1. Precision laser cutting in drilling services Application

Because the laser has a high energy, highly focused and other characteristics, laser drilling processing technology is widely used in many industrial process, making hardness, high melting point of the material more easily machined. For example, in the processing of high-melting metal molybdenum plate micrometer pore size; processing tens of microns holes in the cemented tungsten carbide; processing hundreds of microns deep and diamond wire drawing dies, chemical fiber sprayed on red, sapphire silk top. The use of a laser beam in space and time characteristics of highly concentrated, pass through to move the spot diameter can be reduced to the micron level, thereby obtaining 100 ~ 1000W / cm2 laser power densities. Such a high power density laser drilling may be practiced in almost any material. Commonly used HDI PCB drilling has micropores reversal of high power density, high temperature ceramics and other non-metallic materials for high precision drilling.

HDI (High Density Interconnection Technology) as a new PCB design and production techniques, step by step manner and use it instead of blind or buried vias (usually by laser into the hole) are electrically connected, also known as laminated (Build- Up) technology. Using HDI technology products aperture disc diameter and lines are greatly reduced, but also has better thermal performance, implement and conform to the size and weight of consumer electronics demand. With a wide range of electronic products toward the short, small, light, thin trend, adapt the scope of application of this trend HDI board more widely, its share in GDP is also growing PCB.

HDI board PCB industry usually defined as a conductive layer thickness of less than 0.025mm, the insulating layer thickness of less than 0.075mm, line width / line pitch is not more than 0.1mm / 0.1mm, the diameter of the through hole is not greater than 0.15mm, and the I / O number greater than 300 A circuit board, which is a high-end PCB type.

HDI trends from the industry perspective, the increasing application of high-performance materials, increased fine line (line width / spacing of 3mil / 3mil), the increase in micropores (5mil and below) and embedded passive circuit, lead-free HAL peaceful immersion silver increases, increase 01005 assembly components, which are reflected in the future HDI line getting smaller, more dense, pore smaller, more dense, increasing environmental requirements. HDI is expected to develop technology and will focus on high density of green (lead-free and halogen-free), with increasing levels of HDI technology, the traditional mechanical drilling and plating methods have become more difficult to meet the HDI Processing Technology requirements, as the more advanced laser technology HDI manufacturing services assistive technology will gradually replace the mechanical drilling and electroplating process in HDI will become a mainstream technology.

2. Drilling Market Analysis 

HDI biggest feature is the replacement effect is strong, cyclical weak, is currently the fastest growing PCB industry sub-sectors. Taiwan ITRI IEK HDI board market is expected to develop rapidly, mainly from mobile phones and IC packaging applications, the next wave is from the application of the notebook. HDI global application market 55% concentrated in the mobile phone market, about 28 percent applied to the carrier board. PCs account for about 11%, mainly in notebook computers. Others include automotive, medical equipment and other products DVC, about 6%.

CPCA (China Printed Circuit Industry Association) statistics, from 2006 to 2008 HDI domestic market growth rate of more than 30%, China HDI use an area of ​​2.85 million square meters in 2006. According to HDI average 232,500 holes per square meter, the price per thousand Hole 0.80 yuan, the proportion of 55% of outsourcing is estimated that in 2006 HDI drilling outsourcing market reached 292 million yuan, an increase of 40% in 2007, reaching 409 million yuan, in 2008 growth 30%, the market size of 531 million yuan. 2009 market size of 652 million yuan, is expected to market size in 2012 was 1.249 billion yuan.

Key enterprises in this field are: Multiple Technology (Singapore listed company) accounted for about 6% of the market share, excellent health holding about 6% market share.

Industry trends and the reasons for the profit level 

Currently precision manufacturing and service sectors gross margin declined slightly. The main reason is increased competition, new entrants increase competition manufacturers, resulting in lower prices, but due to the increase of steel, labor and other costs, making the gross margin decline.

The next few years, with the implementation of the technological level and improve the industry's national favorable policies, China laser industry are bound to be greater development. Laser technology combined with many emerging disciplines, will be closer to people's daily lives, and the solid-state laser research direction, semiconductor lasers and diode-pumped solid-state lasers become the dominant direction of the laser processing equipment, the entire laser industry mergers and acquisitions will be popular, Companies strive to become the industry giant, laser products will also be further used in industrial production, transportation, communications, information processing, health care, military, and cultural and educational fields, and thus enhance the independent innovation ability of these industries to adapt to globalization The development trend, the formation of new economic growth point.

The national macro-control policy of fixed asset investment, the demand for industry products, may also have a direct impact. With the development of the industry, technology maturity increases, it is difficult to exclude competitors due to the increase in competitor's strength and other factors, led to the company's market share to reduce the possibility of falling prices. Thus, industry sales and profits as the factors discussed above, a certain degree of fluctuation may occur. But overall, China's laser industry is an emerging sunrise industry, the market demand is huge, lucrative.
