The rod-in-tube (RIT) method is one of the conventional techniques used for optical fiber preform preparation. Interestingly, this term can also be found in other industries. In simple terms, it involves placing a glass rod inside a glass tube, heating the tube to melt it onto the rod, forming a thicker solid rod known as the optical fiber preform. Finally, one end of the preform is heated and stretched to form the optical fiber. RIT brings about various possibilities for specialty fiber development, and the tube-in-rod technique extends beyond the use in communication fibers. This technique enables more flexible fiber designs and paves the way for wider applications.

Since 2020, the global semiconductor industry has always occupied headlines, and the world has forced the world to stop working. At the same time, the impact of digitalization on life and enterprises is accelerating the development of unprecedented speeds. In turn, the semiconductor market has flourished. By 2021, sales will increase by more than 20%, and by 2021, it will reach approximately $ 600 billion. Many experts are convinced that the semiconductor industry is expected to achieve ten years of growth. By 2030, it is expected to become a trillion -dollar industry. However, it is not all good news. In fact, according to experts, the short -term prospects of semiconductor income have deteriorated. In essence, with the deterioration of the economic situation, it is inevitable that the supply is too demand. Both WSTS and Gartner's predictions show that the global semiconductor market will be dragged down in the memory semiconductor market next year. "In the latest forecast, this category is expected to fall to $ 112 billion by 2023, a 17%decrease compared to the previous year," WSTS said in its statement. In fact, Gartner believes that in the remaining time of 2022, the memory market will witness weak demand, inventory expansion, and significant reduction in prices. "Therefore, the memory market will remain stable in 2022, and it is expected that revenue in 2023 will drop by 16.2%," it said. WSTS predicts that Japan, the United States and Europe will grow in 2023, but it is expected that other regions of Asia -Pacific, including China, will decrease by 7.5%. China is the world's largest semiconductor market, accounting for more than 30%of the total. China's influence also means that the global semiconductor market may face a more serious decline in prediction than WSTS in 2023. (Semiconductor core, Techwireasia) Nanjing Hecho Technology Co., Ltd specializing in manufacture Fiber Optic Illuminator and Fiber Optic Bundle, which are widely used for Semiconductor optical inspection, OEM & ODM service is available.

ccording to the Taiwanese media "Economic Daily", statistics from relevant research institutions in Taiwan, China show that the world will set off a wave of fab expansion from 2022 to 2025, or 41 new fabs will be added. Among them, major factories such as TSMC, Samsung and Intel have invested in expanding production in the United States, and the total number of new additions in the United States has reached 9 at most. According to Knometa Research data, there are currently 452 fabs in the world, with 112 in Japan, the second in Taiwan, and the third in the United States and Canada. Among them, Asia accounted for nearly 70%, 12-inch factories were 41 in Taiwan, 25 in South Korea, 26 in Japan, and 19 in the United States. Due to the growth in demand for semiconductor applications and geopolitical factors, it is estimated that 41 fabs will be built around the world from 2022 to 2025. Data analysis shows that 32 factories are located in Asia in terms of total, and the expansion of 12-inch factories is the main one. China Taiwan is estimated to add 6 factories, including 4 12-inch, 8-inch and 1 below 6-inch; Japan is estimated to increase 7 factories, including 12-inch factories and 8-inch 1; China is estimated to increase 8 In addition, there are 9 new wafer fabs in the United States, which is the largest increase, including an estimated 8 new 12-inch fabs and 1 8-inch fab. Analysts said that related capacity expansion also produces more carbon emissions, and the semiconductor industry must also improve the problems of high power consumption and high carbon emissions. Hecho specializing in design and manufacture the Fiber Optic Bundle and Fiber Optic Illuminator, which are widely used for the Semiconductor optical detection field, including Automated Optical Inspection, PCB defect detection, and so on.

