As the expanding of PCB product applications in China, HDI PCB ︱High density PCB︱High Density Interconnect 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 ︱High density PCB︱High Density Interconnect 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%.
