"Focus Interview" 20220901 丨 "Little Giant" in the Invisible Champions Mobile Phone

(Focus interview): Continue to pay attention to the "invisible champion". Smart mobile phones extend information time and space, and also created a new social way, becoming an indispensable part of people's work and life. However, every new and technological change of smartphones will bring changes in the industrial environment and the severe shuffling of head enterprises. And accompanied by it is a single champion in the segmentation of smartphone parts.

MEMS acoustic sensor is a microphone in the application of mobile phones, which is one of the most important components in mobile phones. As the largest acoustic sensor manufacturer in China, Goer has become a supplier of many mobile phone manufacturers at home and abroad. Since 2017, the market share of the MEMS acoustic sensor produced by Goer has ranked first in China and has also maintained its leading worldwide. In 2020, the global market share accounted for 32%, ranking first in the world.

MEMS acoustic sensor was born at the beginning of this century. At that time, due to the rise of smartphones, in addition to clear calls for mobile phones, people's requirements for mobile phones were also capable of being able to camera and synchronized videos. The traditional microphone could no longer meet the needs. In 2003, the US Lou's company took the lead in launching MEMS acoustic sensors.

Due to the high level of technical level, only a few companies in the world were trying to industrialize MEMS acoustic sensors. China's MEMS technology only stays at the stage of scientific research. Goor is keenly aware of its market prospects and decided to develop product development.

Jiang Long, president of Goer Co., Ltd. and Chairman of Goor Micro Electronic Co., Ltd., said: "Foreign competitors have made products one after another, which has strengthened our determination to speed up the speed of Chinese MEMS acoustic sensors. The biggest problem is the talent, because there are already patents that have been deployed by foreign companies at the time, so we can only invite the core talents to cultivate the core talents and overcome the patent barriers to rush out of the siege and get out of our own way. "

Goor was originally a private enterprise with a small number of traditional microphones. It couldn't get a high salary, and the company was in Weifang, Shandong. The conditions are incomparable with the first -line big cities. What are the talents that attract cutting -edge?

Jiang Long said: "It is not easy to persuade an excellent talent to join a newly launched career. You need to communicate, do work multiple times, and exchange the understanding of technology on both sides, and the pursuit of the future."

Song Qinglin is one of the earliest experts in the country to study MEMS technology in China. He has published a number of related papers and applied for a patent. Goer invited Song Qinglin to join with the sincerity of "Three Guci".

Song Qinglin, general manager of Goer Micro Electronics Co., Ltd. said: "Goer dares to propose to make MEMS products. It is the first in China. Dare to try, Goer's entrepreneurial spirit, enthusiasm, ideal, and ambition moved me."

Song Qinglin joined Goel and established the MEMS R & D Center. Because of the basis of scientific research, the team quickly formed a plan for independent research and development, but they found that they encountered a huge challenge: factories that could not find MEMS chips. The manufacturing MEMS chip has a large investment, long cycle, and high technical difficulty, and market prospects are uncertain, so no enterprise is willing to invest in production.

Song Qinglin said: "We have to go abroad to find the MEMS chip manufacturer and make qualified chips through two or three years of hard work outside. After developing mass production overseas, we return to the country. Made in pulling up. "

The situation changed at this point. At that time, the state included new electronic components in high -tech industrial development projects, and provided strong support in policies and funds.

China Resources Shanghua, located in Wuxi, is a manufacturer of integrated circuit products. Due to the support of national special funds, it has invested in the construction of the MEMS chip production line, which has also become the first chip manufacturing company in Goor's cooperation in China. Both companies have formed the most elite team, with difficulties in unwillingness.

Song Qinglin said: "A 4 -hour drive, my team and I have to pass almost every week in the early stage of development. Go to see the results of the test, correct the process and parameters. The time has always been so intimate. "

With the team's efforts, two years later, Goor's first MEMS acoustic sensor using independent development chips to achieve mass production, because the quality was too strong, and quickly occupied a place in the market. Subsequently, Goer developed and produced the smallest chip in the industry, standing at the top of the industry.

However, on the road of development, challenges are always continuous. To maintain vitality, companies must continue to break through themselves and overcome difficulties. The occurrence of noise and distortion is a problem of long -term trouble in mobile phone users. To solve it, it means that there is no dust in the sensor.

There must be no dust in the sensor, which requires all production links to be produced. This is not only a matter of a company, but also related to the entire industrial chain control, especially the requirements for packaging technology and technology are quite harsh, so no companies have dared to try internationally.

