PCB substrate materials mainly include ceramic
substrates, resin substrates, and metal or metal matrix composite materials.
Compared with metal and resin substrates, ceramic substrates have outstanding
electrical insulation properties, excellent high-frequency characteristics, and
better Excellent thermal conductivity, thermal expansion rate, compatibility
with various electronic components, stable chemical properties, etc., are more
and more widely used in the field of substrates. Ceramic substrate products are
divided into Bare Ceramic Substrate and Metallized Ceramic Substrate according
to the production process. They are widely used as substrate materials for
different thick films, thin films, and circuits. They can also be used as
insulators, as heat conduction paths and in circuits with demanding thermal
performance. Used to manufacture various electronic components.
We have been producing a variety of advanced ceramic substrates for many years and have extensive manufacturing experience in Al2O3, AlN and Si3N4 materials.If customers have high precision requirements or edge processing requirements for substrate products, we can meet various requirements for size, thickness, shape and surface finish through fine grinding, polishing, laser scribing, and laser cutting processes.

(1) Low level of research and development. There is still a gap between the R&D of Chinese enterprises and foreign companies. At the same time, there is also a lack of a close coordination mechanism between scientific research units and enterprises. The effect of scientific research cannot be completed quickly. The government's investment in the development of environmental science instruments and dangerous investments are also lacking.
(2) The operating system of the company is not perfect, and the tendency toward dissimilation is significant. In detail, the operating mechanism of large-scale state-owned enterprises is now problematic, and they cannot play a good role in the main role; many small and medium-sized enterprises are surrounded by the lack of skills, lack of funds, and low levels of repetition, and the quality and performance of the instrument cannot be compared with foreign export instruments. confrontation.
(3) The product structure is irrational. The lack of high-tech products, the oversupply of high-end products, and the conflict between supply and demand cannot meet the strict environmental management needs. At present, the environmental monitoring apparatus industry has a small scope, backwardness in skills, and disorderly competition, especially in the areas of unstable technical performance and high level of set-up. This has led to the oversupply of high-end and high-end products, as well as high-quality and high-performance environmental protection instruments. There is no consumption, and most of them rely on exports.
China's environmental protection instrumentation problems
With the increasing market demand for environmental protection instruments and meters, the environmental monitoring instruments and meters consumed in China are mostly medium-to-high-end products. The products have many functions, high failure rates, low added value, and far from satisfactory in terms of type and quantity. demand. There are also problems such as low monitoring frequency, large sampling error, and incorrect monitoring data. These problems not only affect the scientific decision-making of environmental management and the solemnity of law enforcement, but also injure enterprise management to purify and protect the environment. High-quality analyzers, special-purpose monitoring instruments, and active monitoring systems are mostly imported from abroad, and domestic equipment accounts for a small share. The reason why such a situation is formed in the future is that there are several important causes:
