PCB city information
The semi-cured sheet, also known as "PP sheet", is one of the main materials in the production of multilayer board, which is mainly composed of resin and reinforcement materials. Most of the semi-cured sheets used in the production of multilayer circuit board are made of glass fiber cloth as reinforcement materials.

What is the perplexing problem in the traditional cutting process?
One
First, quality impact:
The main appearance requirements of the semi-cured sheet used for the multilayer board are: the cloth surface shall be flat, free of oil stain, stain, foreign impurities or other defects, free of cracks and excessive resin powder, but micro cracks are allowed. However, with the traditional cutting machine, there will be white, discount, wrinkle, carbonization and other phenomena on the edge. At the same time, a large number of dust and glass wire drawing will be generated, which will easily lead to the defects such as sags in the subsequent pressing process of the semi-cured sheet, and will also affect the quality of the circuit board products.
Two
Second, environmental pollution:
The fine dust produced by cutting is easy to float in the air, causing environmental pollution. After inhalation, the human body will deposit in the lungs, and a large amount of dust will be inhaled during long-term operation, which will seriously harm the health of workers. In addition, the dust particles are too small, easy to stimulate the skin, causing skin allergy and other symptoms.
Three
Third, it costs manpower:
This will also cause the workshop and equipment to accumulate too much dust in a short period of time, and need to spend a lot of manpower and material resources to clean up the dust every day, increasing the labor cost and production burden.
Cutting process and effect of traditional pure mechanical cutting machine:
In summary, this is an event triggered by "dust"!
Is there any good way to solve it?
Zhengye science and technology semi curing sheet dust-free automatic cutting machine these problems will be solved
▲ Zhengye technology semi curing sheet dust-free automatic cutting machine
01 innovative technology infrared heating changes cutting mode technically
Zhengye science and Technology Co., Ltd. adopts the method of combining infrared heating innovation technology with traditional mechanical cutting to soften the resin on the surface and inside of the semi-cured sheet and heat the semi-cured sheet before cutting, so as to reduce the equivalent of dust cutting and automatic edge sealing Therefore, it can make the cutting edge of the semi curing sheet neat, without powder, whiteness and scorch, and solve the problems of dust and burr caused by the crushing of small resin in the traditional pure mechanical cutting process that has been puzzling the industry for a long time.
Traditional mechanical cutting:
Zhengye dust free cutting:
02 equipped with high-efficiency dust suction device while cutting, so that there is no place for dust to escape
In addition to greatly reducing the dust on the cutting production source, the semi curing sheet dust-free automatic cutting machine has also added an efficient dust suction device, which can achieve cutting and suction, and the two pipes work together, so that a small amount of dust can not escape, and the overall cutting dust reduction rate of the equipment is more than 98%.
≫ & gt; & gt; & gt; & gt; I'm a little divider & lt; & lt; & lt; & lt; With the products of the same industry and other traditional products, Zhengye technology semi curing sheet dust-free automatic cutting machine has the leading advantages in cutting effect and dust reduction. At the same time, it also has outstanding cutting accuracy and efficiency. With advanced servo control system, the cutting accuracy is up to ± 1 Mm, dynamic heating for cross cutting and longitudinal cutting, no need for follow-up processing, cutting efficiency up to 21 cutter / min, one key automatic knife adjustment, PP sheet can be automatically stacked, and the overall technology has reached the leading level at home and abroad.
Zhengye technology semi curing sheet dust-free automatic cutting machine not only has the advantages of precision, high quality, high efficiency, low dust, health and environmental protection, but also realizes the technology upgrading in the original process, which can be adapted to the semi curing sheet automatic receiving machine, instead of the original manual receiving and finishing.
