Jialichuang successfully built domestic PCB CAM software, ensuring that key links can be controlled independently.

　　How important is the "localization" of industrial software? We have a deep feeling again in the recent big events.

　　The recently issued "Several Measures to Promote the High-quality Development of Software Industry in Shenzhen" also clearly pointed out that it is necessary to actively promote the high-quality development of software industry and "gather strength to attack core software".

　　As the mother of electronic products, PCB plays an important role in the manufacturing industry. As the core software in PCB manufacturing, PCB CAM software is widely used in various processes of PCB production, such as: production feasibility analysis, design data conversion and refinement processing, and providing production data (film, drill tape, gong tape, etc.) for each process.

　　However, a cruel reality is that such important industrial software has been monopolized by foreign countries for a long time, and the application ratio of foreign software such as Genesis2000, UCAM and CAM350 has reached more than 95%. In the complex international environment, "domestic substitution" is urgent!

　　How to build a PCB CAM industrial software with perfect functions and independent intellectual property rights? Perhaps, we can find the answer from the PCB CAM software recently launched by Jialichuang.

　　The key to "domestic substitution" needs a mature and easy-to-use software product.

　　As we all know, the replacement cost of industrial software is very high. In order to realize "domestic substitution" of PCB CAM software, the author believes that three basic conditions need to be met. First, the performance of the product should be strong and stable enough for CAM engineers and manufacturers to use it.

　　CAM software almost runs through the whole process of PCB production, which can be divided into three stages: one is the pre-production order quotation stage, and the production feasibility is analyzed and quoted through Gerber view and DFM function; The second is the engineering data processing stage, which transforms the customer’s design data into production data, and edits and modifies the design that may lead to bad, so as to improve the production yield; Third, in the manufacturing stage, because many different equipments will be used in each production process, it is necessary for CAM software to convert and be compatible with Gerber files, such as converting them into data formats required by LDI, drilling, milling and testing equipment, before production can be carried out.

　　Jialichuang’s recently launched industrial basic software-Jialichuang PCB CAM software just fills the gap in this field in China, which can be applied to the whole process of PCB manufacturing.

　　The author understands that Jialichuang’s PCB CAM software has been polished within its group for nearly ten years, and its stability and performance have been fully verified.

　　The second is the difficulty of operation. It is reported that Jialichuang CAM software is specially developed for domestic users and can meet the needs of domestic manufacturers. The all-Chinese operation interface is simple and easy to use, so users don’t have to worry about language problems. In addition, they also have a professional team to provide technical support. Compared with foreign software, the use threshold of this software is greatly reduced.

　　Finally, it is open. Tested by the author, this software supports Gerber, Gerber274X, PDF, DXF and other data formats, and has extremely powerful graphic editing function and analysis and inspection function. More crucially, the software allows users to carry out the secondary development of scripts, has good flexibility and expansibility, and can achieve a high degree of adaptation between the software and production equipment, processes and operators.

　　In the field of PCB CAM software monopolized by foreign countries all the year round, it is not easy to have such a domestic software with perfect functions to "break through".

　　From EDA to CAM software, why can Jialichuang write the story of "domestic substitution" again?

　　Years of industry accumulation provide rich soil for breeding industrial software.

　　Industrial software is related to the core competitiveness and systematic safety of China’s industrial chain, and it is a very difficult link. Excessive dependence on foreign software will not only lose the software market, but also face the risk of losing the initiative of industrial development and affecting the security of industrial information. The development of an industrial software requires the accumulation of technology and experience, but also takes time to verify, "fast is impossible."

　　Developing industrial software requires a strong industrial foundation. It has been 16 years since Jialichuang was established in 2006, and it is well-known in the industry. The main business covers the electronic and mechanical fields such as EDA software, PCB intelligent manufacturing, component mall, laser steel mesh, SMT patch and FA mechanical parts mall. Among them, PCB intelligent manufacturing includes various types such as large batch, small and medium batch and proofing, with tens of thousands of daily orders, and all orders adhere to self-operated manufacturing.