In ancient times, Greek glassblowers observed that glass rods could transmit light. In 1854, Tyndall of England pointed out in a lecture at the Royal Society that light could be transmitted by reflection along curved pipes containing water, and confirmed this idea with experiments. In 1870, British physicist Tyndall observed in his experiments that when light was irradiated into a container containing water, and water was poured out from the water outlet, the light also propagated along the water flow and appeared curved, which did not seem to conform to light. The law that only travels in straight lines. In fact, the light still travels in a straight line at this time, but there is a light reflection phenomenon in the water flow, so the light travels in a broken line. Light can also "take a detour". In 1927, Baird in the United Kingdom first used the phenomenon of total reflection of light to make quartz fibers for image analysis, and obtained two patents. In 1930, someone pulled out the quartz filament, and discussed the principle of its light transmission. In 1951, the Netherlands and the United Kingdom began to develop soft fiberscopes. In 1953, the Dutchman Van Hel painted a plastic with a refractive index of 1.47 on glass fiber to form a jacket with a lower refractive index than the core of the glass fiber, and obtained a glass fiber with total reflection (insulation) of light. However, due to the non-uniformity of the plastic jacket, the loss of light energy is too great. In 1955, the phenomenon of light reflecting and traveling in a curved pipe was practically applied. Dr. Kapani, who was working at the British College in London at the time, made optical fibres from extremely fine glass. Each filament-thin optical fiber is made of two glasses with different refractive indices, one glass forming the central beamline and the other being wrapped around the central beamline to form a cladding. Due to the difference in optical properties between the two types of glass, after the light enters from one end of the optical fiber at a certain angle, it will not escape from the fiber wall, but will continue to reflect along the interface of the two layers of glass and exit from the other end. Initially, this optical fiber was only used in medicine. An endoscope composed of optical fiber bundles could observe diseases in the human stomach and intestines, and assist doctors to make accurate judgments in a timely manner. In fact, modern multi-mode optical fiber communication uses the principle of light reflection to limit the total reflection of light inside the optical fiber, and replace the electrical signal in the traditional communication method with optical signal to realize the transmission of information. Hecho is committed to the research and development and production of non-standard Fiber Optic Bundles, using high transmission efficiency optical fibers to make various optical fiber guide beams, which are widely used in in vitro diagnosis, biochemical analysis, optical detection, industrial automation, High Power Laser Fiber and other fields. Hecho has strong R&D and production capabilities, which can flexibly meet the differentiated needs of different customers.

In recent years, new display technologies have blossomed, and Mini LED has become the display technology that most color TV companies are deploying. It is generally believed that 2021 is the first year for the commercialization of Mini LED TVs. This year, Samsung launched the Neo QLED TV with Mini LED backlight technology, and Apple also launched the first iPad Pro with Mini LED backlight technology. Relevant survey data show that the global shipments of Mini LED backlight smart terminal products in 2021 will be about 3.92 million, and it is expected that by 2025, the data is expected to reach 16 million, with a compound annual growth rate of about 42.1%. Among them, Mini LED backlight TV shipments will be 1.6 million units in 2021, and it is expected that by 2025, the shipment scale will reach 9 million units. In addition, according to forecast data from DSCC, Mini LED panel shipments for tablet PCs are expected to grow by 80% by 2022. Mini LED backlight products have different process solutions on the manufacturing side. For example, in the selection of backplanes, different panel companies will have different choices. Some panel companies choose traditional PCB printed circuit boards as backplanes, while some panel companies choose glass substrates as Mini LED backplanes. So, what is the difference between the two options? Compared with the PCB substrate, the glass substrate has many advantages: the thermal conductivity of the PCB material is not as good as that of the glass, and when the number of LED chips increases, the service life of the LED will be reduced; the glass substrate has the characteristics of good flatness and low expansion and contraction coefficient, which can better support COB packaging of Mini LED chips, and when the thickness of the PCB board is less than 0.4mm, when the LED chip is packaged on the PCB substrate, due to the different thermal expansion coefficients of the packaging glue and the PCB material, there may be a problem of glue cracking; When used, the glass base can achieve a narrow frame and low OD value (the distance between the lower surface of the diffuser and the upper surface of the circuit board), so that the TV can be made thinner and more fashionable; the glass base can make the area of the backplane smaller as needed Large, infinite splicing can be achieved, while the PCB version is difficult to achieve; in addition, the cost of the glass substrate is relatively lower compared to the PCB substrate. Although the PCB substrate is relatively mature, there are many shortcomings in the field of Mini LED display, which is why Apple, Samsung and other giants are choosing glass-based Mini LED. In summary, the Mini LED TV market is in the ascendant, and glass-based has better application prospects than PCB-based. With the promotion of upstream companies and terminal giants, whether glass-based can replace PCB-based in the future deserves continuous attention. Nanjing Hecho Technology is committed to providing customers with optical transmission solutions. With strong R&D and production capabilities, it can provide high-brightness Light Source and various non-standard fiber bundle customization services, including AOI high uniformity for the glass substrate or PCB industry Linear Optical Fibers, etc., flexibly meet the differentiated needs of customers in different industries.

