Detailed introduction
HDI (High Density Intrerconnection) definition of circuit board refers to the diameter is below 6mil, hole ring ring diameter (Hole Pad) micro vias under 0.25mm (Microvia), the contact density in the above 130 points per square inch, 117 inch above the wiring density per square inch, width / spacing for printed circuit in the following 3mil/3mil. HDI circuit board is mainly used in mobile phones, cameras, video cameras, notebook computers, on the network card, IC board, military, medical and other different areas.
Generally speaking, the HDI circuit board has the following advantages:
1 lower costs
2 increase wiring density
3 is conducive to the use of advanced packaging technology
4 have better electrical performance and signal accuracy
5 reliability is better
6 can improve the thermal properties
7 can improve radio frequency interference, electromagnetic wave interference, electrostatic discharge
8 increase design efficiency