What no one dares to do is a valuable opportunity for those who are brave to be challenged and not afraid of failure. Goer decided to seize the opportunity and meet the challenge. Using this opportunity, Goer upgraded his production line to intelligence, and also promoted the upgrading and transformation of the partner production line on the supply chain. The overall industrial level has been greatly improved.

In just 5 months, Goer developed and produced new products required by customers. Many internationally renowned brand phones used this product on their flagship machines. More importantly, through cooperation with Goles, several domestic MEMS chip manufacturing companies have grown up, the entire MEMS industry chain is opened, and the overall manufacturing capacity is close to the international leading level. Jiang Long said: "The mentality and ideas of the industry to report the country are getting more and more rooted with the growth and growth of the enterprise. What we do is not just to solve the employment of a person and a group of people, and the ideals and visions, society, the country, the country, the country, the country, the country The development of the nation is tightly connected together. "

Among the mobile phone component manufacturers, there is another company that has an advantageous position in the market -Sichuan Hongke Technology Co., Ltd.. It also seizes the opportunity of the booming development of smartphones and achieves leapfrog development by relying on a cover glass.

In the mobile phone cover glass industry, Hongke has now been internationally leading, and its market share in domestic and foreign markets is among the top. The high -aluminum ultra -thin touch screen protective glass produced by Sichuan Hongke Innovation Technology Co., Ltd., as of 2021, has the second and first nationwide in the smartphone market.

Today, the production line of Hongke Company is constantly produced every day, and 6 years ago, the production line here was deserted. The company's predecessor Xu Hong Optoelectronics was on the edge of life and death.

Ren Shuming, general manager of Sichuan Xuhong Optoelectronics Technology Co., Ltd. said: "We support Changhong for the machine plate for plasma glass TVs. As Changhong's demand for glass machines has fallen, our warehouse is full of glass. If you don't transform, it will be a dead end. "

At that time, smartphones began to use widely, and the cover glass protected by high -strength screens showed a broad market prospect. Cover glass and plasma TV back panel glass are technically similar, so the company decides to transform the cover glass of smartphones.

At that time, the technology was first developed by the United States, Japan, and Germany. They carried out a patent layout around the world and implemented strict technology blockade. In 2014, there was no domestic company in China that produced cover glass, and the products were imported. In order to express his determination, the person in charge of the enterprise set up a military order at the employee conference.

Ren Shuming said: "We must do it in half a year. If I can't do it. Of course, I will not be a deserter. I will work with everyone as an engineer until this product is successful."

The biggest problem when the team encountered is how to make a large glass as thin as cicada. At that time, the thickness of the cover glass on the market had reached 0.55 mm.

Ren Shuming said: "The thickness of the plates for plasma glass TV for plasma glass TVs were 1.8 mm, from 1.8 mm to 0.55 mm, the challenge was very huge. If it is raised up, it will collapse the entire kiln, which has reached the limit of temperature. "

Wang Zhuoqing, deputy general manager of Sichuan Hongke Innovation Technology Co., Ltd., said: "At that time, experts from Japan invited experts to come over to provide us with technical guidance. In the end, Japanese experts gave up. This piece, including temperature control, cannot achieve this accuracy. The Chinese can not make this glass. When you change the loss of the point early, do the window glass. "

Can the Chinese do not make cover glass? The team members do not believe this evil. In just 40 days, the team innovatively developed key technologies such as dual hotspot melting technology, which enabled the thickness of the cover glass to reach the standard of 0.55 mm or even thinner. After that, the enterprise successfully developed a high -strength screen protection glass formula with completely independent intellectual property rights, and the new product technical indicators released to reach the international advanced level. They named the product: King Panda.

He Huachao, general manager of Sichuan Hongke Innovation Technology Co., Ltd. said: "We represent the breakthrough of the Chinese national industry in this field, so we use the most vivid panda in China, called the brand image of" King Panda ". The Chinese manufacturing team overtakes the wish of developed countries. "

Maintaining crisis and aggressive consciousness at all times, Hongke Company has continuously upgraded iteration in technology. Today, the application scope has also expanded from mobile phones, computer to military, high -speed rail, optical and heat generation and other fields, which has strongly promoted the development of my country's high -end electronic glass industry.

The path of the invisible champion enterprise is the end of the death, and it is a breakout and persistence of a sword for ten years. They believe in "the death of the excellent, the excellence," driven by the awareness of the strong crisis. From them, we can see how Chinese manufacturing can grow healthily until it becomes a world -class. (Source: CCTV)
