Thirty-one Song Jinquan: welding from the workers became the first trainer

 August 29, 2006, Song Jinquan away from state-owned enterprises, private enterprises to join the Sany Heavy Industry. In the moment of entering the thirty-one as welding technology workers, he quietly set a goal in mind - "in the Trinity this platform to make a difference, to reach the highest skill."

From the power of faith, Song Jinquan day and night fighting in the welding line, he's hard at the shop is out of the name. His near-stringent demands on themselves, to each site welding jobs are valued as a rare opportunity to exercise. From the simple to the difficult operating analysis, he figured, trial and error, with the perseverance of the spirit and idea came to study the perception of his increasingly sophisticated welding techniques.

Hard work pays off. In 2008, Trinity Group Phase I training technicians and senior technicians, and Song Jinquan with perfect welding conquer the presence of all the judges, as this training course successfully pass the examination of the only high-level technicians; 2009, he was doing my part won the "Crane Division mechanic welding skills Star Contest" winner; 2010, Japan Welding Technology courses, he won the "outstanding student" title ... ...

One in three years, Song Jinquan with practical work hard to obtain recognition of the leadership and colleagues, from the group leaders, small pieces of the frame to the squad leader is responsible for the Crane Division, welder training, he gains a career breakthrough.

"As long as people have goals, dreams, and go step by step firmly, they will achieve." Trinity the past five years about life, Song Jinquan passion, emotion.

Welding process has been an important constraining factor in the quality crane products. Qi Jian, general manager of business has on many occasions, the improvement of the welding process the request. In order to fundamentally improve the standard of welding technology, welding technology skills training for staff was promoted to the strategic level. Crane Division, welding technology as the highest level of senior personnel, Song Jinquan stepped in, becoming the first Division welding teacher training, training in the manufacture of a busy day, hard line.

Welding process is repeated to strengthen the operation of technology, the upgrading of skills is not achieved overnight, combined with new multi-skilled workers into the Division of 80, 90 young people, the lack of practical experience, Song Jinquan to communicate with them over and over again at pains to talk. At first these young people will feel tired, very strong resistance. However, the sincere and exquisite eventually conquered the group of young people who became good friends, the workshop has become common practice in the skills competition, crane manufacturing process improvements to a new level.

"Three in a career with our dreams, I am willing to work hard here and these young people belong to our world together." About the future, Song Jinquan face happiness and satisfaction.

How to improve the quality of the appearance of solder resist

An Introduction

People talk about the development trend of PCB, the PCB is often thought of moving high-precision, high density and reliability direction, which is the development trend. On the other hand, the appearance of the user requirements of the PCB more strict. PCB solder mask is like a "coat", in addition to requiring a certain degree of thickness and hardness, solvent resistance test and adhesion test standard, but also requires the surface color of uniform, shiny (general requirements for domestic rooms the brighter the better), the surface no garbage, no extra marks. We can say that the appearance of solder resist is not only a good or bad quality of enterprise technology and management level of expression, but also directly affect the "order." Therefore, how to improve the appearance of printed circuit board solder quality has become the PCB plant need to be addressed for each subject. According to my practical experience following from the solder resist printing, exposure, developing and post-cured in four areas to talk about how to improve their appearance.

Affect the quality of the appearance of two factors solder resist

1, screen:

Photosensitive solder mask of the screen printing process, the flatness of the blade, clean the environment between the degree of screen printing, screen printing, when used close up tape and ink formulation, printing pressure, pre-screen appearance of the brush plate and so will the quality of impact. According to the actual situation of production, the most influential factor is the first three. Scraper is not easy to solder flat surface scraper marks; screen cleaning is not enough room in the solder surface is easy to waste; close up tape improper use, easy to make plastic dissolved in solvent ink resulting surface compounds.

2 Exposure:

Solder mask exposure process, because solder has not completely cured, solder and solder resist film prone to stick together when the imprint, which is affecting the quality of the main reasons for the appearance of solder resist.