　　A large number of production requirements have prompted Jialichuang to build its own PCB CAM software. As early as ten years ago, they started layout and exploration. Orders and equipment of sufficient magnitude are also repeatedly verifying the reliability and stability of this software, and can update iterations in time according to the latest changes and production requirements of the domestic PCB industry. "The number of iterations of this software update is so much that we can’t remember it ourselves." The person in charge of Jialichuang CAM software said.

　　If the scale is huge and the orders are complete, it is the fertile ground for Jialichuang to cultivate PCB CAM software; Then, the supply of professionals is the "nectar" of the growth of this software. Independent research and development of industrial software requires professionals who know not only production and equipment, but also software, technology and algorithms, and such talents are rare.

　　Jialichuang’s current R&D team has more than 400 professionals, which provides a solid support for the development of industrial software. "A R&D team with professional talents, after ten years of polishing, has this mature product that can compete with foreign PCB industrial-grade CAM software."

　　The birth of an industrial software takes a lot of time and practice.

　　Sharing high-quality resources to ensure that the key links in PCB industry are self-controlled

　　Ni Guangnan, an academician of China Academy of Engineering, once publicly stated: "We are going to move from a manufacturing power to a manufacturing power. Without the support of industrial software, the transformation, upgrading and further development of traditional industries will face great problems."

　　For PCB manufacturers, foreign PCB CAM industrial software is expensive, with hundreds of thousands at every turn; Pirated software not only cannot realize customized design and secondary development of scripts, but also faces great legal risks. In recent years, the phenomenon of scientific and technological repression and blockade has constantly appeared in the international community, which has sounded the alarm for us: any link that cannot be guaranteed to be self-controlled will become the weakness of attack, and it is urgent to realize the "domestic substitution" of industrial software.

　　The person in charge of Jialichuang CAM software said frankly: "We decided to open this software to the public for free or at a very low price. First, we hope that China circuit board manufacturing enterprises can have independent and controllable software and have enough confidence to cope with the uncertainty of the external environment; The second is to contribute to the upgrading of industrial chain and the reconstruction of value chain made in China. "

　　It can be predicted that the transformation and upgrading of China’s manufacturing industry and the development of industrial software coexist and are inseparable. On the one hand, the stronger the manufacturing industry is, the more important the industrial software is, which will inevitably lead to more localized and fully functional products to meet the needs of domestic enterprises for low cost, high efficiency and flexibility, and get rid of the "stuck neck" dilemma. On the other hand, mature industrial software will also feed back China’s manufacturing industry, accelerate the process of digital and intelligent transformation of domestic industries, and promote the high-quality development of "China Zhizao".

Yuanxiao is not suitable for breakfast. How to eat delicious Yuanxiao？

　　Every Lantern Festival, that is, on the fifteenth day of the first month, there are all kinds of Yuanxiao, glutinous rice balls and rice cakes. I don’t know what to do. In fact, these Yuanxiao are mainly made of glutinous rice. The common glutinous rice is white and purple, and their nutritional components are basically similar to rice. Every 100 grams of glutinous rice contains about 7 grams of protein, 75 grams of carbohydrates and various vitamins. Yuanxiao and Tangyuan with different flavors are made through processing and ingredients, but their nutritional value is much higher than that of ordinary rice flour.

　　Yuanxiao is not suitable for breakfast.

　　The main component of Yuanxiao or Tangyuan is glutinous rice flour, which contains high carbohydrate, while the stuffing is mainly pure sugar and fruit, plus a large proportion of vegetable oil or animal oil, which has high nutrition and calories.

　　Many people like to eat Yuanxiao as breakfast, which is not desirable. Li Yanling explained that in the morning, people’s gastrointestinal function is the weakest, and the main raw material of Yuanxiao skin is glutinous rice, which is highly viscous and difficult to digest. Once eating too much, it will cause pantothenic acid, heartburn and nausea. In addition, try not to eat Yuanxiao before going to bed, otherwise it will lead to bloating.

