High-density HDI circuit boards are mainly concentrated in 4-layer or 6-layer boards, which are interconnected 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 soon 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 boards with a 2+2 structure require this technique.
High-rise HDI circuit boards are usually traditional multi-layer boards with laser drilling from 1 to 2 layers or 1 to 3 layers. Another feature of it is the processing of micropores in the glass fiber reinforcement through the necessary continuous lamination process. The effect of this technique is to reserve sufficient component space 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 buried via process. The microvia process is aimed at spacing between high-density devices such as high-I/O devices and UBGAs. The dielectric raw material of HDI circuit board products can be copper clad laminate (RCF) or prepreg.
