Laser welding is a welding method that uses a high-energy-density laser beam as a heat source, that is, laser radiation heats the surface of the workpiece, and the surface heat diffuses into the interior through heat conduction to melt the workpiece and form a specific molten pool. The laser beam passes through the upper layer of light-transmitting material, and then is absorbed by the lower layer material, and the laser energy is absorbed and converted into heat energy, since the two layers of materials are pressed together. Thermal energy is conducted from the absorbing layer to the light-transmitting layer, causing the two layers of material to melt and bond.

It can be seen that the energy of the laser beam must be absorbed by the plastic to achieve a good welding effect, so the CO2 laser is generally used for plastic laser welding. Also, not all plastics can be welded with laser welding. Plastics can be divided into thermoset and thermoplastic. Among them, thermosetting plastics are not reproducible and cannot be welded, while thermoplastics will melt after reheating (you can use heating and cooling to make them reversible), which is a so-called physical change, so it has weldability.

Compared with other welding methods, laser welding has the characteristics of high speed and good effect. way to weld complex parts, such as plastics containing circuit boards. Industries such as automotive, medical, consumer electronics, and food are ideal application areas for laser welding.

1. Automotive industry

Plastic laser welding machines are widely used in the automotive industry, such as automatic door locks, engine sensors, cab racks, fuel nozzles, gear shift racks, etc. Some models have also used laser welding for taillights.

2. Medical field

Plastic laser welding machines can be used to manufacture liquid storage tanks, liquid filtering equipment, hose connectors, ostomy bags, hearing aids, implants, microfluidic devices for analysis, and more.

3. Packaging industry

For example, the packaging of advanced industrial products, using plastic film welding technology, can obtain plastic packaging with high processing speed, reliable seams and beautiful appearance. Laser welding connection of plastic outer packaging material. Plastic materials are thermoplastics and elastomers.

Laser welding plastics has the comprehensive advantages of low cost, no pollution, high speed, convenient processing, easy realization of precise numerical control, wide application range of raw materials, good bonding and manufacturability. The application of plastic laser welding will become more and more extensive, and the technology will become more and more mature. In order to meet the growing demand for transparent plastic products in the industrial, medical and scientific research markets, Nanjing Hecho Technology provides various customized High-energy Transmission Optical Fiber for the laser plastic welding industry, with high transmittance, good uniformity, and high-energy transmission. Advantages, widely praised by the market.

Arrayed fibers are a special type of fiber structure composed of multiple individual fiber bundles arranged together in an array. Each individual fiber bundle has its own transmission channel and can independently transmit optical signals.

Arrayed fibers play important roles in many applications:

Fiber Optic Sensing: Arrayed fibers can be used as building units for fiber optic sensors. By using multiple fiber bundles, it is possible to simultaneously monitor and measure physical quantities at multiple locations, such as temperature, strain, pressure, etc. Arrayed fiber sensors have the advantage of high sensitivity and multi-channel measurement.

Medical Field: Arrayed fibers find widespread use in medical imaging and diagnosis. They can be used to construct high-resolution fiber optic coherence tomography (OCT) systems and fiber optic microscopes for real-time observation and diagnosis of tissue and cellular structures.

Industrial and Scientific Applications: In industrial and scientific research fields, arrayed fibers can be used for applications such as spectroscopy analysis, laser processing, and optical measurements. Arrayed fibers with multiple channels can provide a larger sampling range and higher data processing capability.

What is biochemical analysis? 

Biochemical analysis refers to the detection method of enzymes, carbohydrates, lipids, protein and non-protein nitrogen, inorganic elements, liver function and other indicators in the body through various biochemical reactions. It is mainly used in routine testing in hospitals. 

Biochemical diagnosis developed earlier in my country and is a routine diagnostic testing item in hospitals, focusing on disease monitoring that has already occurred. 

At present, the domestic biochemical diagnostic reagent market is relatively mature, with a complete range of reagents. Domestic brands have occupied about two-thirds of the domestic biochemical diagnostic reagent market by virtue of the advantages of cost-effective products and high-quality market services. 

What is an immunoassay? 