　　When is the best time to eat Yuanxiao and Tangyuan except for breakfast and before going to bed?

　　Experts suggest that it is best to eat between meals, 4 to 8 at a time. While eating Yuanxiao and Tangyuan, you can’t eat other foods with high sugar content. It should be noted that when eating Yuanxiao and Tangyuan, you should nibble slowly to avoid being scalded or choking your throat or trachea, causing injury. In addition, don’t eat cold Yuanxiao and fried Yuanxiao.

　　After eating Yuanxiao and Tangyuan, it is best to take a walk, do exercise, facilitate gastrointestinal peristalsis, promote digestion, or eat some food that helps digestion. Chinese medicine believes that hawthorn has the effects of eliminating stagnation, astringing and stopping dysentery, promoting blood circulation and removing stasis. When eating Yuanxiao with hawthorn, it can help digestion and guide stagnation, which is beneficial to digestion. In addition, you can also eat some Jianwei Xiaoshi tablets and yeast tablets to help digestion.

　　What is the best match for Yuanxiao?

　　Yuanxiao is made of sticky glutinous rice, and with compound stuffing, it is not easy to digest, so it’s okay to eat less. It is suggested that Yuanxiao should be accompanied by some digestive foods, such as hawthorn, barley wort, dried tangerine peel, raw radish and so on. Especially, raw radish contains mustard oil and crude fiber, which can promote gastrointestinal peristalsis, eliminate stagnation, relax the stomach, help to discharge waste in the body, and also reduce the absorption of oil.

　　Also remind: although Yuanxiao is delicious, it should be moderate, not for everyone. Patients with diabetes, kidney disease, chronic pancreatitis and cholecystitis should not eat it, especially Yuanxiao, which is processed with sweeteners. Diabetic patients should also consider the total carbohydrate control.

　　Yuanxiao’s "Original Soup into Original Food"

　　After eating dumplings and cooking noodles, people often have a sentence to remind you not to throw away the soup. In fact, from a nutritional point of view, it is more extensive than "original soup to original food". How about eating Yuanxiao?

　　When eating Yuanxiao, don’t forget to "eat the original soup". Glutinous rice flour contains more water-soluble vitamins, such as vitamin B1 and vitamin B2, which are very important to human health. During the cooking process, some of them are dissolved in the soup. According to the determination, 45%-50% of the vitamin B1 is lost, and most of them are dissolved in the soup.

　　Vitamin B1 can promote the synthesis of acetylcholine in human body, thus ensuring normal gastrointestinal peristalsis and digestive gland secretion. If lacking, it will directly affect the normal digestion, absorption and utilization of the human body. In addition, people also consciously use vegetable juice and other methods to add more food to the soup. In order to obtain nutrients more effectively, don’t forget to eat Yuanxiao soup.

　　Who should not eat Yuanxiao?

　　Diabetic patients: The sugar content of Yuanxiao is high. If patients covet the delicious food, their blood sugar will rise sharply, which will not only aggravate their illness, but also induce ketoacidosis.

　　Patients with ulcer disease: Eating Yuanxiao can increase gastric acid secretion, aggravate the stimulation to ulcer surface, and even induce gastric bleeding and gastric perforation in severe cases.

　　Gastrointestinal dysfunction: Yuanxiao is made of glutinous rice flour, which is sticky and difficult to digest. After eating, it can lead to stomach pain, bloating, belching, acid reflux and even diarrhea.

　　Patients with acute gastroenteritis: The patient’s gastrointestinal tract is in a state of congestion and edema. Patients should eat some digestible foods such as rice soup and lotus root starch. Eating Yuanxiao will increase the burden on the gastrointestinal tract.

　　Patients with high fever: The gastrointestinal tract of patients is relatively inhibited when they have fever, so they should eat some easily digestible food such as liquid food, otherwise it will aggravate the condition.

　　Patients with hypertension, hyperlipidemia and gout: These patients are in danger of aggravating their condition by eating Yuanxiao, so it is advisable to eat less.

