Looking at China's silk screen printing ink development from the PCB ink sales war (2)

Third, PCB ink market analysis

1. PCB ink prices continue to decline

With the rise of China’s PCB status in the world, domestic PCB prices have been continuously reduced by 4 to 5 times in recent years, and SMEs have been the most affected. In the context of falling PCB prices, the raw materials and auxiliary materials used for printing were reduced in price, and the price drop was basically the same as that of PCB.

2. Application of light-imaging corrosion resisting plating ink

In view of the fact that the price of photoimaging etching resist plating ink is significantly lower than that of dry film (about 2-3 times), and the utilization rate is as high as 95%, and there is no need to increase investment in any equipment and plant, so in recent years, many manufacturers Rapidly using dry film instead of photoimaging resist plating ink. After a period of time, due to the substantial reduction in costs and the shortened production cycle, many multi-layer mills also used this ink to complete the processing of the inner plates and received satisfactory results. Some large-scale double-faced manufacturing plants also use the automatic line production method of double-sided roll-coating into the drying tunnel to obtain a multiplier effect. So far, the application of this ink has basically spread to SMEs. With the inward migration of printing plates factories in Hong Kong and Taiwan, some advanced coating methods (such as spraying, electrostatic spraying, dip coating, etc.) have also been introduced to mainland China, and the application and promotion of photoimaging resist plating inks A great promotion.

3. Commercialization of screen printing resist ink

Ink printers saw a strong business opportunity in China's PCB ink market. They soon introduced screen printing resist inks of various types and different properties, forming a printing plate ink market. Hong Kong, Japan, and the United States also pushed our company's PCB screen printing resist ink to China as quickly as possible, and established a joint venture company. These brands have stable ink properties and are easy to use. The most prominent feature is the fading ink process. There has been a great improvement - the use of alkaline solution to remove ink, eliminating the need for solvent cleaning and solvent pollution. With the increase in the number of TV boards and recorder boards, UV-cured resist screen printing inks have come out, significantly accelerating the production of PCB plating ink. After a period of time, due to the substantial reduction in costs and the shortened production cycle, many multi-layer mills also used this ink to complete the processing of the inner plates and received satisfactory results. Some large-scale double-faced manufacturing plants also use the automatic line production method of double-sided roll-coating into the drying tunnel to obtain a multiplier effect. So far, the application of this ink has basically spread to SMEs. With the inward migration of printing plates factories in Hong Kong and Taiwan, some advanced coating methods (such as spraying, electrostatic spraying, dip coating, etc.) have also been introduced to mainland China, and the application and promotion of photoimaging resist plating inks A great promotion.

3. Application and popularization of optical imaging solder mask

Although there are applications of thermosetting solder mask inks and UV-curable inks in the category of solder mask inks, these can only be applied to single-sided and low-end electronic product printed boards, and also need to be used in the production of medium and high-grade printed boards. Optical imaging solder mask ink. With the development of curtain coating technology and the general increase in printed circuit board line density, the use of optical imaging solder mask inks has continued to spread to large and small enterprises.

Fourth, the birth of national brands

China's ink manufacturers have been spotted in the development of the printed board industry market. After several trials and trials, they developed their own brand, entered the market with the fastest speed, and began to compete with imported brands.

1. Several forms of national brand birth

1 Spotting the PCB market, investors purchase ink formulations, employ technical personnel, and establish ink manufacturing companies;
2Foreign or Hong Kong or Taiwanese manufacturers set up factories in the mainland and still use the original trademark;
3 Sino-foreign cooperative construction;
4 The former Ministry of Electronics Industry developed the UV solder mask ink (including character inks) and light imaging resists in order to realize the 1985-95 attack plan. The ministries, universities, research institutes, and state-owned giants cooperated. Electroplating ink, optical imaging solder mask ink, and has been put into production.