Immunoassay is a highly selective diagnostic method established by using the specific reaction between the substance to be tested and its corresponding substance. It is often detected by the immune reaction of antigen and antibody, and various carriers are used to amplify the reaction signal to enhance the detection. Sensitivity (labels include isotopes, enzymes, chemiluminescence substances), including radioimmunity, enzyme-linked immunity,  chemiluminescence, etc., mainly to test small molecular proteins, hormones, fatty acids, drugs and other substances in the body, commonly used in infectious diseases, endocrine Detection of protein targets such as diseases, tumors, pregnancy tests, blood group antigens, etc. 

At present, high-end chemiluminescence has gradually replaced ELISA as the mainstream immunodiagnostic method in my country, focusing on the monitoring of infected diseases. 

ELISA: ELISA markers are enzymes, which are often used to detect an antigen or antibody. Reagents have the characteristics of low cost and large-scale operation, and are currently the mainstream of domestic immunodiagnostic reagents. 

Chemiluminescence: Chemiluminescence reagents have high sensitivity, strong specificity, and good reproducibility. They can be used for highly automated semi-quantitative and quantitative analysis, and have fast detection time and good reproducibility. It is one of the important development directions of immunological reagents.

 According to a recent report by Congic Business Intelligence, the global market for medical laser fibers is expected to grow significantly at a compound annual growth rate of 6.9% from 2023 to 2030. This growth is attributed to the increasing popularity of minimally invasive surgeries worldwide.

China's laser industry is developing rapidly and has obvious competitive advantages. The proportion of the global laser market has also continued to increase. In 2020, the scale of China's laser market will reach US$10.91 billion, accounting for 66.12% of the global laser market. It is expected to reach $14.74 billion in 2022.

Due to the excellent performance and strong applicability of fiber lasers, the market share has increased rapidly in the past decade. The market accounts for more than half of the market, and it has a clear leading position compared to solid-state lasers, gas lasers, and semiconductor lasers. The four major development trends are as follows:

Core components such as semiconductor laser chips are gradually being localized

Taking fiber lasers as an example, the pump source of high-power fiber lasers is the main application field of semiconductor lasers, and high-power semiconductor laser chips and modules are important components of fiber lasers. In recent years, China's fiber laser industry has been in a stage of rapid growth, and the degree of localization has increased year by year. In terms of market penetration rate, in the low-power fiber laser market, the domestic laser market share is as high as 99.01%; in the medium-power fiber laser market, the domestic laser penetration rate has maintained a level of more than 50% in recent years; the localization of high-power fiber lasers The process is also gradually advancing, reaching a penetration rate of 55.56%. However, core components such as high-power semiconductor laser chips still rely on imports. The upstream components of lasers with semiconductor laser chips as the core are gradually being localized. On the one hand, the market scale of domestic upstream components of lasers is increased. The localization of core components can improve the ability of domestic laser manufacturers to participate in international competition.

Recently, there has been a lot of discussion about silicon wafers. Here we analyze it from several perspectives:

First of all, in terms of demand, thanks to the rise of new applications such as 5G, artificial intelligence (AI), and electric vehicles, the demand for semiconductors has increased significantly, and the shortage of chips and the expansion of foundry production have continued to benefit, and the industry market is hot. According to the statistics of the International Semiconductor Industry Association (SEMI), the global semiconductor silicon wafer shipment area will continue to grow until 2024, and show a new high performance year by year.

The huge increase in demand for silicon wafers is related to the large-scale expansion of global wafer factories in recent years. According to SEMI statistics, the number of global semiconductor factories in 2019 was 957, and it is expected to grow to 1,011 in 2022. The monthly production capacity of the factory often jumps from 30,000 to 50,000 pieces. Silicon wafers have become an indispensable strategic material, and their usage will inevitably rise in a straight line.

On the other hand, assessed from the supply side, SEMI expects global silicon wafer shipments to hit a record high year by year in the next three years. Silicon wafer manufacturers at home and abroad are unanimously optimistic about the market. After all, the foundry capacity is full, and it is undoubtedly the strongest and powerful backing for the silicon wafer industry, which is the most critical upstream raw material.

The Optical Fiber Bundles and Light Sources produced by Hecho Technology are widely used in the semiconductor industry, such as wafer inspection, cutting, Laser Direct Imaging, Automatic Optical Inspection and other fields. Different needs of different customers.