　　Early recovery from a long illness: At this time, although the patient’s appetite has improved, his digestive function is still weak, and excessive consumption of Yuanxiao is not conducive to recovery.

　　Old and infirm people: these people have decreased digestive function and lost teeth, especially the old people’s swallowing reflex is relatively slow, which may cause the Lantern Festival to get stuck in the throat due to rapid swallowing, leading to breathing difficulties and even suffocation and death.

　　Infants and young children: Children’s digestive function is weak, and their swallowing reflex has not been fully developed. Therefore, when eating Yuanxiao, they should not eat it whole. They should be divided into 1/4, and then eat the second bite after eating one bite. Be sure to chew slowly in case something goes wrong.

　　Four tips for cooking Yuanxiao.

　　Under boiling water: After the water is boiled, put the Yuanxiao into the pot, gently push it away with a spoon, and let it rotate for several weeks without sticking to the pot wall.

　　Slow fire cooking: after the Lantern Festival floats, quickly switch to slow fire. Otherwise, the Lantern Festival keeps rolling, and it is hard to eat when cooked outside.

　　Point cold water: during the cooking process, add a small amount of cold water every time the pot is opened, so as to keep the Yuanxiao in the pot in a rolling state. Boil the water for two or three times, then cook for a while, and you can eat it. The dumplings cooked in this way are soft and hard, sweet and sticky.

　　Cooking in time: the glutinous rice flour with raw Yuanxiao has more water content, which will deteriorate if it is left for a long time, and it is easy to boil when it is frozen. It is best to cook and eat the Lantern Festival now, and don’t leave it for more than 3 days. Once the color of the Lantern Festival is changed, it can’t be eaten. Now buy quick-frozen Yuanxiao should also be eaten in time, it is best not to store it for more than a week.

　　In addition, when tasting Yuanxiao, whether it is boiled or fried, it should be cooked thoroughly. When frying Yuanxiao, it’s best to stick some holes in it to prevent it from bursting and scalding.

Rainy Day in China in the Solar Terms： Spring is ushered in by splashing water in the plum blossom.

　　Xinhua News Agency, Beijing, February 18th 　Title: Rainy Day: Sprinkling water surprises plum blossoms and ushers in spring

　　Xinhua news agency reporter

　　Where does spring come from, and the water will surprise the plum blossoms.

　　"twenty-four solar term" said: "In the first month, water comes from heaven, and it belongs to wood at the beginning of spring. However, those who grow wood must also have water, so beginning of spring has succeeded in rain. And if the east wind thaws, it will disperse into rain. "

　　Rain is the second of the 24 solar terms. Every year around February 18-20 in Gregorian calendar, when the sun reaches 330 degrees, we have a rainy solar term. Since then, the temperature has risen, the rainfall has gradually increased, and everything on the earth has awakened in the rain.

　　If we say that beginning of spring is more of a prelude to spring in meteorology, everything begins to sprout in the rain and solar terms, and spring has quietly arrived.

　　【 Rain, Three Stages 】

　　In ancient times, rainwater was divided into three stages: "One stage was for rex to sacrifice fish; Second, wait for Hongyan to come; Three waiting for the grass to sprout. "

　　It means that when the solar term comes, the ice on the water surface melts and the otters start fishing. Otters like to drag the fish to the shore in turn after they are killed, which is like a sacrifice, so they have the saying of "Rex offering sacrifices to fish".

　　Five days after the rain, the geese began to fly back to the north from the south. In five days, with the rising of the earth’s sun be the spirit, vegetation will begin to sprout.

　　In this way, nature goes to the depths of spring step by step.

　　[Spring breeze wakes up the earth]

　　In Yunnan, Yunnan-Guizhou Plateau, the warm and humid spring breeze has already awakened the earth. Pink peach blossoms and begonia flowers are in full bloom on the streets of Kunming. The willows along the boathouse quietly show their buds, and the tulips open by Dianchi Lake attract many tourists to enjoy flowers and take photos.

