previous systems used only InfiniBand networks for optical connections, and most of these systems were AOCs. The latest systems based on NDR (400G) InfiniBand use pluggable 400/800G SR4/SR8 and DR4/DR8 optical modules instead of AOCs. The company also released an NVLink chassis switch designed for 800G optical connections in March 2022. The company is currently testing optical fiber NVLink internally, but these solutions should be available to end users by the end of 2024. If it takes longer, LC said it will have to lower its forecast for 2025-2029.