Fiber-coupled semiconductor laser structures mainly include single-tube coupled lasers, multi-single-tube coupled lasers, mini Bar and Bar/stacked array series. Multi-single-tube coupled lasers have become one of the mainstream pump sources for fiber lasers due to their high reliability. . As fiber lasers develop toward higher power, semiconductor lasers also develop toward high power and high brightness. With the development of industry, the laser power of semiconductor lasers has climbed to the kilowatt level, and it has applications and certain advantages in laser brazing, laser cladding, and laser metal welding. laser brazing Laser brazing has always been an advantageous application of high power semiconductor lasers. Although the energy density of semiconductor lasers is slightly lower than that of fiber lasers, the energy distribution is uniform, and the brazing wire melts uniformly and is not easy to generate spatter during the brazing process. Laser Cladding Laser cladding can improve the wear and corrosion resistance of metal parts. Laser cladding has a fast cooling rate and belongs to a rapid solidification process, and it is easy to obtain a fine-grained structure or a new phase that cannot be obtained in an equilibrium state, such as an unstable phase and an amorphous state. At the same time, the coating dilution rate is low, and it has a strong metallurgical bond or interface diffusion bond with the substrate. By adjusting the laser process parameters, a good coating with a low dilution rate can be obtained, and the composition and dilution of the coating are controllable. At the same time, the heat input and distortion of laser cladding are small, especially when fast cladding with high power density is used, the deformation can be reduced to within the assembly tolerance of the part. Laser Metal Welding High-power semiconductor lasers have high welding strength during tailor welding, and the welds are smooth and flat without post-processing, and are widely used in automobiles, metallurgy, national defense and military industries. Advances in high-power semiconductor lasers have enabled many important applications. The STFB series semiconductor lasers provided by Xinte Optoelectronics are smaller in size, higher in power and brightness. This small-sized semiconductor laser has a smaller shape and can also reduce the consumption cost of materials. Fiber-coupled semiconductor lasers with coupling efficiencies over 90% can be fabricated using simple optical components. With cost and performance improving more than 10 times every decade, high-power semiconductor lasers have disrupted the market in unforeseen ways. While it is difficult to predict future applications with precision, a lot can be enlightened by looking back at the past three decades to conceive of the possibilities of the next decade. Nanjing Hecho Technology focuses on the research and development and production of various laser fibers, which can meet the transmission needs of various high-power and high-energy lasers in industry, medical, scientific research, aerospace, etc., such as Plastic laser welding, LDI laser direct imaging in PCB field, holmium laser and energy-transmitting medical fibers, etc. . Hecho Technology provides customized services for customers in different industries, and flexibly meets the differentiated needs of different customers.