3, developing:

The current level of solder mask imaging commonly used transmission-type imaging, the solder has not completely cured, imaging machine drive wheel, roller and so easy to damage its surface, resulting in roll mark, thus affecting the appearance quality of solder resist. In addition, incorrect exposure will also affect the energy of the solder resist gloss, but this can be controlled through the wedge table.

4, after the curing
basket cable trays, flexible cable tray, electrical cable tray
After the curing temperature of the solder resist non-uniform color likely to cause uneven solder resist, even when the temperature is too high, resulting in local yellow, black, affecting the appearance of solder resist.

Conclusion

To improve the appearance of printed circuit board solder quality is required from the process methods, materials, equipment, operator of integrated process control and other aspects of discipline, in particular, be on the screen, exposure, developing, after the curing process of the parameters strict monitoring.

Space 7103 factory workshop to improve welding

"When carrying the product shape by hand soldering process dominated for decades we have been playing a card hand-welding, advanced welding equipment utilization is not high." "Because of the lack of innovation, new models of development, when the sign design had to accommodate the backward process, which restricted the development of scientific research and production factory. "" Whether it is young technicians, or skilled personnel, to teach him techniques, but also to teach him a man. "This is the China Aerospace Science and Technology Corporation six homes 7103 plant recently held a symposium on-site welding skilled lively discussion of the scene.
Welding technology in the plant space rocket engine development and application of industrial business development, has a very important role in the plant belongs to the core expertise and strength. In order to further find out the status of factory welding techniques, welding technology and products to improve the quality of the plant called from the front line leadership of senior engineers, senior technicians, on the "innovation and development of welding technology, welding technology and skilled personnel training, quality of welding increase, the current welding technology and welding technology exchange ", etc. offer advice and suggestions.
Combination of rocket engine development and the development of space applications, industrial management, more than 20 elite targeted welding skills, talking about, for their valuable comments and suggestions: put some welding to reduce individual differences, to strengthen the development of welding tooling; some Abstract from the subtle use their brains to enhance the welding process control; some mention of automatic welding equipment to strengthen the research and application, to avoid new products to the craft behind the stereotypes; some mention play all plant equipment and technology, solutions and new models developed new product development process of technical problems; to mention research and production projects, some welding technology driven innovation; some mention to strengthen the welding technology, skills, personnel training and technical exchanges, and so on.

In 2009 the trend of demand of welding equipment

According to the general trend of China's economic development, within the next few years, China's annual steel production and steel imports remained stable, and thus accounting for the domestic steel production to market demand for welding products, there will be no major discrepancies. Single market for products will be as welding technology, process development and production mechanization and automation level, and changes in the composition of various products in particular, than, as the proportion of AC arc welder decreased, automatic, semi-automatic welding machine, in particular, CO2 welding machine, welding sets dedicated a significant increase in demand.

Welding products, imports will continue to increase, the total value of imports of the domestic market still accounts for about 50% of the total; domestic exports of welding over the years, no more than 6% of GDP. With the new product development ability and production level, the introduction of product localization and large-scale implementation, particularly foreign investment, joint venture development and the rapid rise of private enterprise, not only have a greater volume of its export growth, and exports The area also from the current Middle East, South Asia and Africa and other developing countries, expanding to the United States, Europe and other industrialized countries.

At present, the total market in the form of welding is: product output oversupply, competition, the majority of the production, management difficult. In product composition, the general oversupply of general-purpose welding machine: high reliability, multi-functional automatic, semi-automatic welding machines and special sets of welding, special welding market demand fast, still has to import some welding; in the domestic market structure on and imported welding is basically evenly divided, although the total number of Taiwan-made welding dominant, and in the sales of the imported products were accounted for about half. Although the situation is a result of domestic exports of welding products and the introduction of products to improve the performance of domestic implementation, and joint ventures, foreign expansion of production scale, export growth, exports and gradually by the AC arc welding machine, welding machine DC-based rotation turned to automatic, semi-automatic welding machines and welding sets, but imports of the same type of product, the gap is still significant.