　　In the misty spring rain, the white walls and tiles, small bridges and flowing water, bluestone roads and pedestrians in the south of the Yangtze River are all as beautiful as an ink painting.

　　But at this time, the chill of spring can not be ignored. During the rainy season, the direct point of the sun gradually approaches the equator from the southern hemisphere. At this time, in the northern hemisphere, the sunshine hours and intensity are increasing, and the temperature rises rapidly. The warm and humid air from the ocean becomes active and gradually advances northward to meet the cold air, forming rainfall. At this time, the weather is changeable, which is one of the most frequent cold wave processes in the whole year, with cold and hot, warm and cold at first. "Spring covers autumn and freezing" is the wisdom of our ancestors for thousands of years.

　　[Spring ploughing is busy with farming at that time]

　　A year’s plan lies in spring, and busy farming is always the topic of spring. At this time, farmers from all over the country seize the farming season to carry out farming activities such as spring sowing farmland, fertilization in wheat fields, and greenhouse management and protection, and cultivate hope in the fields.

On February 12th, in Chunxiao Seedling Base of Caoba Town, mengzi city, Honghe Hani and Yi Autonomous Prefecture, Yunnan Province, the freshly watered pepper seedlings were full of vitality in the sun. Xinhua News Agency (photo by Zhang Hongke)

　　In Man hong cun, Menghai County, Yunnan Province, villagers are busy transplanting rice seedlings, and the sparkling paddy fields are quickly covered with rows of seedlings. Villager Lao Wu planted more than 10 acres of fields this year. In order not to delay the farming season, he chose mechanical transplanting. "It’s really convenient. It will be inserted in two hours, saving time and effort."

　　Look from south to north. In Yanjin County, Xinxiang City, Henan Province, which is known as "the first wheat in China", the wheat seedlings have not passed their ankles, and millions of acres of wheat in the county are entering the green period. From a distance, full of green. Farmers here have begun to shovel soil and cover ridges in the fields to prepare for watering the green water.

　　During the autumn sowing last year, affected by floods, some areas such as Yanjin County suffered from late sowing of wheat, and the proportion of weak seedlings was high. But Li Yuanzhi, a big grain grower, is still full of confidence. "Near the rain solar terms, the weather forecast says there will be a new round of precipitation in Henan. ‘ Spring rain is as expensive as oil ’ Precipitation is conducive to wheat turning green. " He said that although the current situation of seedlings is not as good as last year, as long as it is done well during the spring tube period, through careful watering and fertilization, it can promote the "weak seedlings to become strong."

　　China, with its vast territory, has great differences between the north and the south. While spring is sprouting in the south, it is still snowing in some areas in the north, but this does not affect people’s expectation of spring.

　　In Heilongjiang, the northernmost province, many vast black lands are covered with snow, and hardworking farmers have begun to prepare for spring ploughing. These days, members of modern agricultural machinery Farmers’ Professional Cooperative in Dongxing, Helen City are overhauling agricultural machinery and replacing worn and damaged parts. "Spring ploughing is about to begin, and we want all agricultural machinery to be ready for ploughing at any time." Liu Chunsheng, chairman of the cooperative, said that more than 7,000 mu of soybeans were planted last year, and more varieties will be prepared this year.

　　[The seeds of dreams sprout in the spring rain]

　　On rainy days, spring is already in people’s hearts. The seeds of dreams are waiting for a timely rain.

　　On February 16th, at the opening ceremony of Coral Experimental Primary School in Nan ‘an District, Chongqing, "Twenty-four solar terms of the lunar calendar" and "Winter Olympics" became high-frequency words. Tan Jin, the headmaster, popularized the symbolic meaning of the ice pier for the children, and also sent a blessing for the new semester — —

　　"In a few days, we will welcome ‘ Rainwater ’ Solar terms This solar term indicates that the geese will return, the plants will sprout and the crops will have a good opportunity to grow. I hope that our coral students will face the spring breeze and spring rain, thrive in the new semester, and constantly surpass themselves like Olympic athletes.
