High-density HDI board and high-level HDI circuit board

Today, the editor of Shenzhen Zhongke circuit board manufacturer tells you about the high-density HDI board and high-level HDI circuit board:
High-density HDI circuit boards are concentrated in 4-layer or 6-layer boards, which are connected to each other according to buried holes, and at least two layers have micro-holes. The main purpose is to better meet the demand for increased I/O with high flip chip density. This technology will quickly be integrated with HDI to complete product miniaturization. High-density substrate HDI boards are suitable for flip-chip or bonded substrates. The microvia process provides enough space for high-density flip chips. Even HDI circuit boards with a 2+2 structure require this technology.
The high-level HDI circuit board is usually a traditional multi-layer board, and the laser perforation is from 1 to 2 layers or 1 to 3 layers. Another feature of it is that micro-holes are processed in the glass fiber reinforced material through the necessary continuous lamination process. The function of this technology is to reserve enough space for components to ensure the required impedance level.

High-level HDI boards are suitable for high-level HDI boards with high I/O counts or fine-pitch components. This hdi board does not require a buried hole process. The purpose of the microvia process is the spacing between high-density devices (such as high I/O devices and ubga). The dielectric material of HDI circuit board products can be copper clad laminate (RCF) or prepreg.
