The supply of HDI PCB in China accounts for 26% of the global total supply. The data surveyed by TPCA shows that HDI PCB market has made a value of 2.66 billion dollars in 2008, with an increase of 15.4% over the same period last year. And it expects to achieve 11.2 billion dollars in global in 2009. Although the global economic downturn has led to the slow pace of the industry, China's market share will remain on the rise.

 

As the expanding of PCB product applications in China, HDI PCB is hopeful to achieve the highest supply growth among all the PCB products. The active handset market will drive the rapid development of this industry, which only accounts for 1 / 4 in China’s PCB industry. About 90% of global handsets use HDI PCB, of which most come from China. Thus, the industry of HDI PCB in China is expected to expand rapidly in the short term.

 

Except for the telecommunication products, HDI PCB can also be widely used in computer, consumer electronics and automotive products. The adoption in medical, industrial and military fields also keeps increasing. China enterprises will pay more attention to the high profit applications when the demand for handset market is declining.

 

In order to meet the trend of miniaturization of electronic products, the research of HDI PCB aims at improving the accuracy, density and reducing the line width / distance of products. Large manufacturers plan to expand the production of multi-layer HDI PCB, with the diameter: Φ0.1mm, line distance: 2mil, layer alignment tolerances: 3mil and impedance control under the range of + / -5%.
